Fully configurable CPU to emulate with a single .bochsrc option ! 775- 10% (ST) to 50% (SMP) CPU emulation speedup ! 776- Implemented support for new x86 ISA extensions, Bochs is aligned with 777 latest published Intel Architecture Manual (rev 040, AVX rev 011): 778 - XSAVEOPT, AVX/AVX2/FMA/F16C, BMI1/BMI2, SMEP, INVPCID, TSC-Deadline 779 - VMX: VMX Preemption Timer, Pause Loop Exiting and VM Functions 780- Implemented support for AMD SSE4A/XOP/FMA4/TBM instruction sets 781- Networking: introduced new networking module 'slirp' 782- Harddrive: fixed buffer overflow causing Bochs crash in LBA48 mode 783- VGA: Added PCI ROM support to cirrus and pcivga and moved ROM loading 784 for the ISA case to the vga code (SeaBIOS now usable by Bochs) 785- Sound: ported ES1370 soundcard emulation from Qemu 786- Continuing configure rework, check for more removed configure and .bochsrc 787 options and their replacements ! 788- LGPL'd VGABIOS updated to version 0.7a 789 790Detailed change log : 791 792- CPU 793 - Now you can configure CPU to emulate using a single .bochsrc option ! 794 The option selects CPU configuration to emulate from pre-defined list 795 of supported configurations. When this option is used, Bochs CPU emulation 796 engine is automatically configured to emulate a specific real hardware CPU, 797 including exact CPUID matching reference hardware. Check .bochsrc example 798 or check user manual for list of supported configurations and more details. 799 * It is also possible to choose the CPU to emulate from Bochs command line 800 using command line interface to .bochsrc: "cpu::model <cpu_name>" 801 * Query for supported CPU models using command line option: -help cpu. 802 803 - 10% emulation speedup with handlers chaining optimization implemented. The 804 feature is enabled by default when configure with --enable-all-optimizations 805 option, to disable handlers chaining speedups configure with 806 --disable-handlers-chaining 807 - New way of CPUs scheduling in SMP mode brings up to 50% speedup to the 808 SMP emulation. New implementation uses dynamic CPU quantum value and takes 809 full advantage of the trace cache. Each emulated processor will execute 810 the whole trace before switching to the next processor. 811 * It is also safe to use large (up to 16 instructions) quantum values for 812 the SMP emulation now and improve performance even further. 813 814 - Implemented Supervisor Mode Execution Protection (SMEP), the feature can 815 be enabled using .bochsrc CPUID option. 816 - Added support for XSAVEOPT instruction, the instruction can be enabled 817 using .bochsrc CPUID option. 818 - Added support for AVX and AVX2 instructions emulation, to enable configure 819 with --enable-avx option.

MTRRs is enabled by default when cpu-level >= 6. 1684 - Implemented experimental MONITOR/MWAIT support including optimized 1685 MWAIT CPU state and hardware monitoring of physical address range, 1686 to enable use --enable-monitor-mwait configure option. 1687 - Removed hostasm optimizations, after Bochs rebenchmarking it was found 1688 that the feature bringing no speedup or even sometimes slows down 1689 emulation! 1690 - Merged trace cache optimization patch, the trace cache optimization 1691 is enabled by default when configure with --enable-all-optimizations 1692 option, to disable trace cache optimization configure with 1693 --disable-trace-cache 1694 - Many minor bugfixes in CPU emulation (both ia32 and x86-64) 1695 - Updated CPU instrumentation callbacks 1696 1697- Bochs Internal Debugger and Disassembler 1698 - Many fixes in Bochs internal debugger and disassembler, some debugger 1699 interfaces significantly changed due transition to the param tree 1700 architecture 1701 - Added support for restoring of the CPU state from external file 1702 directly from Bochs debugger 1703 1704- Configure and compile 1705 - Renamed configure option --enable-4meg-pages to --enable-large-pages. 1706 The option enables page size extensions (PSE) which refers to 2M pages 1707 as well. 1708 - Removed --enable-save-restore configure option, save/restore feature 1709 changed to be one of the basic Bochs features and compiled by default 1710 for all configurations. 1711 - Added new Bochs benchmark mode. To run Bochs in benchmark mode execute 1712 it with new command line option 'bochs -benchmark time'. The emulation 1713 will be automatically stopped after 'time' millions of emulation 1714 cycles executed. 1715 - Another very useful option for benchmarking of Bochs could be enabled 1716 using new 'print_timestamps' directive from .bochsrc: 1717 print_timestamps: enable=1 1718 - Added --enable-show-ips option to all configuration scripts used to 1719 build release binaries, so all future releases will enjoy IPS display. 1720 - Enable alignment check in the CPU and #AC exception by default for 1721 --cpu-level >= 4 (like in real hardware) 1722 1723- SF patches applied 1724 [1491207] Trace Cache Speedup patch by Stanislav 1725 [1857149] Define some IPL values by Sebastian 1726 [1850183] Get memory access mode in BX_INSTR_LIN_READ by Lluis Vilanova 1727 [1841421] pic: keep slave_pic.INT and master_pic.IRQ_in bit 2 in sync by Russ Cox 1728 [1841420] give segment numbers in exception logs by Russ Cox 1729 [1801696] Allow Intel builds on Mac OS X 1730 [1830658] Fix >32GB disk banner by Samuel Thibault 1731 [1813314] Move #define IPL_* and typedef ipl_entry by Sebastian 1732 [1809001] Save PnP Option ROM Product Name string in IPL Boot Table by Sebastian 1733 [1821242] Fix for #1801285, Niclist.exe broken by Sebastian 1734 [1819567] Code warning cleanup 1735 [1816162] Update comment on bios_printf() by Sebastian 1736 [1811139] Trivial Fix when BX_PCIBIOS and BX_ROMBIOS32 not defined by Myles Watson 1737 [1811190] Improve HD recognition and CD boot by Myles Watson 1738 [1811860] Implement %X in bios_printf by Sebastian 1739 [1809649] printf %lx %ld %lu by Myles Watson 1740 [1809651] move BX_SUPPORT_FLOPPY by Myles Watson 1741 [1809652] dpte and Int13DPT fixes by Myles Watson 1742 [1809669] clip cylinders to 16383 in hard drive by Myles Watson 1743 [1799903] Build BIOS on amd64 by Robert Millan 1744 [1799877] Fix for parallel build (make -j2) by Robert Millan 1745 1746- these S.F. bugs were closed 1747 [1837354] website bug: View the Source link broken 1748 [1801268] Reset from real mode no longer working 1749 [1843250] Using forward slashes gives invalid filename 1750 [1823446] BIOS bug, local APIC #0 not detected 1751 [1801285] Niclist.exe broken 1752 [1364472] breakpoints sometimes don't work 1753 [994451] breakpoint bug 1754 [1801295] NSIS installer vs Windows Notepad 1755 [1715328] Unreal mode quirk 1756 [1503972] debugger doesn't debug first instruction on exception 1757 [1069071] div al, byte ptr [ds:0x7c18] fails to execute 1758 [1800080] Wrong "BX_MAX_SMP_THREADS_SUPPORTED" assertion 1759 1760- these S.F. feature requests were implemented 1761 [1662687] Download for Win32-exe with x64 Mode and debugging 1762 [604221] Debugger command: query lin->phys mapping 1763 1764------------------------------------------------------------------------- 1765Changes in 2.3.5 (September 16, 2007): 1766 1767Brief summary : 1768- Critical problems fixed for x86-64 support in CPU and Bochs internal debugger 1769- ACPI support 1770- The release compiled with x86-64 and ACPI 1771- Hard disk emulation supports ATA-6 (LBA48 addressing, UDMA modes) 1772- Added emulation of Intel SSE4.1 instruction set 1773 1774Detailed change log : 1775 1776- CPU 1777 -

Now you can compile with many more 3193 options, and choose between them at runtime. 3194- added emulation of AMD x86-64, MMX, SSE, SSE2 instructions 3195- add wxWindows port (a graphical configuration interface and display lib) 3196 and SVGAlib port (full screen display for Linux without X11) 3197- improvements in many I/O devices: for example up to 8 hard disks/cdroms, 3198 TUN/TAP network interface, 360k floppies, 3199- improved MacOSX/Carbon interface and updated MacOS9 port 3200- GDB remote stub, allows symbolic debugging with Bochs simulation. 3201- support for up to 32gig hard disk images 3202 3203Detailed change log follows. 3204 3205- documentation 3206 - manpages updated (Volker, Christophe) 3207 - install HTML rendering of docbook documentation instead of 3208 docs-html (Bryce) 3209 - doc/docbook/Makefile is now generated by configure script. 3210 if configure detects docbook2html on your system, it will turn on 3211 --enable-docbook and run make in the doc/docbook directory. Also 3212 make install will install documentation into $(docdir). You can use 3213 --disable-docbook to turn this off, if necessary. (Bryce) 3214 - add "make bochsdoc.tar.gz" target to create a documentation tarball. 3215 If you do "make webinst" and you have write access on SF shell server, 3216 it updates doc/docbook/* on the website (Bryce) 3217 - user documentation additions: 3218 - new options (Bryce, Volker, Christophe) 3219 - Bios tips section (Christophe) 3220 - Tuntap section (Christophe) 3221 - Serial Port section (Christophe) 3222 - "Will it Work for Me" / "Is Bochs Right for Me" sections 3223 (N. David Guarneri) 3224 - VESA section (Jeroen Janssen) 3225 - several documents, previously existing as separate html files, have 3226 been included : 3227 - internal debugger section (Christophe) 3228 - gdb stub debugger section (Christophe) 3229 - WinME, WinNT, WinXP, The Hurd, Japanese Win95 install tips (Christophe) 3230 - Win95, Win98 install tips (N. David) 3231 - SB16 section (N. David) 3232 3233- configure script/compile/porting to other OSes/installation 3234 - added plugin architecture 3235 - plugin code written by Bryce, Christophe, Volker based on 3236 plex86's plugin code by Kevin. Testing help from Psyon and Br'fin. 3237 - Plugins are shared libraries that can be loaded on demand. Example: 3238 the serial device is implemented as a plugin. In UNIX, the 3239 serial plugin is called libbx_serial.so. When Bochs reads its 3240 configuration file, if the serial device is enabled it loads 3241 libbx_serial.so. 3242 - all display libraries, most I/O devices are converted to plugins now 3243 - plugins supported on Linux, Solaris, and MacOS X using libtool, 3244 Cygwin using dlltool. On MacOSX, you must have dlcompat installed 3245 and in your include/library paths at configure time. (See .conf.macosx 3246 for an example.) 3247 - we use libtool's LTDL library from libtool 1.4.2, with a number of 3248 critical bug fixes (Bryce Denney) 3249 - the Linux binary RPMs are built with plugin support 3250 - to compile with plugins, configure with --enable-plugins 3251 - the LTDL_LIBRARY_PATH variable tells Bochs where its plugins can be 3252 found. Bochs has a compile-time default for this variable which is 3253 correct if you do a make install. You would only need to set the 3254 variable if the default is wrong. 3255 - for win32 plugins we added "BOCHSAPI" in front of many classes 3256 and methods, to aid in building DLLs. This turns into __declspecs 3257 which are used when making an export library for Bochs. 3258 - allow many display libraries to be configured and compiled at 3259 a time. For example --with-win32 --with-sdl --with-rfb. 3260 Also, we added an experimental option --with-all-libs which 3261 tries to detect which --with-* options will work. If the 3262 autodetection fails, just type the --with-* options explicitly. (Bryce) 3263 - add #if's around all files which are conditionally compiled such 3264 as cdrom.cc and sb16.cc. This makes it possible to compile every 3265 source file all the time, which has the potential to simplify the 3266 configure script and makefiles. At present we only take advantage 3267 of this capability in the win32 VC++ workspace. (Bryce) 3268 - the MacOS9 port has been updated so that it works again. It had 3269 not been updated in at least 2 years, maybe more. (Christophe Bothamy) 3270 - improve support for FHS standard (Robert Millan, Volker Ruppert) 3271 See patches 551811 and 650066. 3272 - keep separate CFLAGS and CXXFLAGS for Bochs (usually a graphical 3273 program) and console programs such as bximage and niclist. Some 3274 sdl and wx compile flags were making bximage and niclist unusable.(Bryce) 3275 - add concept of cross-configuring in the configure script. If you 3276 use the --target option to generate makefiles to be used on another 3277 machine, some detection of compilers and libraries is disabled. (Bryce) 3278 - fix term compile on Cygwin, but it has to be done without -mno-cygwin, 3279 which means that several win32 features such as networking do not work. 3280 - add "-Wno-multichar" on beos 3281 - test for largefile support, and add required CFLAGS (Bryce) 3282 - add -lm when it's needed, and not when it's not (Bryce) 3283 - add configure support for 8 processors. Bochs can support up to 15 3284 with some work on the BIOS. 3285 - fix nmake makefile generation (Psyon) 3286 - improved pthread detection function from ac-archive project on SF 3287 - add installer package for Windows, using Nullsoft (Michael Rich, Bryce) 3288 - on MacOSX, add startup script that creates a text console and then 3289 runs Bochs. Also add make target to create a DMG disk image (Br'fin) 3290 - do not restart the font server on Unix/X11, if vga.pcf was already 3291 installed. On several modern machines, if you restart the font 3292 server the user has to restart X windows. (Bryce) 3293 - update most .conf.* files with modern options such as 3294 --enable-all-optimizations. (Bryce) 3295 - The MacosX .conf script adds /sw/include and /sw/lib to the compile/link 3296 path list because it is a common place to put dlcompat. Dlcompat is 3297 required when building with plugins. (Bryce) 3298 - rpms can now be built without root privileges (Bryce) 3299 3300- command line 3301 - fixed up our command line options (Volker, Bryce, Christophe) 3302 Usage: bochs [flags] [bochsrc options] 3303 -n no configuration file 3304 -f configfile specify configuration file 3305 -q quick start (skip configuration interface) 3306 --help display this help and exit 3307 3308- configuration file (bochsrc) 3309 - There are several new options. See the documentation for more details. 3310 - config_interface: select text mode menus or wxWindows for configuration 3311 - display_library: select which display lib to use 3312 - optromimage: load optional rom images 3313 - ataN (N=0,1,2,3): up to 4 ATA controllers for hard disks, cdroms 3314 - ataN-master, ataN-slave, N=0,1,2,3: defines a hard disk or cdrom. 3315 The "ata*" options replace diskc, diskd, and cdromd, which are 3316 now deprecated. 3317 - floppy_bootsig_check: control the 0xaa55 signature check on boot floppies 3318 - logprefix: lets you change the format of log messages 3319 (patch by Carl Sopchak, help from Christophe) 3320 - debugger_log: log all output from bochs debugger 3321 - user_shortcut: allow you to type key combinations like Ctrl-Alt-Del 3322 - pit: control the PIT model, including realtime option to try to 3323 keep in sync with real time. 3324 - Credits: Christophe added optromimage, everything about ATA, 3325 floppy_bootsig_check, debugger_log. Bryce added config_interface 3326 and display_library. Volker did the user_shortcut button. 3327 Greg Alexander wrote the PIT model and added the realtime option. 3328 - since v1.3 we've been able to use environment variables in pathnames 3329 in the bochsrc file. Now, a few variables have default values, set at 3330 compile time, that are used if the user does not set a value. If Bochs 3331 is installed correctly, the defaults will be correct and the user will 3332 not need to override them. 3333 - $LTDL_LIBRARY_PATH is the path name where the plugins can be found. 3334 The default value comes from $(plugdir) in the makefile. This is only 3335 important if plugins are enabled. (Bryce) 3336 - $BXSHARE is the path where the BIOSes and keymaps are installed. 3337 The default value comes from $(sharedir) in the makefile. Disk 3338 images on the Bochs website will begin to use BIOS pathnames like 3339 $BXSHARE/BIOS-bios-latest. On win32, the $BXSHARE default is 3340 set by the NSIS installer and read from the registry. On MacoSX, 3341 the $BXSHARE default is set to the path containing bochs.app. 3342 (Bryce, Volker, Br'fin) 3343 - new option in the configuration interface to reset all bochsrc 3344 settings to initial defaults. A reset occurs just before reading 3345 a new configuration file, so that leftover parameters from a 3346 previous configuration do not affect the new configuration. Also, 3347 you can request a reset using the configuration interface. (Volker, Bryce) 3348 - ne2k line can now specify a script to set up the interface (Christophe) 3349 - on Unix, also search /etc/bochsrc (Bernhard Bablok) 3350 - you can use #include in the bochsrc to read configuration from other 3351 files (Volker) 3352 3353- CPU 3354 - speed optimizations from Kevin Lawton, yielding around 2x speedup 3355 - guest2host_tlb : for entries in the paging TLB which point to normal 3356 physical memory pages, a pointer to the host address of the emulated 3357 physical memory (from malloc()) page is stored in the TLB entry. In 3358 many cases, this pointer can be used in memory accesses to directly 3359 read/write the guest memory address. In exceptional cases, the physical 3360 memory access routines are used. Turn on with --enable-guest2host-tlb. 3361 - repeat IO/string : for some variants of repeatable IO and string 3362 instructions, the segmentation and paging checks are done in batch along 3363 with the data transfers, constrained within page boundaries and the 3364 segment limits. Turn on with --enable-repeat-speedups. 3365 - icache : The structure holding instruction decode information was 3366 reduced to 32 bytes. 24 bytes for the actual decode data, and 4 each 3367 for pointers to the address resolution routine (not always needed) and 3368 the instruction emulation routine. With a reasonably small 3369 per-instruction decode size, an instruction cache (iCache) was created, 3370 which is simply a hash table. The main cpu loop looks in the table 3371 first; if the instruction has already been decoded, execution can begin 3372 immediately without decoding. Turn on with --enable-icache. 3373 - host specific asm : when compiling on an x86 platform, use of 3374 x86-specific asms can be enabled to accelerate several facets of 3375 emulating instructions. For example, the EFLAGS values are much more 3376 efficient to calculate when the actual x86 instructions are used to 3377 generate the EFLAGS values. Turn on with --enable-host-specific-asms. 3378 (Kevin, with help from Jas Sandys-Lumsdaine) 3379 - if you want to enable all the speed optimizations that we believe 3380 to be stable, use --enable-all-optimizations. The release binaries 3381 are built with this option. 3382 - add support for AMD's x86-64 instruction set. To enable, configure with 3383 --enable-x86-64. The AMD x86-64 support is about 90% complete and is 3384 still experimental. We've implemented the core x86-64 instruction set and 3385 the changes to the rest of Bochs necessary to operate in long mode, but 3386 we've still to implement checking for canonical 64 bit addresses. The code 3387 has been tested on a limited number of test programs. It has been able to 3388 successfully boot a x86-64 Linux kernel and run a 64 bit userland 3389 application. It has also successfully run a DOS based 64 bit protected 3390 mode test application. (Peter Tattam, with merge/bugfix help from Kevin 3391 Lawton and Bryce Denney) 3392 - add MMX support. To enable, configure with --enable-mmx. 3393 (Stanislav Shwartsman) 3394 - add SSE and SSE2 support. To enable, configure with --enable-sse=1 3395 or --enable-sse=2. (Stanislav) 3396 - fixed the behaviour of the bcd instructions AAM, AAD and DAA based on 3397 SF patch #537146 (Volker) 3398 - stop printing an error for VERR/VERW. According to the i386 opcode 3399 description there is no error present. (Volker) 3400 - fix bug [ 625878 ] reset doesn't reset something(?). Fix cpu reset 3401 when executing a rep instruction (Christophe) 3402 - use accessors methods for CFLAGS and several other registers, so that 3403 the implementation can be changed transparently later (Bryce, Stanislav) 3404 - add support for page size extensions, also known as 4meg pages. 3405 Turn on with --enable-4meg-pages. (Kevin Lawton) 3406 - add support for page global extensions. Turn on with 3407 --enable-global-pages. (Kevin) 3408 - add support for physical address extensions. Turn on with --enable-pae. 3409 (Peter Tattam) 3410 - implement RDMSR and WRMSR. not all MSRs are supported (Zwane Mwaikambo) 3411 - new configure option --enable-ignore-bad-msr, which makes unrecognized 3412 MSR reads and writes into just a warning 3413 - fix PIC/APIC interrupt problem that caused Linux 2.4.19 to hang 3414 during boot (Peter) 3415 - CMPXCHG8B patch (Michael Hohmuth) 3416 - EFLAGS are now stored in the same form as the native EFLAGS on an x86, 3417 so that we can use native machine instructions in some cases (Kevin) 3418 - instrumentation code updated (Stanislav) 3419 3420- FPU 3421 - fixed bug [ 452275 ] fprem emulation bug (Volker) 3422 - fixed bug [ 648579 ] Mac OSX >>PANIC<< FPU_printall. There was an 3423 endianness issue with the fpu (Christophe) 3424 3425- I/O devices 3426 - rewrote pc_system timers (Kevin) 3427 - biosdev 3428 - this new device handles the panic/error/info/debug messages sent 3429 by the Bios and VGABios. It was previously done in the unmapped device. 3430 - cdrom 3431 - implementation of the function READ TOC for cdrom image files. (Volker) 3432 - function capacity() for win32 fixed. Now it returns the number of blocks 3433 instead of bytes. (Volker) 3434 - added multiple cdrom support for win32 (NT/2000 version untested). The 3435 ASPI version uses the cdrom drives in the system's order. Drive letters 3436 are not used by ASPI. (Volker) 3437 - fix configure script's cdrom detection on BeOS (Bryce) 3438 - fix physical CD change at runtime (Bryce) 3439 - cmos 3440 - fix panic when WinXP read port 70h (Christophe) 3441 - add ps/2 style century at index 37 to allow WinXP to boot. (Bryce) 3442 - dma 3443 - DMA register and unregister functions for DMA channels added and macros 3444 for DMA functions defined. The changes are based on the Plex86 functions. 3445 (Volker) 3446 - implementation of the DMA controller reset (Volker) 3447 - the value of the command register must be always 0x00 (BX_ERROR fixed) 3448 - floppy (Volker) 3449 - implemented Tape Drive Register (Dave Poirier) 3450 - added support for 360k floppy images 3451 - the skip flag (SK) in command 'read sector' is ignored now 3452 - floppy read and write function do not set the 'seek end' bit in status 3453 register 0 (fixes SF bug #553377) 3454 - the status of the 'disk changed' line depends on the selected drive. 3455 The digital input register is now an array (DIR[4]). 3456 - apply patch [ 635021 ] floppy cleanup by Alex Thiel 3457 - distinguish between floppy drive type and media type 3458 - hard drive 3459 - add largefiles support, to allow disk images larger than 2gig. 3460 (Stu Grossman) 3461 - missing conditions for lower_irq() added (Volker) 3462 - several noncritical panics replaced with BX_ERRORS and the controller 3463 returns an error code until we implement the features (Volker) 3464 - applied patch from Carl Sopchak for booting sco openserver 3465 - allow disk block access only if concatenated images are not used 3466 (Christophe) 3467 - fix bug [ 419415 ] netbsd 1.5 rescue disk won't boot (Volker) 3468 - multiple drq atapi data transfers corruption fixed (Christophe) 3469 - added some commands to the unsupported "Set Feature" commands (Christophe) 3470 - speedups in repeated IO transfers (Kevin) 3471 - support for Peter Tattam's external disk simulator (Bryce) 3472 - 4 channels / 8 devices support (Christophe) 3473 - "inquiry" atapi command results corrected (Volker) 3474 - check for incomplete devices configuration before starting the 3475 simulation (Bryce) 3476 - implemented the different bios disk translation schemes (Christophe) 3477 - keyboard and mouse 3478 - add commands 0xd2, 0xdd and 0xdf (Dave) 3479 - fix bug [ 613975 ] wxWindows: params redefined on restart (Bryce) 3480 - in function mouse_motion(): added parentheses to fix compilation problems 3481 with MSVC.

Now bioses for 1, 2, 4 and 8 processors 3528 are built at the same time (Bryce) 3529 - fixes to be able to compile the bios with gcc2 or gcc3 (Jeroen and 3530 Christophe) 3531 - changes on boot signature check (Christophe): 3532 - never done for cdroms 3533 - always done for hard-disks 3534 - conditional for floppies 3535 - add keyboard int16 functions 0x09 (get keyboard functionality) and 3536 0x0a (get keyboard id) (Christophe) 3537 - fix bug [ 629810 ] int 16/ah=01 broken? Enable interrupt on entering 3538 int16 handler (Christophe) 3539 - new keyboard init in POST (patch from Adam Sulmicki) 3540 - flush input and output keyboard buffer before keyboard self test 3541 (Volker and Christophe) 3542 - fix bug [ 547603 ] kbd up/down arrows in dos install (Christophe) 3543 - fix bug [ 549815 ] bios wrongly loads CS,ES. CS and ES are set to 0 3544 before the bootloader code is called. (Christophe) 3545 - PCI functions support (Volker) : 3546 - BIOS32 service directory 3547 - real mode PCI int1a functions 3548 - protected mode PCI int1a functions 3549 - fix reset for MS-DOS and Win95 (Volker) 3550 - 360K floppy support (Volker) 3551 - enhanced ata/atapi support (Christophe) : 3552 - 4 channels / 8 devices 3553 - device auto detection (with help from Adam Sulmicki) 3554 - EDD3.0 3555 - 32bits device access 3556 - optional disk translation "large", "r-echs" or "lba" (up to 8.4GiB) 3557 - re-enable harddisk controller interrupt after reads/writes. 3558 Win95 can now use native access to harddisks and cdroms. (Volker) 3559 - shutdown status handling (cmos index 0x0f) (Christophe) : 3560 - fix bug [ 601166 ] CMOS Problem @ "0x0F Index 0x05 data". After reset 3561 execution will resume by a jump to [0x40:0x67] if the shutdown status 3562 is 5 3563 - the bios don't panic any more if the shutdown status is 9 3564 - two parallel ports detection in POST (Volker) 3565 - two serial ports detection in POST (Volker) 3566 - add int15 extended memory function 0xe820 (patch from osmaker) and 3567 0xe801 (patch from Hartmut Birr) 3568 - fix return values on some int15 functions (Bryce) 3569 - fix int70 handler overlapping int08 handler (Christophe) 3570 - simplify 8 processors BIOS for operating systems which don't do 3571 paranoia/sanity checks (Zwane) 3572 3573- configuration interface 3574 - wxWindows config interface now allows you to change every bochsrc 3575 option using menus and dialog boxes. There is also the beginning of 3576 a wxWindows graphical debugger, but it needs a lot of work before it 3577 will be useful. 3578 - renamed control.cc to textconfig.cc. Now we're calling it a 3579 text configuration interface, instead of a control panel. 3580 3581- display libraries 3582 - Even though we've had them for years, the term "display library" is new in 3583 release 2.0. In the gui directory, Bochs has a number of different C++ 3584 files which you can select to display the text and graphics on the 3585 simulated monitor. Each of these is a display library. The display 3586 libraries are: 3587 x use X windows interface, cross platform 3588 win32 use native win32 libraries 3589 carbon use Carbon library (for MacOS X) 3590 beos use native BeOS libraries 3591 macintosh use MacOS pre-10 3592 amigaos use native AmigaOS libraries 3593 sdl use SDL library, cross platform 3594 svga use SVGALIB library for Linux, allows graphics without X 3595 term text only, uses curses/ncurses library, cross platform 3596 rfb provides an interface to AT&T's VNC viewer, cross platform 3597 wx use wxWindows library, cross platform 3598 nogui no display at all 3599 - it is now possible to compile Bochs with support for many different 3600 display libraries and select the one to use at runtime (even without 3601 plugins). See the display_library directive in .bochsrc. 3602 - add new svgalib display library by Igor Popik 3603 - fix bug [ 614724 ] SDL can get stuck in full screen mode 3604 display libraries such as SDL which have a full screen mode can be 3605 dangerous, if Bochs does not switch back to normal display mode at 3606 the right time. This is fixed for SDL and the new svga. 3607 - keymap support added in SDL interface (Bryce, Volker) 3608 - new keymap files: SDL keymaps for US and DE keyboards, X11 keymap 3609 for Danish keyboard. 3610 - use keyboard mapping for keyup messages too 3611 - renamed almost all references to data type "Boolean" to "bx_bool". 3612 The Boolean data type was defined in Carbon.h headers, and conflicted 3613 with Bochs's definition. See bug [ 618388 ] Unable to boot under MacOS X 3614 Exceptions: When talking to the Carbon library, you must use Boolean. 3615 Also, siminterface.h uses standard "bool" instead of bx_bool. 3616 - "User" button added in toolbar. It can send keyboard shortcuts to 3617 the guest OS. (Volker) 3618 - snapshot improvement and memory leak fixed (Volker) 3619 - testing framework, based on comparing screen content, added (Greg) 3620 - term display library: 3621 - support for color terminal, function keys, clear screen (Volker) 3622 - solaris compilation problem (bug #613393) fixed (Bryce) 3623 - win32 display library: 3624 - use native win32 toolbar for headerbar, use system palette (Volker) 3625 - many Carbon interface improvements: 3626 - patch [ 549248 ] Fix Carbon key & menu handling (Chris Thomas) 3627 - partial keymap support, copy&paste, menu items fixed, new toolbar 3628 behavior, dialog box display for panics (Br'fin) 3629 - sdl display library: 3630 - keyboard fixes and key mapping added (Bryce) 3631 - when captured, the mouse is forced to stay in the window. fix bug 3632 [ 619283 ] SDL: os mouse pointer leaves the window (Bryce) 3633 - x display library: 3634 - bug [ #537593 ] vga font not being found fixed. If vga font not 3635 found, search for a font called "-*-vga-*" (Bryce) 3636 - keyboard problems fixed (Bryce, Christophe) 3637 - beos platform, any display library: add a nice icon to the executable 3638 (Bernd Korz) 3639 3640- wxWindows 3641 - wxWindows is a cross-platform C++ user interface library which you can 3642 download for free at http://wxwindows.org. wxWindows provides C++ 3643 classes for all sorts of GUI controls (buttons, menubars, etc.) and 3644 implements all of them using the native controls on the platform. 3645 - The new wxWindows port of Bochs provides both a graphical configuration 3646 interface (for editing bochsrc options) and a display. It was 3647 written by Bryce Denney, Don Becker, Dave Poirier, and Volker Ruppert. 3648 - In release 2.0, we concentrated on making the wxWindows port as stable 3649 and functional as the other interfaces. wxWindows provides a great 3650 toolbox that we can use to make Bochs easier to learn and use. 3651 - wxWindows supports charmap changes, keyboard mapping, cut and paste, 3652 text and graphics modes, text mode cursor size, and mouse (Volker, Bryce) 3653 - To compile Bochs with wxWindows, you should install wxWindows 2.3.3 3654 or later. Then configure Bochs with --with-wx. 3655 - if you have multiple versions of wxWindows installed (e.g. a debug 3656 and a release version), you can set $WX_CONFIG before configuring 3657 to select between them. (Bryce) 3658 3659- Bochs debugger 3660 - [ 609616 ] remote GDB stub 3661 add GDB Stub support from Johan Rydberg, with bug fixes by Stu Grossman 3662 - add hooks for external debugger for win32. The external debugger 3663 that connects to Bochs is distributed in 3664 build/win32/tattam-external-debugger.zip in binary form. Turn on 3665 with --enable-external-debugger. (Peter) 3666 - add "debugger_log" option to bochsrc, which logs all debug output 3667 into a file. feature [ 629068 ] (Christophe) 3668 - debugger is now usable in fullscreen SDL and SVGA guis. It will 3669 switch back to text mode for each debug prompt (Bryce) 3670 - disassembly output cleaned up and improved 3671 (Kernel Panic, Peter Tattam, Jonathan Shapiro, Luiz Henrique Shigunov) 3672 - fix [ 628806 ] debug: x/c prints unprintable chars (Bryce) 3673 - add the beginnings of a wxWindows debugger. Not ready for mainstream use 3674 yet. CPU register display is implemented, and you can type any debugger 3675 command you want into the Debug Console window. (Bryce) 3676 - add help command (Alexander Krisak) 3677 - symbol table lookups cleaned up a bit (Bryce) 3678 - displays the address of the caught watchpoint, feature #435271 (Dave) 3679 - remove obsolete "loader" 3680 3681- utilities 3682 - fixed bug [ 487758 ] bximage fails on file creation >2048meg 3683 Bximage should now work up to 32gig. (Bryce) 3684 - on win32, both bximage and niclist now ask the user to press 3685 return before exiting, so that you have time to read the results 3686 before the window disappears. (Bryce) 3687 3688------------------------------------------------------------------------- 3689Changes in 1.4.1 (June 22, 2002): 3690 3691- now cdrom is enabled in configure, unless you specifically disable 3692 it with --disable-cdrom. (Christophe) 3693- fix compile error in main.cc when SMP or APIC is enabled (Dave) 3694- the runtime menu now displays 11 (continue) by default (Bryce) 3695- initialize DMA controller before floppy and SB16 3696- fix DMA panic when installing win95 (Volker) 3697- first character of the vga bitmap is blank on win32 (Volker) 3698 Before, it was incorrectly coded as a '@'. 3699- AltGr key on European keyboards works now on win32 (Volker) 3700- fix problem with console/serial port on Bochs exit (Volker) 3701- enable serial port for GNU and GNU/Linux (Volker) 3702- small documentation fixes (Volker) 3703- remove unnecessary include statements for X11 (Volker) 3704- italian keymap added (Emanuele Goldoni) 3705- fix win32 ethernet frames error. It will no longer reject packets 3706 that are less than 60 bytes long. (Peter Tattam) 3707- BIOS fixes : 3708 - win2k cd-boot (Christophe) 3709 - emm386 crash (Dave) 3710 - cs=0 at boot time (Christophe) 3711 - keyboard failure in scandisk (Dave) 3712- fix bug in forming the 64-bit APIC base address from two 32-bit registers. 3713 A compiler warning in cpu/proc_ctrl.cc pointed this out. 3714- fix default choice in the runtime options menu 3715 3716------------------------------------------------------------------------- 3717Changes in 1.4 (March 27, 2002): 3718- ROM BIOS 3719 - Boot from CDROM! Christophe Bothamy added partial El Torito support in 3720 rombios.c, which allows Bochs to boot cdroms. Booting from win2k or winXP 3721 cdrom is not supported yet. The default BIOS includes El Torito functions. 3722 the boot line must say "cdrom". 3723 Example: 3724 boot: cdrom 3725 - implementation of int13 diskette function 5 (format track) (Volker) 3726 - initialisation of PIC and DMA-2 added to POST code (Volker) 3727- configure script (Bryce Denney) 3728 - the configure script now detects your platform and provides a default 3729 GUI and the required compiler flags. All supported platforms should 3730 compile with simply "configure" and "make". 3731 - default guis by platform: 3732 - win32/windows/cygwin: win32 gui 3733 - MacOS X: carbon gui 3734 - MacOS 9 or earlier: macos gui 3735 - BeOS: beos gui 3736 - AmigaOS: amigaos gui 3737 - all other platforms: X windows gui 3738 - compile arguments supplied by configure script 3739 - win32: too many to list here; see documentation 3740 - cygwin: -mno-cygwin -DWIN32 3741 - MacOS X: -fpascal-strings -fno-common -arch ppc -Wno-four-char-constants 3742 -Wno-unknown-pragmas -Dmacintosh 3743 - the --with-GUINAME configure option is only needed if you want to override 3744 the default GUI. This is the only way to use the Term, RFB, and SDL 3745 GUIs. 3746- VGA 3747 - added VESA BIOS Extensions code by Jeroen Janssen (banked mode only, LFB 3748 support in patches) 3749 - vga memory read/write functions in text mode fixed 3750 - implementation of CGA mode 320*200*4 (patch from Sebastien Bechet) 3751- VGA BIOS 3752 - updated Christophe Bothamy's LGPL VGA BIOS to version 0.3a. This consists 3753 of a bug fix for function ah=13 and VBE support by Jeroen Janssen. 3754- networking 3755 - chipmem read/write limit fixed (Mike Lerwill) 3756 - writing a byte in 16-bit mode now possible (Mike Lerwill) 3757 - new ethertap interface for Linux, which allows Bochs to talk to 3758 the local machine and the internet (Bryce Denney) 3759 - NE2000 is now enabled by default on Win32, Cygwin, and Linux compiles 3760 in the .conf.* scripts and release binaries. 3761 - fix check for auto transmit disable, which was checking the wrong bit 3762 (Peter Tattam) 3763 - Win32 only 3764 - niclist.exe has been revised to work on more Windows versions, and it 3765 suggests a usable ne2k line (Dean Payne) 3766 - fix timeout setting so that ne2000 does not slow down the whole 3767 simulation (Don Becker) 3768 - bug fix: be able to handle multiple packets that arrive at once 3769 (Mike Lerwill) 3770- GUI changes 3771 - cdrom button: click this to notify Bochs when you changed the CDROM (Volker) 3772 - snapshot button: saves the text on the Bochs screen into a file called 3773 snapshot.txt (Volker) 3774 - copy button: on Win32 and X windows, copy the text on the Bochs screen 3775 to the clipboard (Volker) 3776 - paste button: on Win32 and X windows, paste the characters on the 3777 clipboard into the Bochs window. This requires keyboard_mapping to 3778 be enabled. (Bryce Denney) 3779 - improved text mode cursor for Win32, X11, and SDL (Volker) 3780 - new SDL interface (Dave Poirier, debugging by Christophe, Volker, Bryce) 3781 SDL is a graphics library that has works on many platforms. This interface 3782 is experimental, and is missing a few features of the standard Bochs 3783 interfaces: extended keys (arrows, keypad). 3784 - MacOS X: add MacOS X carbonized event handlers by Jeremy Parsons 3785 - X windows: when not enough colors can be allocated, force use of 3786 private colormap (Bryce Denney) 3787 - bug #490570 fixed: OUTB set and command 0xaa encountered (Dave Poirier) 3788- keyboard 3789 - completed keyboard emulation with the implementation of the three scancodes 3790 sets (mf1, mf2, mf3) with or without translation. This is based on Ludovic 3791 Lange's plex86 keyboard patch. (Christophe Bothamy) 3792 - added a "keyboard_type" option, that defines the answer to an "identify 3793 keybord" request to the keyboard controller. The available values are 3794 "xt","at","mf". (Christophe Bothamy) 3795 - added an optional keyboard_mapping option that enables to use your 3796 country specific keyboard with Bochs. If enabled, the keymap file must be 3797 specified in bochsrc. The available keymaps are US, German, Spanish and 3798 French for PCs running X11. Contributions are welcomed. (Christophe 3799 Bothamy) 3800 - added Windows(tm) key definitions (Volker Ruppert) 3801 - added paste button, which causes the emulated keyboard to type characters 3802 from the system clipboard. This only works when keyboard_mapping is 3803 enabled. (Bryce Denney) 3804- cdrom 3805 - bug fix: win32 could not read a cdrom image file 3806 - eject cd support for linux (patch from Petr Stehlik) 3807 - BeOS fixes 3808 - changing cdrom media is possible now with CDROM button 3809- sound blaster(tm) emulation (Volker) 3810 - you can use --enable-sb16=freebsd now 3811 - 16-bit DMA controller added 3812 - 16-bit mode of the SB16 implemented (output to file works) 3813- floppy drive (Volker Ruppert) 3814 - implementation of the floppy command 'format track' 3815 - implementation of read / write operations with MT=0 3816 - behaviour of a few floppy commands fixed 3817 - floppy reset behaviour fixed 3818 - lots of other fixes 3819- fixed bug [ #468340 ] pic:slave: OCW3 not implemented. Now the slave PIC 3820 supports all the modes that the master PIC does, and nobody will see this 3821 message again. 3822- serial port (by Volker Ruppert unless noted) 3823 - improved IRQ handling 3824 - now Windows 95 serial driver works correctly 3825 - fixed the return value of the MCR (loopback bit) 3826 - interrupt reasons LSR change and MSR change implemented 3827 - the number of data bits is considered when sending data 3828 - all serial port changes are tested in loopback mode only 3829 - serial port emulation fixed for FreeBSD and OpenBSD (Stu Grossman) 3830 - fix receiver poll frequency so that it doesn't slow emulation (Stu Grossman) 3831- Bochs debugger 3832 - when tracing, print the instruction just before it is executed, instead 3833 of just after (Greg Alexander) 3834 - after a triple-fault panic, you can now return to the debugger 3835- symmetric multiprocessor (SMP) simulation 3836 - no more panic if you read the EOI register 3837 - fixed default destination format in local APIC 3838 - fix SMP instruction tracing in bochs debugger 3839 - fix deadlock when debugger enabled and all processors HLT 3840 - MSR support added by Zwane Mwaikambo 3841- simulation of interrupts is more accurate (Volker) 3842 - implemented edge triggered interrupt mode 3843 - added functions raise_irq() and lower_irq() 3844- programmable interrupt timer (Greg Alexander) 3845 - fixed the PIT gate and improved the PIT printing options 3846 - experimental real-time PIT 3847- parallel port improvements (Volker Ruppert) 3848- bug fix: hard disk errors caused by overflowing imul in the BIOS code. 3849 Sebastian Bechet and Peter Tattam tracked it down and fixed it. 3850- fix some memory leaks (patch from Darko Tominac) 3851- Double-Word IO is supported for ATA devices 3852- fix bash-specific syntax in install-x11-fonts script 3853- print stack_return_from_v86 error only the first 100 times 3854 3855------------------------------------------------------------------------- 3856Changes in 1.3 (December 10, 2001): 3857- networking works on Windows and Linux platforms 3858- emulated cdrom can now read from ISO image files, on any platform. 3859- new PIT model by Greg Alexander which is much more complete than the 3860 old one. The new PIT is used by default, but you can switch back to 3861 the old one if you configure with --disable-new-pit. 3862 (PIT = 8254 programmable interrupt timer) 3863- new configuration menus by Bryce Denney, which allow you to change any 3864 bochsrc option using text menus, then save the configuration into 3865 a new bochsrc file for later use. You can disable the new code using 3866 configure --disable-control-panel. Also you can use the command 3867 line arguments -nocp or -nocontrolpanel. Also, there is a new 3868 "Config" button on the GUI that allows limited changes to the 3869 configuration at runtime, such as changing the floppy disk. 3870- add docbook documentation directory in the sources under doc/docbook. 3871 The transition from HTML to docbook documentation is still in progress. 3872- Add new log action "ask", as shown in these example bochsrc lines: 3873 panic: action=ask 3874 error: action=ask 3875 When an event occurs which is set to "ask", you get a beep and message 3876 on the text terminal that asks what you want to do. Choices are: continue, 3877 continue and disable future messages from this device, quit immediately, 3878 or segfault (where abort() function is available). If compiled with 3879 --enable-debugger, you can also choose to enter the debugger. 3880- Parallel port emulation cleaned up by Volker Ruppert. See .bochsrc for 3881 syntax of new parport1 line in bochsrc. 3882- PCI support improved by Volker Ruppert, including BIOS changes. Still 3883 not complete. 3884- floppy controller returns a proper error response if you try to write 3885 a read-only disk image. For systems such as DOS that actually use the BIOS 3886 services, it was also necessary to add code in int13_diskette_function to 3887 recognize a write-protected error and return the correct error status code 3888 (AH=3, Carry Set). 3889- the ROM BIOS now prints panic messages to the console. Thanks to Cliff 3890 Hones for his console display code. 3891- the ROM BIOS detects nonbootable disks (Barry Allard), and prints a message 3892 on the console. Barry Allard's patch who helped with checking the boot 3893 signature. 3894- LBA support added for hard disks. (Not tested very much.) 3895- add dependencies to makefiles 3896- logging code moved into a separate file, logio.cc 3897- new option --enable-slowdown-timer, by Greg Alexander, which kicks in if 3898 Bochs simulation time starts to run faster than real time. This helps to 3899 keep the Bochs clock in sync with the real clock when the CPU is mostly 3900 idle. 3901- new option --enable-iodebug, by Dave Poirier, which creates an I/O 3902 interface to the debugger. This lets you write software to be emulated 3903 in Bochs which can turn on instruction, register, or memory tracing 3904 using I/O accesses. 3905- improved detection of readline in configure script 3906- configure substitutes the version number into many files, instead of 3907 using sed in the makefile. There are still a few uses of sed remaining. 3908- you can now use environment variables in bochsrc values. For example, 3909 diskd: file="$BOCHS_IMG/diskd.img", cyl=615, heads=6, spt=17 3910- configure with --prefix=PATH works now 3911- running configure from a different directory works now, thanks to 3912 a patch from Edouard G. Parmelan 3913- fix [ #433759 ] virtual address checks can overflow. 3914 > Bochs has been crashing in some cases when you try to access data which 3915 > overlaps the segment limit, when the segment limit is near the 32-bit 3916 > boundary. The example that came up a few times is reading/writing 4 bytes 3917 > starting at 0xffffffff when the segment limit was 0xffffffff. The 3918 > condition used to compare offset+length-1 with the limit, but 3919 > offset+length-1 was overflowing so the comparison went wrong. 3920- cmpxchg8b patch from Michael Hohmuth <hohmuth@innocent.com> 3921- apply patch from Thomas Fitzsimmons <fitzsim@cygnus.com> to fix compile 3922 problems when BX_SUPPORT_PAGING and BX_USE_TLB are turned off 3923- fix bug introduced in 1.2.1 which caused spurious exceptions. 3924 See patch #439314, Exception 1 (debug) on HALT, from 3925 thomas.petazzoni@meridon.com. 3926- add panic in ctrl_xfer32.cc where the IRET32 implementation is broken. 3927 This only happens if you are NOT in vm8086 mode or protected mode. 3928 The intent is to warn people when they are getting bad emulation, and 3929 encourage people to report how they got to that point. 3930- apply patch from Santiago Bazerque. See this bug report: 3931 [ #463018 ] retf not removing parameters sometimes 3932- fix bug [ #461730 ] IRETD causes problems if NT-flag is set 3933 reported by Peter Lammich. 3934- apply patch [ #455014 ] CR0 bug in 80486, described as: 3935 > In the register CR0, when the bit PM is enabled, the bit 4 is 0 3936 > when should be 1. 3937- apply patch from Mike Rieker <mrieker@o3one.org> associated with this bug 3938 report: [ #480422 ] gdt 'accessed' bit 3939- in task_switch when it tried to ensure that the old TSS was paged in, 3940 it actually used the new TSS address, fixed. 3941- updated the instrumentation code, and added a working example. To try 3942 it, configure --enable-instrumentation=instrument/example1. Then when 3943 you run bochs, you will get one line for each instruction PC and for 3944 each I/O access in a new file called bxevent.txt. 3945- set a bit in the CMOS that says the processor has an FPU. This is 3946 from patch [ #455006 ] Device byte is not initialized aptly. 3947 Author did not leave their name. 3948- add logging code to the "null ethernet" which does not require host OS 3949 support. All this does is print the outgoing packets from the guest OS. 3950- cleanup of log functions (Todd Fries) 3951- add BX_ERROR for every command in ATAPI-6 that bochs does not support. 3952 I still need to do add some commands from older specs that are obsolete 3953 (and not listed) in ATAPI-6. Commands that aren't in the spec will still 3954 panic. 3955- only put 0xf into the 2nd hard disk field when the cdrom is not present. 3956 This is a patch from Volker Ruppert <Volker.Ruppert@t-online.de>, who 3957 comments: "The fdisk command reports an unusable second harddisk if the cdrom 3958 is enabled. This patch helps, but I don't know if it is the right way." 3959- make hard disk code return error codes when data is not available instead 3960 of just panicing. In particular, if the logical sector is out of bounds 3961 or the disk image cannot be read/written at the desired offset, we now 3962 abort the ATA command and return an error code. Many of the old BX_PANIC 3963 messages are turned to BX_ERROR, so they will still appear in the 3964 log, but now the device model will try to communicate this fact to 3965 the OS instead of simply giving up. 3966- don't blindly reject odd length atapi commands. There are cases when 3967 it's really ok according to ATA-4. 3968- for big endian machines, reversed the bit fields in interrupt_reason. 3969 This was pointed out by Nicholai Benalal. 3970- extended keyboard improvements by Dave Poirier 3971- major mouse patch from Dave Spring, that implements several missing 3972 mouse modes. 3973- commit keyboard patch from David Haslam <dch@sirius.clara.co.uk> 3974 posted to mailing list, that addresses the problem of each key press 3975 printing ^@. See cvs log for details. 3976- mouse performance fixes by Greg Alexander and Robb Main 3977- NE2000 fixes by Frode Vatvedt Fjeld, ecelca@yahoo.com, Greg Alexander, 3978 and angelos@openbsd.org. 3979- fix bug [ #468340 ] pic:slave: OCW3 not implemented. Some event handling 3980 code appeared in the master pic but not the slave pic. 3981- fix compile problems in SB16 code, related to fpos_t being treated as 3982 an integer. 3983- patch from Volker Ruppert <Volker.Ruppert@t-online.de> to fix 3984 midi output file so that winamp can play it. 3985- some cleanup of serial code by Todd Fries and Volker Ruppert, but it 3986 doesn't work yet. 3987 3988X Windows specific: 3989- commit patch from David Haslam <dch@sirius.clara.co.uk> 3990 [ #455763 ] Cursor trail with DOS Edit/Minix vi 3991- error for missing fonts now points to the documentation 3992- new option --enable-idle-hack, by Roland Mainz, which makes Bochs more 3993 friendly toward other processes when its CPU is idle. Presently, 3994 this option is specific to X windows. 3995 3996Win32 specific: 3997- now Windows 95/98/ME can read the physical cdrom (Don Becker) 3998- The default configuration for Win32 VC++, given in .conf.win32-vcpp, 3999 now enables the NE2000 and renames all .cc files to .cpp. This keeps VC++ 4000 happy but may make it hard to use CVS. 4001- The default configuration for Cygwin, given in .conf.win32-cygwin, now 4002 enables cdrom and SB16. 4003- See "new docs" on the web site for compile instructions for VC++ and Cygwin. 4004- The sources include a VC++ workspace, in addition to the old "nmake" 4005 makefile. 4006- ethernet support (emulated NE2000 card), coded by Don Becker. This 4007 implementation requires a library called WinPCap, which you can 4008 download from http://netgroup-serv.polito.it/winpcap. 4009- new utility called niclist.exe which lists the ID number of all your network 4010 cards (well probably you just have one). The ID be used when setting up your 4011 .bochsrc. 4012- patch [ #466403 ] make text colors more accurate. The author did not leave 4013 his/her name. 4014- fix GUI bug [ #452159 ] win32: mouse stuck if bochs win partly off screen 4015 Now we center the mouse periodically, whether or not the mouse has 4016 wandered outside of the window or not. 4017- event handler recognizes the extended keycode flag 4018- fixes for raw floppy and floppy disk images (Don Becker) 4019 4020Linux specific: 4021- Ethernet (emulated NE2000 card) now works in Linux! Contributed by 4022 splite@purdue.edu. This has been tested using host OS kernel 2.2.14, and 4023 works with telnet, ftp, irc, lynx, etc. Because it is a packet filter 4024 solution, you aren't able to talk to the host machine, only to other 4025 machines on the network. 4026- The default configuration for Linux, given in .conf.linux, now enables 4027 the NE2000 model. 4028- RPM build process configures with --prefix=/usr so that everything is 4029 installed in /usr/bochs instead of /usr/local/bochs. 4030- DLX Linux disk image is now installed so that only root can write it, to 4031 avoid security problems. When you run the bochs-dlx script, it creates a 4032 local copy in your home directory and then runs it. 4033- code that determines the capacity of a cdrom now works for both ATAPI 4034 and SCSI drives (splite@purdue.edu) 4035- applied patch from bochs@sigint.cs.purdue.edu. The comments are: 4036 > The Linux 2.4.5 CD-ROM driver sends a READ_DISC_INFO command which caused 4037 > an "unrecognized ATAPI command" panic. Looks like READ_DISC_INFO is only 4038 > recognized by CD-R and CD-RW drives, so I ignore it for now. 4039 4040Amiga MorphOS specific: 4041- Bochs now compiles and works on Amiga MorphOS. Configure with 4042 --with-amigaos. For AmigaOS only, see .bochsrc for use of fullscreeen and 4043 screenmode options. The Amiga MorphsOS is written and maintained by 4044 Nicholai Benalal <nicholai@chello.se>. 4045- raw cdrom supported if you configure with --enable-cdrom 4046 4047BeOS specific: 4048- Bochs compiles and works on BeOS. Configure with --with-beos. 4049 Bernd Thorsten Korz <bernd.korz@insidebeos.de> maintains the BeOS port. 4050- raw cdrom supported if you configure with --enable-cdrom 4051 4052MacOS X specific: 4053- Bochs now compiles and works on MacOS X. Configure with --with-carbon. 4054 Emmanuel Mailliard <e.rsz@libertysurf.fr> ported the Macintosh code to the 4055 Carbon API. 4056- The MacOS X application is built using (gasp) mkdir, copy, and rez. 4057 Surely this is not the right way, but it works. 4058- raw cdrom supported if you configure with --enable-cdrom 4059 4060RFB mode: 4061- apply patch.rfb-mouse by MURANAKA Masaki (monaka@users.sf.net) 4062 see this source forge bug [ #457968 ] Strange mouse motion on RFB 4063- add a retry loop in RFB code, so that if port 5900 is not available 4064 it can try 5901, etc. 4065 4066Bochs Debugger: 4067- do a vga update whenever you print a debugger prompt. 4068- added debugger command "info fpu" that prints the FPU registers. If you 4069 do "info all" you get cpu and fpu registers. 4070- added debugger command "info ne2k" which prints all the registers 4071 of the NE2000 model 4072- add ability to do register tracing and flag tracing (Dave Poirier). 4073 Try the trace-reg-on and trace-reg-off commands. 4074- instruction trace now includes time ticks 4075- fixed problems in which bochs compiled with debugger measured time 4076 differently from bochs compiled without debugger. Also when instruction 4077 trace was enabled, breakpoints and control-C did not work. Also, 4078 breakpoints at the beginning of an interrupt handler did not work. 4079 4080------------------------------------------------------------------------- 4081Changes in 1.2.1 (June 12, 2001): 4082- more work on makefile for building RPMs 4083- [ #432382 ] build debian packages patch 4084 add build/debian directory from Rob Lemley <rjlemley@calypsoblue.org> 4085 which allows us to make Debian packages! 4086- optimize for speed when simulating one processor. Now 1-processor 4087 performance should be equivalent to 1.1.2. 4088- [ #425640 ] sb16 assumes fpos_t is long int 4089 This fixes compiles of iodev/sb16.cc on linux systems with newer libraries 4090 in which fpos_t is not an integer. 4091- [ #432488 ] SMP:assert "n_logfn < MAX_LOGFNS" fails 4092 increase MAX_LOGFNS since we ran out of them on an SMP simulation with 4093 4 processors 4094- changes to compile clean on cygwin: 4095 - don't use the WIN32 snprintf define for cygwin 4096 - add ssize_t definition for cygwin 4097 - only compile "struct timeval tval" if select is available 4098 on that platform. 4099- [ #432491 ] SMP: CPUID says no APIC feature 4100 clean up inconsistent use of BX_SUPPORT_APIC and BX_APIC_SUPPORT, which 4101 caused the CPUID to report no APIC was present 4102- [ #431025 ] --enable-external-device-models broken 4103 removed configure options for external-device-models and 4104 external-cpu-memory. These don't work and aren't going to be fixed. 4105- [ #429448 ] configure: -lreadline when not there 4106 Now configure allows you to choose not to use readline, even if it's found 4107 on your system. 4108- [ #428915 ] apply extended keyboard patch 4109 extended keyboard patch by Dave Poirier <eks@void-core.2y.net> 4110- [ #428626 ] if no X11 found, configure&make fails 4111 Now configure halts if X windows is selected but no X libraries are found. 4112- updated rombios to version 1.13. This fixes several problems: 4113 - [ #430472 ] DOS HIMEM "A20 line" error 4114 This problem was apparantly caused when Bryce added a function that prints 4115 the BIOS version, and he called it too early in the boot process. Now the 4116 same function is called later, and it doesn't break the A20. 4117 - [ #431010 ] SMP structure overwritten in v1.2 4118 SMP structures were getting overwritten by BCC-generated data, 4119 preventing SMP operating systems from detecting that other processors 4120 were available. 4121 - [ #431016 ] bios: SMP struct has wrong entry count 4122 SMP structure had the wrong entry counts 4123- very minor doc updates (typos, replace broken link to mtools info) 4124- quit when the user clicks the power button, even if they have disabled 4125 panics. 4126- win32 now defaults to having mouse capture mode turned off. For new users, 4127 it would be distressing for their mouse cursor to disappear until they 4128 pressed F12. 4129- [ #428222 ] vga font not installed 4130 added script called "install-x11-fonts" which should help people install 4131 the VGA font on X windows systems, if it isn't already there. 4132 4133------------------------------------------------------------------------- 4134Changes in 1.2 (June 3, 2001): 4135- [ #427259 ] rombios HALT calls don't print 4136 Fixed bios/rombios.c HALT macro so that it writes the line number of the 4137 panic to the PANIC_PORT (port 0x400) and then does NOT do a halt 4138 instruction. Also changed iodev/unmapped.cc so that the line number written 4139 to PANIC_PORT is displayed as a BX_PANIC message. Because the HALT 4140 macro now triggers the normal panic behavior, it can be controlled by 4141 the bochsrc. 4142- [ #429016 ] crash if no hard drive 4143 rombios used to call HALT macro if no hard drive was found. Now it only 4144 calls HALT if a hard drive has an illegal geometry. 4145- [ #425388 ] include source for simple disk img tool 4146 [ #428478 ] mkimg tool creates image 1 byte too big 4147 Added bximage tool, which makes empty floppy and hard disk images. 4148 It is now included in the top level Makefile, so it will get built 4149 by default on all platforms. 4150- [ #426036 ] eth_fbsd.cc compile problem on solaris26 4151 added configure test so that "configure --enable-ne2000" only 4152 includes the Berkeley Packet Filter code (eth_fbsd) if the header 4153 file <net/bpf.h> can be found. If you don't have BPF the ne2000 4154 will not actually move packets, but at least it will compile clean now. 4155- [ #428214 ] 1.2.pre1 need documentation for binaries 4156 Write windows and linux specific documentation to be installed in 4157 binary releases. 4158- [ #429258 ] disable RESET for version 1.2 4159 Since soft reset was not completely working, I reverted the reset patch. 4160 Now it does panics on reset instead of trying to reboot, as the old 4161 bochs versions did. 4162- [ #428222 ] Should the linux RPM install vga font? 4163 now font/vga.pcf will be installed in the RPM package 4164- [ #429020 ] stop renaming the BIOS!!! 4165 new BIOS changes are now in BIOS-bochs-latest, instead of a BIOS 4166 whose name changes every time we change anything! To help distinguish 4167 different BIOS versions, the BIOS now prints its RCS Id into the 4168 log file. 4169- [ #428625 ] compile problem if SHOW_IPS is on 4170 removed extra paren that broke SHOW_IPS 4171- [ #428219 ] PCI doesn't compile with SMF=1 4172- [ #429375 ] pthreads detection broken 4173- [ #429073 ] configure: if no X11, makes bad config 4174- [ #429229 ] install current .bochsrc in binary rels 4175- install Tim's man pages on linux RPM 4176- BIOS prints messages in log in case of boot failure 4177- rewrote instructions for compiling in win32 (win32.txt) 4178- fixed link in HTML changelog.html to point to the real sources on SF. 4179- added missing LOG_THIS definition to gui/nogui.cc and gui/rfb.cc 4180- added additional check for null pointer in debugger exit routine 4181- added diskd to .bochsrc 4182 4183------------------------------------------------------------------------- 4184Changes in version 1.2-pre1 (May 25, 2001): 4185- major cleanup of .bochsrc 4186- major cleanup of stderr output: prints bochs version information when 4187 starting, and at the end it tries to print the message that caused 4188 bochs to quit. 4189- two hard disk support (diskd). At present, you cannot have two 4190 hard drives and a cdrom at the same time, because there is only 4191 one IDE controller with two channels. 4192- split hard disk support allows different partitions to be stored in 4193 different image files 4194- two new GUI choices: term mode and RFB mode. Term is a text-only 4195 interface, and RFB creates a server that can be accessed using 4196 the AT&T VNC viewer. 4197- now Bochs can simulate an SMP machine, if you configure with 4198 --enable-processors=N. Configuring more than one processor has 4199 a major performance impact, so the default is 1 processor. 4200 See SMP documentation for more details. 4201- to make SMP work, bx_mem and bx_cpu have been replaced with 4202 bx_mem_array[] and bx_cpu_array[]. The cpus are referenced through 4203 the BX_CPU(n) macro and memories through the BX_MEM(n). Normal 4204 mode has one cpu and one memory, SMP mode has multiple cpu's and 4205 one memory, cosimulation mode has multiple cpus and multiple memories. 4206- use --enable-cpu-level=6 to make Bochs claim to be a Pentium Pro. 4207 The only feature that requires CPU level 6 is apic support. 4208- new logging system by Todd Fries, which has 4 levels of event 4209 severity (panic, error, info, debug). There are new .bochsrc 4210 options that control what action to take when a 4211 panic/error/info/debug event occurs. 4212- now searches for .bochsrc, bochsrc, bochsrc.txt, and (on unix only) 4213 $HOME/.bochsrc. 4214- use GNU readline library if --enable-debugger is on, as long as readline 4215 can be found on the machine 4216- configure checks for existence strtoull and strtouq. if neither exists, 4217 Bochs uses its own implementation 4218- applied patches from Cliff Hones <cliff@aonix.co.uk> to fix up the 4219 rombios. This includes many improvements, which you can list by 4220 doing "cvs log -r 1.6 bios/rombios.c" or looking at cvsweb. 4221- added suggested geometries of larger disks to the documentation 4222- this is the first release to have official binary packages for win32 4223 and Linux. There is a new "make rpm" in the top-level Makefile which 4224 will create an RPM of the current bochs directory. To use this, 4225 become root and type "configure; make rpm". 4226- applied some FreeBSD patches from Maxim Sobolev (cdrom and serial). 4227 4228------------------------------------------------------------------------- 4229Changes in version 1.1.2 (bugfix3, May 16, 2001): 4230- updated Elpin VGA BIOS to version 2.40, and changed pointer in .bochsrc 4231- fixed .conf.x86 script so that it uses c++ instead of egcs for C++ files 4232- now Makefile targets that recurse into subdirectories use double colons, 4233 so that it will always recurse into subdirectories. Now a single make 4234 command should notice a modified source file in a subdir. 4235- fixed bug in bx_panic. If BX_PANIC_IS_FATAL==0 and a (non-fatal) panic 4236 occurs, it used to call bx_atexit() and then return. It should never 4237 call bx_atexit, which starts to shut down the simulator, unless it's 4238 really going to quit! 4239- support 2.88 MB floppy disks 4240- since dataseghack is checked in as non-executable, invoke it with 4241 "csh dataseghack" 4242- double fault patch from Thomas Petazzoni <thomas.petazzoni@ifrance.com>, 4243 sourceforge patch #423726. 4244- removed -fno-builtin from fpu makefiles 4245- redefine u_char, u_short, etc. in order to not conflict with system 4246 definitions of these same types. 4247- in cdrom.cc, remove the extern "C" { } structure around some of the 4248 header files. This is no longer necessary. 4249- do not panic on hard disk command 0x1f2 (read sector count) 4250- in keyboard.cc: 4251 - apply Todd Fries' reset patch 4252 - recognize most of the "Grey" insert/delete/home/end/etc. keys the 4253 same as keypad keys. 4254 - removed panic on "kbd_ctrl_to_kbd(): got value of 0x??" 4255 - implement mouse command 0xf6 (set defaults) 4256- apply Suboner@aol.com's Xwindows timing patch from 4257 http://sourceforge.net/tracker/index.php?func=detail&aid=418730&group_id=12580&atid=312580 4258- remove all patches from patches subdir which have already been applied. 4259 The remaining ones are under consideration but not applied. 4260 4261------------------------------------------------------------------------- 4262Changes in version 1.1.1 (bugfix2, April 9, 2001): 4263- in soundwin.cc, arg 3 should be typecast to LPWAVEFORMATEX 4264- in fpu_entry.c, Bryce mistyped his own initials! 4265- in configure.in and configure, define good defaults for VC++ 4266 #define BX_64BIT_CONSTANTS_USE_LL 0 4267 #define inline __inline 4268 #define BX_NO_EMPTY_STRUCTS 1 4269 #define BX_NO_ATTRIBUTES 1 4270 #define BX_HAVE_HASH_MAP 0 4271- in config.h.in, fixed typo in #error message 4272 4273------------------------------------------------------------------------- 4274Changes in version 1.1 (bugfix1, April 6, 2001): 4275 4276(FIXED, patch #414360: update copyrights) 4277update headers. Change copyright to 2001, replace config.h.in header with 4278the standard mandrake header that every other file uses. 4279 4280(FIXED, patch #414356: inlines) 4281make macro to replace inline and static/extern keywords. Then make 4282define the macro appropriately based on configure. 4283 4284(FIXED: patch #414234: macos-no-strdup) 4285--with-macos should force HAVE_STRDUP=0. 4286 4287(FIXED, patch #403027: Fix mouse bugs in Linux and BSD) 4288Linux and BSD (maybe others) cause panic in mouse code. 4289 4290(FIXED, patch #413851: const64bit patch) 4291VC++ does not allow "LL" after 64-bit constant. 4292 4293(FIXED, patch #413859: fabs symbol conflict) 4294fpu code contains fabs, which conflicts with math library fabs. 4295 4296(FIXED, patch #403004: Implement aborts on a few SET FEATURE commands...) 4297Implement aborts on a few SET FEATURE commands for ATA. 4298 4299(FIXED, patch #402991: Update to iodev/vga.cc to add 3c3h read support) 4300Implement VGA enable register, at 0x3c3. 4301 4302(FIXED, patch #403027: Fix mouse bugs in Linux and BSD) 4303Mouse panic in linux/BSD: 4304KBD: io write 0x64: command = 0xD3(write mouse outb) 4305 4306(FIXED, patch #414229: panic-is-fatal) 4307Allow user to decide if panic is fatal, or just a warning 4308 4309(FIXED, patch #414230: sun-cdrom) 4310Support Sun CDROM 4311 4312(FIXED, patch #413574: portable1) 4313there are cases where a pointer is cast to a 32-bit int, 4314then later cast to a pointer and dereferenced, which crashes any 64-bit 4315machine. 4316 4317(FIXED, patch #413574: portable1) 4318some machines have no snprintf or strtoull. include a replacement function 4319when needed. 4320 4321(FIXED, patch #413574: portable1) 4322Some compilers don't allow "typedef struct { } foo;" 4323 4324(FIXED, patch #413574: portable1) 4325Some people don't have hash_map.h, used in dbg_main.cc. Disable this code 4326if hash_map.h not found. 4327 4328(FIXED, patch #413574: portable1) 4329Some compilers can't handle labels at the end of a block, as in 4330 void main () { /*code*/ label: } 4331 4332(FIXED, patch #413574: portable1) 4333Most compilers can't handle __attribute__. Use macro to define it away. 4334 4335(FIXED, patch #413574: portable1) 4336if --enable-debugger, turn on --enable-disasm too. 4337 4338(FIXED, patch #413574: portable1) 4339ome compilers can't handle any chars after an #endif 4340 4341(FIXED, patch #413574: portable1) 4342wrong type arg1 of bx_dbg_watch and bx_dbg_unwatch.

This struct was never 4356used by bochs anyway. 4357 4358(FIXED, patch #414046: portable2) 4359move definition of missing library functions into osdep.h and osdep.cc, 4360include contents of macutils*. 4361 4362(FIXED, patch #414061: win32-rawcd) 4363CDROM drive letter for WIN32 should not be hardcoded. 4364 4365(FIXED, patch #414060: win32-rawfloppy) 4366Bypass fstat when opening WIN32 raw floppy disk. 4367 4368(FIXED, patch #414226: pit-panic) 4369WinME install dies with panic: 4370bochs: panic, pit: outp(43h): comm Bh, mode 00, bcd 00 unhandled 4371I think I had a similar problem.
