Hardware Support 4.3BSD tahoe release of June 1988 .AU .AI Computer Systems Research Group Department of Electrical Engineering and Computer Science University of California, Berkeley Berkeley, California 94720
Tahoe Hardware support in the 4.3BSD tahoe releaseThe system runs on the Computer Consoles, Inc. Power 6/32 processor, known as ``tahoe.'' The distribution supports the following machines:
Any of the standard CCI-based disk controllers (VDDC or SMD, SMD-E and enhanced SMD-E with scatter-gather I/O support) may be used. The following disks are known to work; others may be used by creating new disk labels, but might not allow initial bootstrapping: CDC FSD (160 MB), CDC 9766 (300 MB), CDC XFSD (340 MB), CDC 515MB, Fujitsu 360 MB, Fujitsu Eagle (440 MB), and Maxtor 340Mb.
The VIOC-X and MPCC controllers are supported for asynchronous serial communications.
The ACC (ace) and CMC (enp) Ethernet controllers are supported.
The only tape controllers currently supported are the Ciprico Tapemaster F880 and M990 controllers, normally used with Cipher 1/2" magnetic tape drives.
VAX Hardware support in the 4.3BSD tahoe releaseThe system runs on VAX-11/725, VAX-11/730, VAX-11/750, VAX-11/780, VAX-11/785, VAX-8200, VAX-8250, VAX-8600, and VAX-8650 processors and supports the standard DEC mass storage peripherals: RM03, RM05 RP06, RP07, RA60, RA70, RA80, RA81, RA82, RM80, RL02, and RK07 disks; TS11, TU80, TE16, TU45, TU77, TU78, and TU81 tapes. MicroVAX II processors and workstations are supported, including QVSS and QDSS displays (VSII and VAXStation/GPX), RQDX2/3 disk controllers with RD52, RD53 and RD54 disk, and TK50 or other standard tape. DEC standard bad block handling is supported on all the DEC disk drives except the RL02.
The EMULEX SC21-V and SC31 UNIBUS storage module disk controllers are supported with AMPEX 9300 and CDC 9766 300 Megabyte disk drives, AMPEX Capricorn 330 Megabyte Winchester disk drives, FUJITSU 160 Megabyte Winchester drives. In addition, the SC31 supports FUJITSU Eagle 404 Megabyte Winchester drives. Other drives may be supported by addition of table entries to the driver, although a listed drive is required for initial bootstrapping. The EMULEX SC750 (emulating the DEC RH750 MASSBUS interface) and the SC780 and SC7000 series disk controllers (emulating the DEC RH780 MASSBUS interface) are supported with the CDC 9775, 9766, and 9730 disk drives, AMPEX 9300 and Capricorn disk drives, and the FUJITSU Eagle 404 Megabyte Winchester disk drive. Additional drives may be supported by creation of a new entry in the disktab (4) file followed by installation of a disk label on the drive using disklabel (8). Bad blocking support is provided on all disks attached to an EMULEX UNIBUS or MASSBUS controller.

The EMULEX TC-11 tape controller (which emulates a TM11 DEC UNIBUS controller), the EMULEX TC-7000 tape controller (which emulates a TU77 DEC MASSBUS controller), and System Industries Model 9700 tape drive (which emulates a DEC TU45 controller on the UNIBUS) are supported. Other controllers which emulate supported DEC tape controllers should also work.

To bootstrap the system, a supported disk and tape drive are needed. To maintain all the system sources and binary programs, at least 120 Megabytes of disk storage is required.
For terminal interfaces, the standard DEC DZ11, DMZ32, DHU11, DHV11 and DMF32 terminal interfaces are supported. In addition, DH11 emulators such as the ABLE DH/DM (which replaces the ABLE DMAX) and EMULEX CS-11 and CS-21 are supported. The system also provides support for standard line printer interfaces emulating the DEC LP11 or the parallel port of the DMF32. Support for serial printers such as a DECwriter-III and printer-plotters such as those made by BENSON/VARIAN or VERSATEC is available with standard drivers.
This release supports any number of any of the devices described above. The devices may be placed arbitrarily on any available MASSBUS and UNIBUS interfaces. For the 8600 and the 8650, adapters may be on either of the SBIA's. The system configures at boot time, locating available devices, using a system configuration compiled into the kernel. The configuration description contains all the information about the topology of the machine and the addresses at which the various devices are located. It is possible (and desirable) to write the description using ``pattern matching'' to only partially specify some of the interconnects. The bootstrap passes the identity of the load device to the kernel, which will use it as the root file system. .KS

The system configuration program sizes system data structures based on a specification of the maximum number of active users to be present on the system. To build a system for a larger or smaller workload you only need change this single constant. The system also initializes the parameters to the paging system and sizes its file system buffer cache based on the amount of available memory.
The system supports access to the 11/780 and 11/785 console floppy disk, the 8600 and 8650 RL02 console disk drive, and the 11/725, 11/730, and 11/750 TU58 console cassette tape. However, reliable access to the 11/750 TU58 cassette interface is possible only on a totally quiescent system.
