68otherwise they attach at 69.Nm isa . 70.Pp 71Note that interrupt mappings on the i386 may require that the BIOS 72be configured to reserve the interrupts for these devices as "Legacy ISA". 73If such configuration is not done, the system may use those interrupts 74for 75.Xr pci 4 76or 77.Xr isapnp 4 78devices instead. 79.Pp 80.Ox 81provides support for the following devices. 82Note that not all architectures support all devices. 83.Ss SCSI controllers 84.Bl -tag -width 12n -offset ind -compact 85.It Xr aic 4 86Adaptec AIC-6260 and AIC-6360 SCSI interface 87.It Xr uha 4 88Ultrastor SCSI interface 89.It Xr wds 4 90WD7000 compatible ISA SCSI interface 91.El 92.Ss Disk and tape controllers 93.Bl -tag -width 12n -offset ind -compact 94.It Xr fdc 4 95NEC765 compatible floppy disk driver 96.It Xr wdc 4 97Standard Western Digital type hard drive controllers: MFM, RLL, ESDI, 98and IDE/ATAPI. 99See also the 100.Xr pciide 4 101device driver which is used instead on machines with PCI IDE controllers. 102.El 103.Ss Serial and parallel interfaces 104.Bl -tag -width 12n -offset ind -compact 105.It Xr addcom 4 106Addonics FlexPort 8S serial communication cards 107.It Xr ast 4 108multiplexing serial communications interface 109.It Xr boca 4 110multiplexing serial communications interface 111.It Xr com 4 112serial communications interface 113.It Xr cy 4 114Cyclades Cyclom-{4, 8, 16}Y asynchronous comms board device driver 115.It Xr lpt 4 116parallel port driver 117.El 118.Ss Network interfaces 119.Bl -tag -width 12n -offset ind -compact 120.It Xr ec 4 1213Com EtherLink II (3c503) Ethernet device 122.It Xr ef 4 1233Com Fast EtherLink ISA (3c515) 10/100 Ethernet device 124.It Xr eg 4 1253Com EtherLink Plus Ethernet (3c505) Ethernet device 126.It Xr el 4 1273Com EtherLink (3C501) Ethernet device 128.It Xr ep 4 1293Com EtherLink III and Fast EtherLink III 10/100 Ethernet device 130.It Xr ex 4 131Intel EtherExpress Pro/10 and Pro/10+ Ethernet device 132.It Xr ie 4 133Intel i82586/i82596 Ethernet device 134.It Xr lc 4 135DEC EtherWORKS III 10/100 Ethernet device 136.It Xr le 4 137AMD LANCE Ethernet device 138.It Xr ne 4 139NE2000 and compatible 10/100 Ethernet device 140.It Xr sm 4 141SMC91C9x and SMC91C1xx-based 10/100 Ethernet device 142.It Xr we 4 143Western Digital/SMC WD80x3, SMC Elite Ultra, and SMC EtherEZ Ethernet device 144.El 145.Ss Sound cards 146.Bl -tag -width 12n -offset ind -compact 147.It Xr ess 4 148ESS Technology AudioDrive family audio device 149.It Xr gus 4 150Gravis UltraSound/UltraSound MAX audio device 151.It Xr mpu 4 152Roland/Yamaha MPU401 MIDI UART device 153.It Xr pas 4 154Media Vision Pro AudioSpectrum audio device 155.It Xr sb 4 156SoundBlaster family audio device 157.El 158.Ss Hardware Sensors 159.Bl -tag -width 12n -offset ind -compact 160.It Xr aps 4 161ThinkPad Active Protection System accelerometer 162.It Xr asmc 4 163Apple System Management Controller (SMC) 164.It Xr fins 4 165Fintek F71805F LPC Super I/O 166.It Xr it 4 167ITE IT87xxF and SiS SiS950 temperature, voltage, and fan sensor with 168watchdog timer 169.It Xr lm 4 170National Semiconductor LM78/79/81 temperature, voltage, and fan sensor 171.It Xr nsclpcsio 4 172National Semiconductor PC87366 LPC Super I/O with GPIO 173.It Xr schsio 4 174SMSC SCH311x LPC Super I/O 175.It Xr uguru 4 176ABIT temperature, voltage and fan sensors 177.It Xr viasio 4 178VIA VT1211 LPC Super I/O 179.It Xr wbsio 4 180Winbond LPC Super I/O 181.El 182.Ss Miscellaneous devices 183.Bl -tag -width 12n -offset ind -compact 184.It Xr gscsio 4 185National Semiconductor Geode SC1100 I2C controller 186.It Xr lms 4 187Logitech-style bus mouse driver 188.It Xr mms 4 189Microsoft-style bus mouse driver 190.It Xr npx 4 191Numeric Processing Extension coprocessor and emulator 192.It Xr pcdisplay 4 193PC display adapter driver for wscons 194.It Xr pcic 4 195.Tn ISA 196PCMCIA controllers 197.It Xr pckbc 4 198PC (ISA) keyboard controller driver 199.It Xr pcppi 4 200PC (ISA) control and timer port driver 201.It Xr skgpio 4 202Soekris net6501 GPIO and LEDs driver 203.It Xr vga 4 204VGA graphics driver for wscons 205.El 206.Pp 207Note that some 208.Tn ISA 209devices also have newer 210.Tn ISA 211Plug-and-Play variants. 212These are listed in 213.Xr isapnp 4 . 214.Sh SEE ALSO 215.Xr intro 4 , 216.Xr isapnp 4 217.Sh HISTORY 218The machine-independent 219.Tn ISA 220subsystem appeared in 221.Ox 2.0 . 222
