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 ahc 4 86Adaptec VL/EISA/PCI SCSI interface 87.It Xr aic 4 88Adaptec AIC-6260 and AIC-6360 SCSI interface 89.It Xr uha 4 90Ultrastor SCSI interface 91.It Xr wds 4 92WD7000 compatible ISA SCSI interface 93.El 94.Ss Disk and tape controllers 95.Bl -tag -width 12n -offset ind -compact 96.It Xr fdc 4 97NEC765 compatible floppy disk driver 98.It Xr wdc 4 99Standard Western Digital type hard drive controllers: MFM, RLL, ESDI, 100and IDE/ATAPI. 101See also the 102.Xr pciide 4 103device driver which is used instead on machines with PCI IDE controllers. 104.El 105.Ss Serial and parallel interfaces 106.Bl -tag -width 12n -offset ind -compact 107.It Xr addcom 4 108Addonics FlexPort 8S serial communication cards 109.It Xr ast 4 110multiplexing serial communications interface 111.It Xr boca 4 112multiplexing serial communications interface 113.It Xr com 4 114serial communications interface 115.It Xr cy 4 116Cyclades Cyclom-{4, 8, 16}Y asynchronous comms board device driver 117.It Xr hsq 4 118multiplexing serial communications interface 119.It Xr lpt 4 120parallel port driver 121.El 122.Ss Network interfaces 123.Bl -tag -width 12n -offset ind -compact 124.It Xr ec 4 1253Com EtherLink II (3c503) Ethernet device 126.It Xr ef 4 1273Com Fast EtherLink ISA (3c515) 10/100 Ethernet device 128.It Xr eg 4 1293Com EtherLink Plus Ethernet (3c505) Ethernet device 130.It Xr el 4 1313Com EtherLink (3C501) Ethernet device 132.It Xr ep 4 1333Com EtherLink III and Fast EtherLink III 10/100 Ethernet device 134.It Xr ex 4 135Intel EtherExpress Pro/10 and Pro/10+ Ethernet device 136.It Xr ie 4 137Intel i82586/i82596 Ethernet device 138.It Xr lc 4 139DEC EtherWORKS III 10/100 Ethernet device 140.It Xr le 4 141AMD LANCE Ethernet device 142.It Xr ne 4 143NE2000 and compatible 10/100 Ethernet device 144.It Xr sm 4 145SMC91C9x and SMC91C1xx-based 10/100 Ethernet device 146.It Xr we 4 147Western Digital/SMC WD80x3, SMC Elite Ultra, and SMC EtherEZ Ethernet device 148.El 149.Ss Sound cards 150.Bl -tag -width 12n -offset ind -compact 151.It Xr ess 4 152ESS Technology AudioDrive family audio device 153.It Xr gus 4 154Gravis UltraSound/UltraSound MAX audio device 155.It Xr mpu 4 156Roland/Yamaha MPU401 MIDI UART device 157.It Xr pas 4 158Media Vision Pro AudioSpectrum audio device 159.It Xr sb 4 160SoundBlaster family audio device 161.El 162.Ss Hardware Sensors 163.Bl -tag -width 12n -offset ind -compact 164.It Xr aps 4 165ThinkPad Active Protection System accelerometer 166.It Xr asmc 4 167Apple System Management Controller (SMC) 168.It Xr fins 4 169Fintek F71805F LPC Super I/O 170.It Xr it 4 171ITE IT87xxF and SiS SiS950 temperature, voltage, and fan sensor with 172watchdog timer 173.It Xr lm 4 174National Semiconductor LM78/79/81 temperature, voltage, and fan sensor 175.It Xr nsclpcsio 4 176National Semiconductor PC87366 LPC Super I/O with GPIO 177.It Xr schsio 4 178SMSC SCH311x LPC Super I/O 179.It Xr uguru 4 180ABIT temperature, voltage and fan sensors 181.It Xr viasio 4 182VIA VT1211 LPC Super I/O 183.It Xr wbsio 4 184Winbond LPC Super I/O 185.El 186.Ss Miscellaneous devices 187.Bl -tag -width 12n -offset ind -compact 188.It Xr gscsio 4 189National Semiconductor Geode SC1100 I2C controller 190.It Xr isagpio 4 191ISA I/O mapped as GPIO 192.It Xr joy 4 193games adapter 194.It Xr lms 4 195Logitech-style bus mouse driver 196.It Xr mms 4 197Microsoft-style bus mouse driver 198.It Xr npx 4 199Numeric Processing Extension coprocessor and emulator 200.It Xr pcdisplay 4 201PC display adapter driver for wscons 202.It Xr pcic 4 203ISA PCMCIA controllers 204.It Xr pckbc 4 205PC (ISA) keyboard controller driver 206.It Xr pcppi 4 207PC (ISA) control and timer port driver 208.It Xr skgpio 4 209Soekris net6501 GPIO and LEDs driver 210.It Xr tcic 4 211Databook PCMCIA controller driver 212.It Xr vga 4 213VGA graphics driver for wscons 214.It Xr ykbec 4 215Ene Technology KB3310B embedded controller chip 216.El 217.Pp 218Note that some ISA devices also have newer ISA Plug-and-Play variants. 219These are listed in 220.Xr isapnp 4 . 221.Sh SEE ALSO 222.Xr intro 4 , 223.Xr isapnp 4 224.Sh HISTORY 225The machine-independent ISA subsystem appeared in 226.Ox 2.0 . 227
