ISAPNP(4) FreeBSD Kernel Interfaces Manual ISAPNP(4) NAME isapnp - introduction to ISA Plug-and-Play support SYNOPSIS isapnp0 at isa? DESCRIPTION An isapnp bus can be configured for each supported ISA bus. OpenBSD provides machine-independent bus support and drivers for ISA Plug-and-Play (isapnp) autoconfiguration of PnP-compatible devices on an ISA bus. SUPPORTED DEVICES OpenBSD includes machine-independent ISAPNP drivers, sorted by function and driver name: Disk controllers aic(4) Adaptec AIC-6260 and AIC-6360 SCSI interface wdc(4) WD100x compatible hard disk controller driver Serial and parallel interfaces com(4) serial communications interface Network interfaces an(4) Aironet 4500/4800 IEEE 802.11FH/b wireless interfaces ef(4) 3Com Fast EtherLink ISA (3c515) 10/100 Ethernet device ep(4) 3Com EtherLink III and Fast EtherLink III 10/100 Ethernet device le(4) AMD LANCE Ethernet device ne(4) NE2000 and compatible 10/100 Ethernet device we(4) Western Digital/SMC WD80x3, SMC Elite Ultra, and SMC EtherEZ Ethernet device Sound ess(4) ESS Technology AudioDrive family audio device gus(4) Gravis UltraSound/UltraSound MAX audio device mpu(4) Roland/Yamaha MPU401 MIDI UART device sb(4) SoundBlaster family audio device Miscellaneous devices joy(4) games adapter pcic(4) ISA PCMCIA controllers SEE ALSO intro(4), isa(4) HISTORY The isapnp driver appeared in NetBSD 1.3. CAVEATS From time to time an isapnp device will be found which the kernel does not recognize. The kernel matches isapnp devices to device drivers based on identifiers which each device provides. For example, this device: joy0 at isapnp0 "Creative SB16 PnP, CTL7001, PNPB02F, Game" port 0x200/8 This joystick calls itself by the two names "CTL7001" and "PNPB02F". The latter is a standard name (which the kernel automatically recognizes), but "CTL7001" is a vendor-specific name which needs to be added to a table. Unfortunately, some devices advertise only their vendor-specific name; for instance: "PnP Sound Chip, @P@1001, , " at isapnp0 port 0x200/8 not configured Testing will show that this device is actually a joystick. To resolve the issue, the actual name "@P@1001" has to be entered into the database found in /sys/dev/isa/pnpdevs and a new kernel must be built. Then the device will probe like this: joy0 at isapnp0 "PnP Sound Chip, @P@1001, , " port 0x200/8 FreeBSD 14.1-RELEASE-p8 April 27, 2023 FreeBSD 14.1-RELEASE-p8
