ISA(4) Device Drivers Manual ISA(4) NAME isa - introduction to machine-independent ISA bus support and drivers SYNOPSIS Attachments are machine-dependent and depend on the bus topology and ISA bus interface of your system. See intro(4) for your system for details. DESCRIPTION NetBSD includes a machine-independent ISA bus subsystem and several machine-independent ISA device drivers. Your system may support additional ISA devices. Drivers for ISA devices not listed here are machine-dependent. Consult your system's intro(4) for additional information. SUPPORTED DEVICES NetBSD includes machine-independent ISA drivers, sorted by device type and driver name: SCSI interfaces adv Advansys SCSI interfaces. aha Adaptec AHA-154x family (154xA, 154xB, 154xC, and 154xCF) and the BusLogic BT54x SCSI interfaces. ahc Adaptec 29xx, 39xx, and other AIC-7xxx-based SCSI interfaces. aic Adaptec AIC-6260 and Adaptec AIC-6360 based SCSI interfaces, including the Adaptec 152x, SoundBlaster SCSI interfaces, and a variety of compatibles. bha BusLogic BT-445 SCSI interfaces. dpt DPT SmartCache/SmartRAID III and IV SCSI interfaces. esp NCR 53C9x, Emulex ESP406, and Qlogic FAS408 SCSI interfaces. nca NCR-5380/NCR-53C400 sea Seagate/Future Domain SCSI cards.

Note that some ISA devices also have newer ISA Plug-and-Play variants. These are listed in isapnp(4). Some i386 platforms use pnpbios(4) to attach ISA devices. DIAGNOSTICS Stray interrupt on IRQ 7 It means the interrupt controller reported an unmasked interrupt on IRQ 7, but no driver attached to that IRQ `claimed' it. There are two reasons this can happen: ⊕ In anything other than i386, it would almost always mean that there is a driver attached to the IRQ, but it is the wrong driver. ⊕ On i386, there is the more obscure issue of `default IRQ7's. That is, when a device asserts an IRQ, but the IRQ is deasserted after the PIC latches the interrupt and before the CPU acknowledges it, the PIC just flat out lies about which IRQ it was. It is usually due to a suboptimally coded driver.
