isa -- introduction to machine-independent ISA bus support and drivers
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.
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.

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.
