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.

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.
- 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.
