ISA(4)                  NetBSD Kernel Interfaces Manual                 ISA(4)

     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.

     NetBSD includes machine-independent ISA drivers, sorted by device type
     and driver name:

     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'

     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.
