NetBSD doesn't yet support Plug-and-Pr^Hlay.  If your momboard lacks a
PnP BIOS (which would be odd, because a P166 board should be
relatively recent), then the card will never show up on the ISA bus
unless it's been configured via some kind of PnP driver.

Some BIOSes have an option to disable Plug-and-Pr^Hlay configuration;
if yours has such an option, make sure that BIOS PnP configuration is

Try warm-booting into NetBSD from DOS, and see if that helps.  PnP
configuration should survive across warm boots.

You may also want to avoid using IRQ 15, because it's the secondary
IDE IRQ.  If you only have one IDE interface in your system,
