If you've got Ultra disks, be sure to go into Adaptec's configurator at
boot-time and enable 20M/s transfers.  Also note that the card will
automagically and silently disable 20M/s if there's a slow device (eg., a
CD-ROM drive) on the bus.

Contrary to most of the reports I've seen here, I've had better luck with
enabling PnP on recent Tyan boards, though they're still muxing some IRQ's
for no apparent reason.
