A natural suspicion; my only reason for believing otherwise is that
for several devices whose IRQs can be manually configured in the BIOS
(IR port, serial port, parallel port), the BIOS's help screen and the
system manual say that the BIOS will describe these devices as
``Configured by PNP OS'' if those devices are configured by Windoze
9[58]. Otherwise, that option does not appear in the BIOS setup.
That's my only reason for suspecting that there should be some PNP
devices detected.

The BIOS mentions the sound card not even once.

I had hoped that SoundBlaster compatibility implied that the chip
would be usable by drivers that were only aware of ISA cards, but
maybe I'm just confused.

Umm, is that bad? I'd tried OSS (in addition to both sound drivers
that come with FreeBSD) mostly because it was yet another thing thing
that might work.
