I have a number of Compaq DeskPro EN K450 here. Rather decent machines
for FreeBSD desktops, and for sure not uncommon hardware. But
unfortunately the stupid Compaq BIOS doesn't have a knob to turn off
PnP, so I have to rely on PNPBIOS to deal with what the Compaq BIOS had
detected.

With PNPBIOS:

FreeBSD Audio Driver (newpcm)
Installed devices:
pcm0: <ESS 1869 DSP> at io 0x220 irq 5 drq 1:0 bufsz 4096 (1p/1r/0v channels duplex)

Without PNPBIOS: no pcm0.

Latest BIOS revision, of course.

It's not. But without PNPBIOS either won't work on these boxes.
