Hm.  I don't recall trying that.  (But then, it was quite a while back
that this happened.)  I should bring the machine down and try it.

Yes.  It's NetBSD (albeit a somewhat old version), and once it's loaded
the kernel and identified its boot device, I don't think it uses the
BIOS for anything disk-related any longer.

I actually think the most annoying part in this case will be moving all
the data off that disk so I can play with it in data-destroying ways!

I can get into setup if the drive is not connected.  I don't recall
ever making it to setup with the drive connected - except when the BIOS
is configured to "none" for that slot.

This too I'll have to investigate when I bring the machine down to play
with it.  Probably not until I get another disk to hold the data.
