No.

Its not PNP

What do you mean?  If I were to make a file system image to load into RAM
from ROM (like the install disk) then it woudldn't need disk info, or would
it?

Doesn't NetBSD use the info it gets when it scans the IDE busses?

Its an embedded design I'm making, so unless the wintel stuff is inside the
386...Its not going to be there.  :)

Try later.  www.gci.net and www.gci.com are not very reliable WinNT servers...

The gateway goes up and down so often I can be in the middle of loading a
www page and it will stop.  :\
