So, what about those of us (I assume I am not the only one) with a
situation such as: DOS on C: (wd0) and D: (sd0), WinNT on E: (sd0),
and *BSD (sd0) (in this case, FreeBSD, but that may or may not change
as new releases come out, until I settle on one (it used to be
386bsd))? I have the beta of OS-BS and can boot off of the scsi disk,
but I always have to type the "sd0(1,a)/386bsd" (or whatever it is, I
don't remember -- haven't booted to bsd in a few days, I've been
working on the SGI and Sun).
Any solutions to this? I will be adding another IDE drive and
additional SCSI drives as money allows. (I'll probably end up running
both *BSD's for a while.)
Thanks,
-bkc
PS - I'm not entirely clear on how I put this boot code in place, once
it is working.
