  I'm certainly no expert, but isn't wd0d the partition that defines the
entire disk?  As in, it ignores whatever is in the label and just grabs
the WHOLE DISK?  As in, starts with your DOS stuff and snarfs from there...

  I have never heard of anyone having a working system where they used
the wd0d partition for ANYTHING except the entire disk drive.

  BTW, wd0c is normally the partition definition for the entire 386bsd
partition.  It should start in the same place your wd0a partition
does.  I would change all references from wd0d to wd0e and wd0e to wd0f,
or something like that.

  Try the wd0d -> wd0(Something greater than d) thing first.  See if
that fixes it.  Of course, you might end up reinstalling if OS/2
eats your bsd partition again (Nazi software strikes again!).  Of 
course, I guess it would only be getting even for your /var partition 
eating the DOS partition :-).
