Yep, that method works for now.
I was hoping its easy enough to crack this myself (with some online
tips & references) but John Baldwin convinced me otherwise :-)
So here's the entire configuration attached..
SUMMARY:
The boot disk (ad0 in attachment) is not the problem.
There are two other IBM SCSI disks attached to two Adaptec cards.
Its these other two SCSI disks-da0,da1 which are empty and
whose disklabels I played with. These cause a BTX error if
they are plugged in during a boot.
TIA,
-Sandeep
