Dear Rich,
This sort of happened to me, once. I accidentally installed onto
wd2, and then after booting part way, it said 'changing root device to wd1a'
which is sort of the opposite of what is happening to you.
Part of the cure was to halt the boot during a pause that it gives you,
and get a list of commands (by typing 'help'), I think. There
was a command in there that went something like
'set root device to wd2s1a'
Then it booted from my correct drive.
Unfortunately, after replugging my drive to controller 1, so
it was now wd1, my etc/fstab was pointing to the wrong drive. The
cure to that was to mount /dev/wd1a /mnt which is a loophole that
allows you to mount the same partition writable which was readonly.
I hope noone fixes this loophole. I was never able to get vi
working in this mode so I could edit /etc/fstab, so I copied an
fstab file from a floppy.
Unfortunatley, /dev/wd1s1a thru f were not in /dev, and the
/stand/sysinstall refused to create them. I think I went to
/mnt/dev and did a 'sh MAKEDEV wd1s1a' , which created a thru f.
Or maybe I had to replug to controller 2 (back to wd2a) and then
do this.
I apologize for imperfections in my memory of the above. I have
not gone so far as to reboot my system to watch for the exact
syntax of the boot option commands, for instance. Hope
this helps some, anyway.
