Need Help on Sun 100 / 2.2 Unix

[Matt Landau]

I've just finished upgrading 2 ancient Sun Workstations (a 100U and a 150U,
one a fileserver for the other) from 1.4 to 2.2 Sun Unix.  The server seems
to run correctly, but the client fails to boot, claiming that it can't mount
its root filesystem and giving the error message "rootmount: can't mount
root  mount error = 5".  However, I can mount the client's root on the
server by using "mount /dev/ndl0 /mnt" and verify that it looks fine.

Any Sun 1xx gurus out there have an idea what's going on?
