Root default login shell changed! Help!

Hi All,
I had changed the root default login shell from /sbin/sh to /usr/local/bin/bash in /etc/passwd file but failed to work and I had accidentally logged out from the server. When I tried to login to the server using root account, it will always prompt me for errors found. Now I can't even use sudo command to take control of the server.
Qn: How can I revert back to the default /sbin/sh login shell for the root account??
I had tried to use the below methods but it can't work(currently the server is running Solaris 8): - "boot cdrom -s" and I was prompted with a login password instead of a hash prompt and I could not even mount the default / root directory to edit the /etc/passwd file!!!

When you
boot -s cdrom (not the other way round)
you should be able to do mount /dev/dsk/c0t0d0s0 (or whatever your root partition is) to /a
then cd /a/etc
and edit the end part in /etc/passwd for the root account shell type. (ie: change it back to /bin/sh)
then just reboot the machine and all should be okay.

The reason it faile dis because /usr/local is not seen at the beginning of boot up, only the root partition with /usr.
It is a very common mistake by beginners.

use: OK boot cdrom after the openwin startup, just open another window to do the work. "boot cdrom -s" will ask you the password.
