How do I reset the (Old Sco Unix) root password if I forget it? (part 3)

(For Linux, see Lost Linux Root Password)

This procedure will work for any variant of SCO Xenix or Unix. As above, boot from your emergency boot diskettes and

mount /dev/hd0root /mnt

to gain access to your hard drive's root filesystem. Now, run

/mnt/bin/chroot /mnt "/mnt/bin/passwd root"

(check the chroot man page for more info on how it works). As before, shut down and reboot. It has been reported that on 3.2v4.2 (and possibly others), this must be done in two steps:

/mnt/bin/chroot /mnt "/bin/su root"

If it doesn't work with the quotes, try it without.
