[1] boot from cdrom

ok boot cdrom -s

[2] mount root partition read/write on /a
# mount /dev/dsk/c0t0d0s0 /a

[3] set TERM
# TERM=vt100

[4] vi /a/etc/shadow

Here, delete the root passwd hash (not the whole line. just the hash)
And, save the file.

[5] Unmount root partition
# umount /a

[6] reboot from root disk to single-user mode. safety first :slight_smile:
# reboot -- -s

[7] Hit <enter> when prompted for root password

[8] Once you get a shell, set root password
# passwd

[9] Reboot to go back to your default run-level/milestone
