Posted: 18 Nov 03

There
are are a few options to get into Single User Mode on a Sun Solaris
system when you do not have a Sun Keyboard. Below are a few
suggestions on how to accomplish this task.

Step 1: Open a terminal session to the Sun Solaris system using a PC comm port and Hyperterminal (9660,8,None,1).

Step 2: Login as root.

Step
3: Type 'reboot [option] -- -s'. This will reboot the Solaris system
and execute the 'boot -s' option.

Alternatively, you could also type

'init 0'.

This will bring you to an 'ok' prompt. At the 'ok' prompt,
type

'boot -s'.

Either command should bring you into single user
mode. The second option does not initiate a system reboot.
