Boot to Single User Mode

Here are a few ways to boot a workstation to single user mode. This mode is primarily used to perform maintenance or troubleshooting activities. Occasionally, you may encounter an emergency and will have to use a CDROM to boot to single user mode.

From Open Boot Prom (OBP)
You will be prompt for a password if security-mode is set to command
ok boot -s
ok boot cdrom -s

From the init 3 level
This will automatically execute a boot -s at the OBP level
#reboot -- -s
