Hi,

You should interupt the booting when it ask you to press any key within 10 secs.

It will take you to menu, where you need to give this command.

Menu> bo pri

It will ask, do you want to interact with IPL Y/N ?

Give "Y" . It will take you to ISL prompt. In ISL give this command.

ISL>hpux -is

This will boot the system into single user mode.

Only root and stand will be mounted in single user mode. You can manually mount other filesystems if you need.

This steps are for PA-RISC systems. For itanium steps are different to boot into single user mode.
