You cannot boot without a CPU. There may be also a problem with your disks. Consider to call HP and let them check your hardware first.

in case of fixing the CPU & HW issues, what is the ability of restoring or fix our HP-UX?

[Torsten.]

It really depends on what is broken - if the disk has failed, you have a problem without any backup ...

[Mohamed Galal]

I think we don't have problem with the Hard-Disk. we have problem with CPU 0. how can i disable it till change it? i tried to do it:
CO >> CPUconfig 0 OFF. but it could not boot even from DVD.

how can I re-install the drivers in this case? how can i run "insf -e".?

[Torsten.]

You always need the CPU 0 (monarch) to boot.

The MISSING DRIVERS??? message indicates a problem, but most of the times NOT a driver problem!

;-)

The system cannot access (parts of) the disk, so it "thinks" this could be a driver problem, what in fact is never the problem.
