Hi,

to install a C3000 workstation with HP-UX 10.20 you need a special Core-OS CD:

Core-Os 10.20 ACE4 from 99/06

This Core-OS CD contains the necessary ACE patchbundle. Without this patches you are not able to install this system.

Regards,
Armin

What steps are you following?
You need to boot the machine, interrupt the boot process, search for the boot path of the CD drive, and enter that boot path.

Need more info.

Hi all,
Thanks for the reponse.
This is the procedure I followed:
- Interrupt boot
- Search for boot device
- Select CD-ROM
This is the error I get:

Thanks again.Bye

status ???4 is usually a scsi error.
check all you scsi cables and make sure your terminated. Also look for bent pins.
Then try again.

Looks like cpu0 has problems - place a hardware support call.

ENTRY_INIT -4 Causes:
- the disk is experiencing hardware faults and needs replacing.
- the path to the disk is experiencing problems. e.g.. Termination,
cabling, SCSI adapter, SCSI adapter seating.

Guess it could also be the CD it's self.
make sure the CD is in good shape

Probably I am not familiar. I never heard of any server called AC-3000. Can you confirm it?.

Thanks,

Hi,

Could it be there is some hardware in the machine which was not supported at the time of the release of the ACE 99 cd ?

That could explain the reason why the install is failing !

I am not sure if these error's are related to such an issue.

Finally HP-ux 10.20 could be installed by deleting some config files (vmunix) for the HP-ux 11 installed. Unfortunatelly I was out when the technician did the job and I has no detils about it.

Thanks all for your help and I hope that this info cuold help someone.
