[parisc-linux] Booting palinux-0.6.1-32STI ISO on HP 705 problem (failed to load kernel)

[Derek Wilson]

Hello


First of all, thank you to everyone working on parisc-linux.

I have been asked to install linux on a few HP 700 machines. I was
recommended to try a 705 machine first as it had a CDROM and reportedly
worked well. It has 32 MB of RAM, hard disk size unknown.  It boots into
the CDE login screen without any problems, as far as I can tell. We
don't know the root password, or usernames and their passwords.

I downloaded the palinux-0.6.1-32STI.iso.gz file from
ftp://puffin.external.hp.com/pub/parisc/cd-images
and burned it to CD. I then tryed booting this CD from the CDROM on the
705 machine. It seemed to access the CDROM for a few seconds then die.
This is the output sent to the monitor

>From looking at another boot log
http://lists.parisc-linux.org/pipermail/parisc-linux/2001-May/012555.html

it seems that the installation dies before or when it tries to `branch
to kernel entry point 0x00100000'

Why might this be?

If I try booting from a serial console, over NFS or using rbootd will I
run into the same problem?

I see that 710 machines appear to have problems with "interrupt routing
from the scsi and lan chips to the cpu". Could 705's have the same
problems (705's and 710's use the same scsi driver according to the
hardware database, so presumably they use at least very similar scsi
hardware), and is this the cause of my problem?

Any and all help will be gratefully received, on or off list.


Thanks in advance, Derek.
