[ILUG] Problems Booting UltraSparc

[Dave Burke]

Ar'noon,

Am trying to get Redhat 5.2 onto an ultra sparc at the moment and having
a few wee problems.
I boot it up and hit break and get the ok: prompt. I then try

ok: boot cdrom
Boot device: /sbus/SUNW,fas at e,8800000/sd at 6,0:f File and Args:

Can't open boot device.

I then tried to reset the NVRAM values:
ok: set-defaults
Setting NVRAM parameters to default values.

But still no luck. I can't even boot off the solaris 2.5 or 2.6 cds
either, but if I let it run it'll boot grand off the HDD. I tried plugging
in my external sparc CD-ROM, but I think she got very confused when I
then tried to boot from the CD.

So my questions would be:
1. Is there anything I can do to get it to boot from the CD?
2. Failing that, how do I get it to ignore it's internal cdrom and boot
off the external one?

The machine is a Sun Ultra 1 UPA/SBus and it's running OpenBoot 3.1, if
thats any use. I tried to do a "test-all" but that just hangs at the
"Transceiver check ---" prompt.

Any help, links, appreciated,
Dave
