Default reboots on ultra1

Hi,

I recently got an Ultra1 station, but it seems there is something sucks
with this computer...

If I get it unplugged (the power cord) for days and then boot it, il will
work well. But if i let the power cord plugged all the time, when power-on
(with the keyboard power button, or the PSU power switch) I get the
OpenBoot screen, it starts booting, and... it reboots !
The internal speaker emits some blops-blops, sometimes I get OpenBoot again
and rebbot agains, sometimes the screen remains black and I hear lot of
"speaker blops"...

When I got this station, it didn't boot because CPU fans and PSU fans where
damaged. I changed them and it worked again, but now I fear something fried
somewhere...

any idea ?

Default Re: reboots on ultra1

I have an issue with my Ultra1 that is the reverse. If I leave mine off
for a long time (a few months), I have the same issue (beeps from the
speaker, box won't boot), but if I fire it up every day I have no
issues. .

I went back to the ok prompt and did a probe-scsi-all which showed the
hard drive was offline.
What I did was boot cdrom -s from the the ok prompt and run format. I
guess the probing was enough to bring the disk back online because I
was able to see the disk and mount the partitions.

If doing the boot cdrom -s and format dowsn't work for you my guess
would be a hard drive replacement is in order.
