Ultra 5 refusing to boot The charity recycling project where I volunteer
has been donated a Sun Ultra5. It's in near
perfect condition, but doesn't complete the boot
process.
It looks to be a 400MHz machine, with four 64MB
DIMMs and an LSI Logic SCSI card. The hard disk
has been removed, but everything else seems to be
present. I'm testing it with a Type 6 keyboard.
The immediate symptom is that there's no display
on the monitor. I hooked up a dumb terminal to
the serial port, and enabled the full POST.
The POST checks run fine, and report a pass. The
system then tries to boot normally, but hangs...

The cursor sits at the end of the "Size" line, and
the system goes no further.
Can anyone suggest what might be wrong, or further
testing I can do to help diagnose the problem?
Thanks for your help.
