Ultra 5 Boot Hang Update.

[Zaphod Beeblebrox]

OK.  I took everyone's suggestions to heart.  I downloaded the 9.3 disk1
and copied it's kernel onto tftp.  I also disconnected the CDROM and the
hard drive I had the box.  I also disconnected the floppy.  At this point I
checked the operation of the fans.  All good.  Nothing but the motherboard
and riser in the machine now.

After all this, it stops the boot in much the same place.  You can see that

As before STOP-A doesn't do anything anymore.  I've always thought STOP-A
was a poor key choice... I've accidentally typed it on several workstations
that I've owned in the SPARC family.

So... ideas?  Is this machine just hosed?
