The machine seems usable now.
It's flaky in a way I don't understand.
Both the PSU's have green lights on them but when
it comes up it autoreboots at test 60.. continuously for
a reason I have to determine someday.
Until then it seems to be OK if I halt the boot, wait about
four minutes and then restart. It goes all the way to boot
3.. and then takes the 'b dia0', and 'sho dssi'. Whatever.
Anyone recognizing the symptoms can add a message.
Till then.
