Hi,

I bought a used Sun Ultra1 with 143MHz CPU. The battery chip (TOD) is
dead. The OPB is version 3.1. I put 256M RAM and tried to install
Solaris 2.6. During the installation, the Sun Ultra1 reboots itself
ramdomly. I checked the CPU fan and it's working. Then, I tried to
install Solaris 7, it still reboots itself during the installation. I
do not know what is wrong with the machine. Is it the hardware problem
or anythings else? Your help is much appreciated.


Charlie

I would strongly suspect the RAM you put into the thing as being flakey.

The dead NVRAM isn't going to do much for you for the install,
although you'll have lots of problems trying to talk on the Ethernet
port once you get that far from that.

If you have known good RAM in there, and the problem still occurs, the
next thing to check is the fan ontop of the CPU (IIRC, it had one in
this model) to make sure it not gunked up and letting the CPU
overheat. After that, I'd chalk it up to a bad motherboard, not worth
getting fixed.

The NVRAM chip can be replaced or a new battery kludged onto it.

As Doug mentioned you probably have some flaky memory. It can be checked
during POST by holding Stop-D on the keyboard during power up. Or

ok> setenv diag-switch? true

from a serial terminal. Then power cycle the machine.

try the OBP POST test

ok setenv diag-switch? true
ok setenv diag-level max
then ok reset-all
or power off and on
now POST diag will run, takes minutes be patient.

to set things back
ok setenv diag-switch? false
