i recently received a sun ultra 10. i have powered it up with a sun monitor plugged into the on board video port
and the green light on the sun monitor blinks the machine seems to whirr and run with nothing onscreen.
i have tried the stop+A key combination to go into obd to no avail.

turn off the monitor and unplug the power cable, and reconnect the monitor, then
try again.

If it doesn't work,  try to use a different monitor to see if there is a problem with the
monitor itself.

The next thing you can try is to reset the NVRAM, by try in <Stop> N key

hold down <Stop> N keys while you turn the power on for a few seconds, see if it can help.

It could be memory, or CPU or mainborad or graphic card or NVRAM chip problem.

try to re-sit the memory to see if it can help.

if you have another Ultra 10 or Ultra 5, you can try to move the HD to the Ultra 10/5
boot it up and check /var/adm/messages file to see if any error messages.

You can also swap the NVRAM chip to see if you need a replacement.
(ps: the NVRAM in Ultra 5 also works with Ultra 10)

Please read the Ultra 5/10 service manual:
http://docs.sun.com/app/docs/prod/1938#hic

Before open the box.

the memory!  i reseated the memory and held my breath...on powerup i had video.

thank you!

i had no idea...the manual states that there could be a ´hardware problem´ which leads to a conundrum of which where and what.

thanks again for directing me in a good direction
