Hardware

Hi,

my Sun Ultra 40 will not boot, it is an AMD Opteron based machine, the cooling fans are spinning, but there is no msg to read on the monitor.

Occasionally I got it to boot, it ran for two weeks, but at next reboot it displays no signal to the video card.

I spotted this in the manual
===

During POST, the BIOS outputs the error code to I/O port 80h. The workstation
motherboard is equipped with a two segment LED display that displays the current
value of port 80h.

but I cannot get the glue in it, maybe because I have opteron AMD and this is targeted to sparc.

Last error msg I read was like this:

what can I do? is the motherboard faulty? How can I get it to boot from CD
and run a system diagnosis?

What mainboard is compatible? should I replace it with a newer mainboard + CPU + RAM?

Will it fit in the Sun Ultra 40 desktop tower?
