Sun No Bios

My Sun Ultra 24 will not power up.

I took out both video cards and put in a new power supply.

Power on Yellow LED on Mother board comes on

a LED displays FF on the motherboard

and a Green LED comes on also for a few seconds?

Then cycles off and trys to restart again?

What does the "FF" code mean on the Motherboard LED Display?

Anyone have a List of Motherboard codes from SUN Intel Processor Workstation. Its a Quad Core Intel 6600 fast and worth fixing to me?
