Hello,
My Mac Pro won't boot anymore, I am getting chime, and upon checking the diagnostic LED's, the trickle power and GPU LED's are ON.
none of the CPU LED's indicating issues are ON.
But also the EFI DONE LED IS OFF - so I tried restoring firmware using the CD I burned from Apple support site, with no luck, I tried using two different CD drives to be sure.
That leads me to thinking that the EEPROM holding the EFI firmware may be dead, and I'm willing to reflash and in the worst case replace the chip.
Thing is, I can't find it on the motherboard. I even found another post (http://www.amibay.com/archive/index.php/t-52171.html) but it seems that's a different version of motherboard, so the location pictured does not help me.
Please help if you know the location of the chip.
Thanks
