Hello all! I happened upon this board while searching for help with a bit of a situation I have on my hands.
I recently obtained a working Dell Precision 690. It came with an LGA771 Intel Xeon 5050. I did some research and was convinced that the system would be able to support two x5450 processors, since the chipset (Intel 5000x) supports it, similar voltage range, FSB, and so on.
However, it seems that I didn't do ENOUGH research. I purchased the processors, installed them, and the system failed to get past POST. I would run a couple of tests, and halt displaying a couple of diagnostic lights, with no video display. Looking around, I found that some people have had similar problems when trying to use a CPU that is not supported by the system. Turns out that early revisions of the 690 bios lacks quad core support (which mine falls into this category). Further, in the revisions that do support quads, the 54xx Xeons have been left out.
Would it be possible to add support for this processor line? Assistance would be greatly appreciated; here's some information to help out...
Original CPU:
Intel Xeon 5050
spec number: SL96C
CPUID: 0f64h (I believe)
The CPUs I purchased:
Intel Xeon x5450
spec: SLASB
CPUID: 10676h
Precision 690 BIOS:

My current one is the A00 revision.
As for the donor BIOS recommendation, I located a Dell BIOS for a system that uses the Intel 5000x and has support for the x5450:
