Hi all,

I have just acquired my first "real" server, an old 2U Quad socket supermicro with 4x Xeon E7320 and 48GB of RAM installed.

I plan to use Xen (personnal preference, might try ESXi too if possible) to consolidate 5 old IBM x306m 1U single pentium 4/512M servers with low utilization.

The remaining capacity is mine to play around with :D.

The motherboard is a supermicro X7QCE quad-socket-604 with intel 7300 chipset. Supermicro's website mentions the board supports "6-Core Intel® Xeon®
Processor 7400 sequence" CPUs.

I have bought separately 4x Xeon E7458 CPUs, which are like 7450 but with 16M L3 (a la 7460). I know these where "oem only" CPUs sold in HP servers. But since they were very cheap, I took a chance.

My question is thus :

Is BIOS support for a CPU implemented on a model basis or a family basis, especially nowadays that multipliers and such are all configured on the chip.

More succintly, is there a chance in hell this might work?
