Intel D815EFV - Remove Tualatin Pentium Block

[maewiotr]

Here I have an old, circa 2003 motherboard from Intel.

It will boot only with Celeron Tualatins, but if you try a Pentium III-S, it will POST, but it gives a message that the CPU is not supported and won't let you proceed.

The Intel BIOS is segmented into a bunch of files:

BIOS.REC
P21-0039.BI1
P21-0039.BI2
P21-0039.BI3
P21-0039.BI4
P21-0039.BI5
P21-0039.BIO
P21-0039.SIG

It can be downloaded here:

I'd appreciate it if someone could take a look.

Thanks
