Add microcode CPUID 0F29h in Gigabyte GA-8IRXP

[telescopius]

Hello,

i have an GA-8IRXP Socket 478 Mainboard.

I have successfully used Pentium 4 CPUs with CPUID F27 and Core Stepping C1 - no problem.

But Board refuses to boot with Pentium 4 with CPUID F29 and Core Stepping D1.

Between these CPUs anything else is the same:

Processor Core: Nortwood
Package: 478
L2 Cache: 512 kB
Bus Speed: 533 Mhz

only the Core Stepping and therefore CPUID is different.


Latest original BIOS is: http://download.gigabyte.us/FileList/BIO...rxp_f9.exe


Can someone modify this BIOS to support microcode CPUID F29 ?

many thanks in advance
