Hello!
I need to mod BIOS of Dell Vostro A860 and add newer CPU microcode to that.
I have tested and this laptop work with Penryn CPU like T4300 but every boot is complaining about failed cpu microcode update.
I checked and looks like only below microcodes are in A860A02.EXE (link) BIOS update:

CPUID=6F4 Rev=28 2006/04/17 CRC=30DD8681 Off=5D48F Size=1000 Plat=0,2,4,5,6,7
CPUID=6F5 Rev=38 2006/07/25 CRC=6333B559 Off=5E48F Size=1000 Plat=7
CPUID=6F9 Rev=83 2006/09/28 CRC=85B7E1DF Off=5F48F Size=1000 Plat=7

CPUID=10676 Rev=60C 2008/01/19 CRC=FBAC0EED Off=6748F Size=1000 Plat=7

CPU microcode from other Dell laptop like 1545A13.EXE (link) have what i need:

CPUID=6FD Rev=A3 2007/08/13 CRC=89C0D01F Off=5E173 Size=1000 Plat=7
CPUID=10671 Rev=106 2007/03/29 CRC=80731B2D Off=5F173 Size=1000 Plat=7
CPUID=10674 Rev=405 2007/07/20 CRC=735D9FE0 Off=60173 Size=1000 Plat=7
CPUID=10676 Rev=60C 2008/01/19 CRC=FBAC0EED Off=61173 Size=1000 Plat=7
CPUID=1067A Rev=A07 2008/04/09 CRC=83067ECB Off=62173 Size=2000 Plat=5,7

How i can swap this microcode between this models? Please help me.

Phoenixtool will help me make changes to dump files and compile it to new working exe flashable?
How to find module for replace and how to fix eventually mismatch in file size?
Maybe there is some bin files with updated intel socket P microcode for update some way with CBROM?


I have found model with same motherboard and newer bios, i will try use it, maybe will help somebody make this mod:
1015_A06.EXE


When i try to extract CPU microcode from newer model it usage endless CPU with blinking cursor:
CBROM399 1015_A06 /nc_cpucode ncpucode.bin


I have extracted microcode with MC Extractor but still don't know how to replace microcode:
cbrom399 a860a02 /nc_cpucode cpu1067A_platA0_ver00000A07_2008-04-09_PRD_83067ECB.bin
Result: still blinking cursor and even when it will work, i don't know how to flash this bios (I am operating on 2MB file extracted with 7zip from dell exe).
