Hi,

I have do some change for the bios. By update microcode to support the CPU, but end up at error on checksum

My system is using i7 720QM. I want to upgrade it to i7 920XM. CPUID: 0106e5

For the i7 920XM is "SLBLW"

For detail:

i7 720QM "SLBLY"
i7 920XM "SLBLW


The BIOS file is the latest from Dell, and also the microcode file

Thank,

I've updated microcode to version 04. It's enough for booting i7-920XM.
Windows updates microcode to version 07.
Check it with new CPU.

So now I will install the i7 920XM to check that it work or not, right?

[DeathBringer]

Right

Nothing happen. The screen doesn't turn on. CPU fan doesn't run. Only hear small sound of HDD spinning

I do with CMOS Battery remove for 5m to reset all setting + Only 1 RAM on Dimm 1 + Without Battery only apdater

It isn't microcode issue. BIOS mod can't help you, because it isn't loaded by a motherboard at all.
