ThinkPad X220 - UEFI module in vbios - not true

[techuser]

GPU-Z 2.30 and probably many older versions show that the Intel HD3000 graphics card on ThinkPad X220 (bios 1.46 8DET76WW) has a UEFI module - this is not true.

I have a question: How does the program detect the UEFI module in vbios? If the program found the UEFI module in vbios, why can't SAVE it to a file?

The GPU-Z 0.8.4 version works well and the UEFI box is not checked:


BIOS Version DB20895 PC 14.34 - as shown by GPU-Z this is vbios legacy available in memory at the address C0000.

Uncompressed Intel UEFI GOP driver is portable executable, starts with the MZ string and is described as Intel(R) GOP Driver - this is screenshots what Intel GOP looks like from another computer:

Why do you need to backup or restore such an Intel GPU BIOS at all?
Are you trying to over or underclock the GPU somehow?

How does the program detect the UEFI module in vbios?

Sandy Bridge and newer IGPs are marked as UEFI supported, older GPU-Z simply always said "not supported" for all Intel

No, I don't want to make a backup, restore or overclock.

I only mean this UEFI option in the program.

That's not good

So this means that the program only detects the platform e.g. Sandy Bridge and does not really check if vbios contains GOP module?

There were Sandy Bridge computers that had UEFI bios with GOP and without GOP vbios e.g.:

• ASUS P8H61-M LE R2 UEFI bios 1408 - GOP is present
• ThinkPad X220 UEFI bios 1.46 - there is no GOP

GPU-Z does not recognize the video bios, so how can it know if vbios has the UEFI module or not?
Below is a screenshot bios setting and GPU-Z on Win10 running in pure UEFI (GOP) without CSM on ASUS:
