MXM: VBIOS / build-in VBIOS

[[email protected]]

Hi Everybody,

 

I am the owner of a HP elitbook 8770W, an old but still very decent notebook.

I've upgraded the GPU several times , first with a GTX 970M and a while later with a GTX 1070 mobile.

I've bought those cards from pretty reliable sources (a seller on Ali I know pretty well) and I knew beforehand that the cards were compatible with my 8770w.

Unfortunately, my 1070 broke down due to heating issues.

 

Now I can get my hands on a Quadro P5200. The original ones don't have a EEPROM chip soldered on the board, and rely on the notebook VBIOS.

However, the one I want has a BIOS chip soldered on the board with a HP max-q bios, which would be perfect for me.

Well, if it's compatible of course.

The seller cannot give me a statisfactory answer to that and I'm not sure they are willing to refund me if this is not the case.

 

Now on to my concrete questions:

• Does the build-in notebook VBIOS matter if there is a chip with a bios on the mxm card itself?
• If it does matter, since my notebook does recognize other pascal cards like the 1070 and 1080, is it wild to assume that a P5200 will also be recognized? They all seem to have a 86.04.x.x.x BIOS.
• Is there any way to check the notebook VBIOS compatibility against the one on the card?

 

Thank you in advance!

Hi Yes it does as some Bios check the vbios for supported list of cards
