    Hi, I am working on a project to upgrade my Lenovo P71's MXM GPU from a P4000 to something else, and I read from other users here on the forum says that the Lenovo P71's BIOS has a videocard whitelist, and I wanted to test to see if I could change the Vbios from an eBay Lenovo Quadro M620 to another manufacturer's M620 to test the P71's BIOS if it would allow it.

    So, long story short, If anyone could share a Vbios from an HP, Dell, or some other Manufacturer, I would be very appreciative.

    Thanks,
    -SuS

    The only database I know that is of vBios of gpu's: https://www.techpowerup.com/vgabios/
    Had a quick look and couldn't see a Quadro M620 there but doesn't hurt to have a deeper look. Hope it helps

    I HAVE looked at the GPU-Z database and HAVE found an M620 however, I have no way of knowing if this Vbios is from an MXM card or from a desktop card, are the Vbioses the same between these cards??

    No real way to know. If you own a SPI Programmer you should backup the gpu vbios and test this vbios. If something goes wrong. Flash back the backup and avoid problems.

    The only way to know (if it works) is to use a SPI PRogrammer and give it a test

    BTW The mobile Quadro is called Quadro M(obile)620.
    The desktop counterpart is called Quadro P620

    BIOS are particular to their boards and manufacture specs. You can't use another BIOS and expect the same results. So unless there is a GPU upgrade and BIOS update from manufacture doing a DIY isn't advised if your system is still working.
