    Is there any good utility or windows program to downgrade the uefi bios

    I upgraded the bios to the latest 2.20 bios and the pci express graphics cards no longer work. Asrock is telling me they need to send a new bios chip.. i can boot with the onboard video but not with any addin cards, get error code a9 and other errors depending on which boot sequence i actually check the code for.

    I want to downgrade the bios... how can i do this?
