first question is why do you thinkn you need to update your video bios? it is extremely rare that anyone would ever need to play with the firmware on a vcard..
when i play wow i sometimes get crashes to a blue critical error screen that tell me there is a problem with nv4.dsp and that i should contact my hardware vendor. So i contacted evga and they told me to update my bios for bug fixes.
Maybe they meant drivers, not a bios/firmware update
