Hi,

long time ago there were some video cards supported in flashrom. They
are not much different to other supported PCI(E) programmers in
flashrom. After all, they are just an interface to a flash chip like a
network card is for its boot flash.
The problem is that no one cared any longer for graphics cards and that
the interface changed and became way more complicated.

So "making flashrom to look at * card in order to flash the bios of it"
does not cut it. You need to reverse engineer the correct access
pattern and reimplement it in a flashrom programmer module.

Flashrom to flash video cards

Hi, thank you very much for your reply. I understand that flashrom
currently doesn't have the posibility to access the pcie slot, for example,
and detect the chip on the vga board in order to write it. However i found
a flashrom, apparently modified for ati vga cards...do you want me to send
it to you and check it?
