VBIOS file for a Sapphire Radeon HD 7790 with 2 GB of GDDR5 memory, tagged with the Sapphire/AMD board number 109-C58247-00A_02. That 109- number is printed on the PCB and is the best way to confirm a match. Technicians use such a file to recover a card with corrupted firmware using ATIFlash or an SPI programmer on the BIOS chip. Back up the existing image first and check that memory type and size agree, since a wrong VBIOS can leave the card without output.
