VBIOS for a Sapphire Radeon HD 2600 XT with 256 MB of GDDR4 memory on PCI Express, with the number 8002200 in brackets, likely a firmware or board code. GDDR4 versions need their own BIOS, as GDDR3 variants of the same chip use different memory settings. The file is flashed with ATIFlash or written directly to the BIOS chip with a programmer to recover a dead card. Back up the current image first and compare the card's markings with the name.
