BIOS for the ASUS K52DR laptop board, revision 2.2, in a version that uses the ATI 216-0774007 graphics chip. The name gives a 2MB image, which corresponds to a 16 Mbit SPI flash part, and the RAR archive is 2.28 MB. Repairers use such a dump to bring back boards that power on without video or have a corrupted firmware region. Verify the GPU marking and board revision before use. Always read and keep the existing chip contents before writing the replacement image with a programmer.
