BIOS archive for the ASUS K42JR at board revision 3.2, marked DIS for the discrete graphics version, with a 4 MB flash image, packed as a 3.08 MB RAR. The DIS note means it is meant for boards with a dedicated GPU, not UMA builds. Technicians write this dump to the SPI BIOS chip with a programmer to recover a laptop with no boot or corrupted firmware. Confirm the revision on the PCB matches 3.2, save the original chip contents first, and check the image is exactly 4 MB for the chip.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
