BIOS dump from a K401UB main board, revision 2.0, in a 3.76 MB RAR. The name gives the model and revision only, with no brand, EC or version details, though the K401 naming matches ASUS notebooks. A raw dump like this is written to the SPI flash with a programmer such as a CH341A to recover a board that fails to boot. Check the revision printed on the PCB, save the existing chip contents first, and verify that the image size equals the chip capacity.
