BIOS image for the ASUS K42JA laptop, revision 2.0 board, sized for a 4MB flash chip and described as working and tested. Delivered in a RAR archive, it is used to restore a dead or corrupted board by programming the SPI chip directly with a programmer such as a CH341A. Before flashing, back up the original chip contents, confirm the board revision on the PCB is 2.0, and make sure the chip is a 4MB part, since an image whose size differs from the flash capacity will not fit or work correctly.
