Working BIOS dump for the ASUS K52JR laptop with board revision 2.3A, in a RAR archive of about 1.94 MB. It is meant for restoring a corrupted flash chip on a motherboard that shows no picture, no POST or restarts at power-on. Technicians normally write it with an external SPI programmer, using a clip or after desoldering the chip. Read and keep the original contents first, and check that the revision silkscreened on the PCB matches 2.3A, since ASUS changed hardware between revisions.
