BIOS firmware for the K55VD laptop, board revision 3.1, marked as tested and working. K55VD is an Asus model, though the name gives no further detail. The 3.68 MB ZIP holds an image for writing to the SPI flash chip with an external programmer to recover a board that will not post or boots to a black screen. Verify the revision printed on the PCB reads 3.1, back up the existing chip before writing, and confirm the image size matches the chip, otherwise it will not fit.
