Working BIOS for the ASUS FX505DU laptop motherboard at revision 2.0, claimed to be one hundred percent working and supplied in an 8 MB RAR, differing in size from another FX505DU dump. Use it to reprogram the SPI flash with an external programmer when the board does not boot or shows no image. Confirm the revision printed on the PCB, read and save the current chip contents before writing, and verify the extracted image size equals the capacity of the fitted flash chip.
