Working BIOS for the ASUS X550CC laptop mainboard, revision 2.0, stated to be fully tested. The RAR archive is roughly 7.5 MB and contains the flash image for the SPI chip. It is typically used to revive a notebook with no display or a boot loop caused by corrupted firmware, written with a CH341A or similar programmer. Read and keep the original dump first, compare the board revision with the PCB marking, and ensure the file size fits the installed flash chip.
