Working BIOS for the ASUS X550VX notebook at board revision 2.0, packed in a small 915 KB RAR, so the compressed image inside is probably larger once extracted. ASUS uses its model name as the board marking, so check that X550VX and REV 2.0 are printed on the PCB. Technicians flash such dumps with an SPI programmer to recover boards that will not post. Extract the image, confirm its size against the flash chip, and save the original BIOS before writing.
