BIOS .rar 3.19 MB Shared

Mainboard BIOS for the ASUS X550JX laptop, board revision 2.0, packed in a RAR archive of about 3.2 MB. The name gives no CPU variant, version or tested status, so check the contents before use. A file like this is written directly to the SPI flash with an external programmer to revive a board that powers on but does not display. Make a backup read of the existing chip, verify that the board revision matches 2.0, and confirm that the image size suits the installed flash device.

The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.
