An 8 MB BIOS image for the ASUS X550LD laptop, motherboard revision 2, marked as tested and working. The size matches a 64 Mbit SPI flash chip, a typical size for Intel Haswell-generation boards. Program it with an external programmer when the board shows no display or fails to boot because of corrupted firmware. Check that the PCB is revision 2.0 and the chip capacity is 8 MB. Save a dump of the original chip first, because it may hold the serial number and other system-specific data you may want to restore.
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.

Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
