Raw 8 MB BIOS image for the ASUS X551MA motherboard, revision 2.0. The name notes a Winbond 25Q64FW flash, a 64 Mbit part that runs at 1.8 V, so the programmer must be set or adapted for 1.8 V to avoid damaging it. The file size matches the chip capacity exactly, so it can be written directly. Read and store the existing contents before flashing, and confirm the PCB revision reads 2.0 before restoring the dump.
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 @laptopbios21. Enginerys does not host this file.
