Working BIOS backup for the ASUS X750JB, board revision 2.0, delivered as a RAR archive and labelled as fully working. Such dumps are used to restore a laptop with corrupted firmware by programming the SPI flash directly, typically with a CH341A or similar reader and a clip or desoldered chip. The name does not state chip capacity, so check the image size against the flash marking. Confirm the PCB revision and back up the original contents before erasing and writing.
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.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
