Onboard RAM disable firmware for the ASUS X450LD mainboard, revision 2.1, packed as a RAR archive. The modification lets a board with failed soldered memory boot using only the SO-DIMM slot, avoiding a BGA rework of the memory chips. It is programmed directly into the BIOS flash with a programmer, then a working module is fitted. Make sure the revision printed on the PCB is 2.1, read and store the existing chip contents, and compare the image size with the chip capacity before writing.
