Modified BIOS for the ASUS UX51VZ, revision 2.0, designed to turn off the soldered onboard memory. It allows a Zenbook with a faulty memory chip to boot using its SO-DIMM slot, instead of replacing BGA DRAM. Apply it with an SPI programmer directly on the flash chip, then install a known-good module. Confirm the board revision 2.0 on the PCB, keep a read of the original firmware for restoration, and verify the image size matches the chip before writing.
