Disable RAM onboard Asus N551JK — BIOS

ASUS N551JK firmware altered to disable the onboard RAM, intended for boards where soldered memory is defective. The name gives no board revision, so compare the image with your original dump before committing. With this BIOS the laptop relies only on the SO-DIMM slot, avoiding replacement of BGA memory chips. The 980 KB ZIP archive contains the file to be programmed directly into the SPI chip with a CH341A or similar tool. Always save the original contents first to preserve serial number and LAN MAC information.
