Disable Onboard RAM Asus X555LD Rev 2.0

BIOS .rar 3.45 MB Shared

ASUS X555LD rev 2.0 BIOS edited to turn off the onboard memory chips, packed in a 3.45 MB RAR file. With this image the system boots on the slot module alone, sparing a BGA replacement of failed soldered RAM. Technicians unpack it and program the SPI flash chip with a CH341A or similar tool. Confirm the PCB revision silkscreen reads 2.0, keep a full dump of the original chip, and check that the image size equals the flash capacity before writing to avoid a non-booting board.
