Modified BIOS image for ASUS model X415DA, firmware version 303, provided as an 8 MB raw bin file. The name says the onboard RAM has been disabled and that the image has been tested. Modified images like this are typically used when the soldered memory has failed, so the laptop can boot from the SO-DIMM slot alone. Write it to the SPI flash with a programmer after saving the original dump, and keep that backup, because it holds serials and other board-specific data. The 8 MB size suits an 8 MB (64 Mbit) chip.
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 @ITHINKHS. Enginerys does not host this file.
