BIOS image for the ASUS X507MA laptop, board revision 2.1, packed as a 5.68 MB RAR archive. Such a dump is used to reprogram the SPI flash chip on the motherboard with a hardware programmer, for example a CH341A with a clip, when the machine fails to post or the firmware is corrupted. Read and save the original chip contents before writing anything. Confirm that the revision printed on the PCB is 2.1 and that the image size matches the capacity of the installed flash chip, otherwise it will not fit.
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 @biosarchive. Enginerys does not host this file.
