Firmware dump for the ASUS X550CL laptop mainboard, revision 2.1, supplied as a 3.80 MB RAR archive. No chip size, version or status is given in the name, so inspect the contents before use. A dump like this is written to the SPI BIOS chip with an external programmer to revive a board that shows no display or loops on power. ASUS X550 series boards came in several revisions, so compare the revision silkscreened on the PCB, save the original chip contents, and confirm the image matches the flash capacity.
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 @fixtronix. Enginerys does not host this file.
