Firmware pack for the ASUS GL503VS gaming laptop, board revision 2.0, containing both the system BIOS and the EC (embedded controller) firmware. Having both lets you restore a board where a corrupted BIOS chip or EC fault stops it powering on, charging or running the fans. Flash each image to its own chip with an SPI programmer, after first reading and saving the original contents. Check the 2.0 revision on the PCB and that each image size matches its target 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 @biosarchive. Enginerys does not host this file.
