BIOS package for the ASUS X550LD laptop, board revision 2.0, bundling the system BIOS together with the KBC (keyboard controller, i.e. embedded controller) firmware in a ZIP archive of 3.26 MB. Having both images lets a technician restore a board where the BIOS chip and the EC flash are corrupted or mismatched. Write the image with an SPI programmer such as a CH341A, but read and save the original chip contents first, and confirm that the revision printed on the PCB is 2.0 before flashing anything.
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.
