Working BIOS for the GK5CN6X motherboard revision 1.1, with images for the chips at positions U8 and U20, in a 15.4 MB RAR archive. Two designators suggest separate flash devices, so each file must go to its matching chip and not be swapped. Technicians write such images with an SPI programmer to recover boards with corrupted firmware. Read and save both original chips before writing, confirm each image size suits the capacity of its target, and check the PCB revision matches 1.1.
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.
