BIOS image for board A15HC, revision 2.1, prepared for converting the board from discrete graphics to UMA (integrated graphics only). Technicians use such a file when the dedicated GPU has failed and is removed or disabled, so the machine can boot on the processor graphics. Hardware changes such as removing the GPU or setting configuration straps may also be needed, so study the schematic first. Back up the original chip, verify the PCB revision, and confirm the image size matches the flash.
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 @biosfiles. Enginerys does not host this file.
