BIOS dump for the Acer C640, board number 13045-1, labelled PIM81L SUPERB MB. The five-digit plus dash format is typical of Wistron boards. Use the image to rewrite the SPI flash with a programmer after a failed update or when the machine will not boot. Before flashing, compare the board number on the PCB with 13045-1 and save a full read of the existing chip. Check that the image size matches the chip, because a mismatched image will not fit or boot.
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.
