BIOS image for the Acer Aspire C24-320 all-in-one, with the board number 17569-1 that follows the Wistron numbering pattern, supplied as a 2.94 MB ZIP. Wistron is one of the ODMs producing Acer systems, and its boards carry a five-digit code with a revision suffix. The dump is used to rewrite the SPI flash with a programmer when the unit fails to start due to corrupted firmware. Compare the board code on the PCB, keep a backup of the original chip, and confirm the file 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 @biosarchive. Enginerys does not host this file.
