Acer Aspire One D250 netbook BIOS, named AOD250, inside a 778 KB RAR archive. Beyond the model, the name gives no version, board number or flash size. The archive may contain a raw chip image, a vendor update package, or both, so inspect it first. For a dead or bricked unit, the raw image is written to the SPI flash with an external programmer. Read and keep the original chip contents first, and make sure the image length matches the chip capacity.
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.
