BIOS dump for the Acer Aspire One D257 netbook, Quanta ZE6 platform board DA0ZE6MB6E0, revision E, compressed to about 900 KB. The DA0…MB6… pattern is Quanta's board numbering, with the final letter showing the revision. Use the image to reprogram the SPI flash with a programmer when the netbook fails to start after a bad update. Back up the existing chip contents first, match the image size to the flash chip, and check that your PCB is revision E.
