BIOS dump reported as working for the K46A notebook on Quanta mainboard DALL3AMB8E0, revision E, delivered as a 1.32 MB ZIP archive. The board code follows the Quanta DA-prefix scheme. A tested image like this helps recover a board stuck with corrupted firmware when it is written directly to the SPI flash chip using a programmer. Keep a backup of the existing chip contents in case serial or licensing data must be restored. Also verify that the image size equals the chip capacity before writing.
