BIOS dump for an E1-421 laptop on Quanta board DA0ZQZMB6C1, revision C, in the version with AMD graphics. The 1.48 MB rar is meant for flashing the SPI chip with a programmer to fix a no-boot or no-display fault caused by corrupted firmware. Quanta numbers its boards with the DA0 prefix, a three-letter project code and MB plus revision. Make sure the graphics variant and revision match your board, back up the original chip before writing, and check the image size against chip capacity.
