Lenovo 3000 G430 BIOS dump for Quanta board DA0LE6MB6F0, revision F, in a RAR file of 1.14 MB. Quanta is the ODM that uses DA0-style mainboard numbers, and the trailing revision letter should match the marking on your PCB. The image serves to recover firmware by programming the SPI flash chip directly with a tool such as a CH341A. Save the original chip contents before erasing, since it may hold system-specific data, and check that the file size equals the chip capacity.
