Tested BIOS image for the LG R58 laptop, Quanta mainboard DA0QL5MB8E0 revision E, compressed into an 841 KB rar; the name marks it as tested and working. Quanta, the ODM, uses the DA0 prefix for its board numbers, printed on the PCB itself. The dump is meant for reprogramming the SPI BIOS chip with a programmer such as a CH341A when the original firmware is damaged. Save a copy of the existing chip first, check that board number and revision E match, and ensure the file size equals the chip capacity.
