RAR archive with a BIOS dump for a laptop board tagged LGR58, Quanta board number DAQL5AMB8C0, revision C, with a 1MB image stated in the name. Quanta, a notebook ODM, uses the DA prefix plus project code and MB for the main board, here project QL5A. Technicians use such an image to reflash the SPI chip with a programmer such as a CH341A after corruption. Back up the original chip first, confirm the chip is 1MB, and check the board number and revision on the PCB.
