BIOS archive for Quanta motherboard DALGAQMB8C0, revision C, which also carries the project code QL9S05. The name gives no laptop brand or model, so identify the target from the board itself. The 7.37 MB RAR should contain an SPI flash image for reprogramming the BIOS chip after corruption or a bad update. The DA...MB8 pattern is Quanta's ODM numbering. Verify the board number and revision on the PCB, save a backup of the original chip, and confirm the image size matches the flash capacity before writing.
