BIOS dump packed in a RAR for a laptop built on the Quanta board DA0MTTMB8F0, revision F, with the token C45 in the name likely pointing to the model it came from. The DA0xxxMB8xx pattern is Quanta's numbering, so the laptop brand may differ from the board maker. Use it to restore a corrupted SPI flash with a programmer such as CH341A. Check that the board number and revision letter printed on the PCB match, back up the existing chip, and confirm the image size equals the flash capacity.
