BIOS archive for Quanta board DAZGUMB1AC0 revision C, an 8 MB image for a 64 Mbit SPI flash. The DA plus MB code pattern is Quanta numbering, while the name does not give the laptop brand or model. The image is used to reprogram a corrupted BIOS chip with an external programmer when the board does not boot or shows no display. Back up the original chip before writing and confirm the board number and revision C on the PCB match.
