BIOS firmware for a Quanta G7A board, number DAG7AMB58C0, revision C, with 086AA likely being a part or version code; the laptop brand and model are not stated. Quanta uses the DA0 or DA prefix plus project code and MB revision characters in its board numbers. The 8.76 MB ZIP is used to reflash the SPI chip with a hardware programmer. Back up the original chip, confirm the board number and revision on the PCB, and check the image size against the flash chip before writing.
