BIOS firmware for the Acer Aspire 4250 laptop on the Quanta DA0ZQPMB6C0 mainboard, revision C, stored as a 4.78 MB RAR. DA0 numbers follow the Quanta scheme, with ZQP as the project code and the trailing letter giving the PCB revision. The image is written to the SPI flash with a programmer to fix no-boot or black-screen faults caused by a corrupted BIOS. Verify the revision silkscreened on the board, compare the image size with the chip capacity, and dump the original chip first.
