BIOS file for the Acer Aspire 7250 on a Pegatron-made motherboard, with AAB70 in the name, which most likely refers to the board or firmware code. The rar archive is small, about 1.01 MB, so the image probably targets a compact SPI flash chip. Pegatron is the ODM in this case, not Compal or Quanta. Compare the codes printed on the PCB before use, keep a backup of the original chip contents, and confirm that the image size equals the chip capacity before programming with a hardware flasher.
