SPI BIOS dump for the Acer Aspire E1-472 built on a Wistron board numbered 12243-1M. Wistron marks its boards with a five-digit project number plus a -1M style suffix, usually printed on the PCB near the model code, so match it before flashing. The 8 MB image fits a 64 Mbit flash and likely includes the Intel ME region along with the BIOS. Save the original contents, then write it with a programmer to recover a bricked unit.
