BIOS dump for the Acer Aspire E1-472 on a Wistron 12243-1M mainboard, with the ME region cleaned. A clean ME lets the Management Engine initialise fresh, which helps when a used dump causes slow boots or shutdowns. The zipped binary is written to the SPI flash with a programmer such as a CH341A. Match the 12243-1M number on the PCB, read and keep the original chip contents first, and verify the image size matches the flash capacity before writing and booting.
