BIOS version 1.05 for the Acer Aspire 7250G, configuration E458G75Mikk, supplied in a 1.03 MB ZIP. The configuration string refers to a specific factory build, so compare it with the base label before use. The firmware helps recover a board stuck without display after failed flashing, through the vendor flasher or an external SPI programmer. Unpack it to check the image type, read out and keep the original chip data, and make sure the file size equals the chip capacity before programming.
