BIOS dump for a board code-named MIHAWK, carrying the Wistron-style board number 15208-2 and the PCB part number 448.06J05.0021, with the label BLUE also present in the name. The 15208 pattern with a dash suffix is typical of Wistron mainboards, a design house building laptops for Dell, Acer and Lenovo, and the 448 prefix is Wistron PCB numbering. The name gives no laptop model, so confirm the board number on the PCB. Save a copy of the original SPI flash before writing, and check the image size against the chip capacity.
