BIOS archive for a board code-named Roadrunner, version 1.1, carrying the number 12260-1, which follows Wistron's project numbering. The name does not give the laptop brand or model, so identify the target device from the motherboard silkscreen before use. The 3.49 MB rar should contain an SPI image for flashing with an external programmer. Check the board number and revision on the PCB, make sure the image matches the chip size, and save the original firmware first.
