BIOS firmware for a board code-named STARLORD13_B, Wistron number 15264-1, supplied as a 5.22 MB RAR. The name also includes the token X41DX$BA, likely a firmware or model identifier, but no laptop brand is given. Wistron designs carry five-digit project numbers with a revision suffix like this. Use the image to reprogram the SPI flash with an external programmer, backing up the existing chip first and confirming that both the board number and the image size agree with the hardware.
