Modified 8 MB BIOS image for the W9x0LU platform, which the name links to updated CPU microcode, version C4.06. The file has no extension and no brand in its name, so identify the board carefully. W9x0LU matches Clevo's naming, and these images are written to the SPI chip with a programmer. Microcode mods usually add support for other processors. Always back up the original 8 MB chip, as a faulty modified image will leave the board unbootable.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @opendatasheet. Enginerys does not host this file.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
