AFS POSITIVO ULTRA S400 6-71-W5400-D02

BIOS .rar 17.0 MB Shared

Firmware package for the Positivo Ultra S400, based on the Clevo mainboard 6-71-W5400 revision D02. At 17 MB it is a larger archive that may contain more than a single image, such as several dumps or tools, so review the contents after extraction. Clevo boards carry the 6-71 prefix and are rebranded widely, so match the code printed on the PCB. Use the correct file to reprogram the SPI chip, and keep a backup of the original firmware before writing.

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 @afsbiosfree. Enginerys does not host this file.
