BenQ Joybook X31

BIOS .7z 860 KB Shared

BIOS firmware for the BenQ Joybook X31 laptop, stored in a small 860 KB 7z archive. The name carries no board number, revision or flash chip information, so the contents should be inspected before use. Small images like this typically belong to older machines with low capacity flash chips, and are reprogrammed with an external programmer when the system fails to POST after a bad update. Confirm the extracted file size matches the chip on the board and save the original dump 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 @biosfiles. Enginerys does not host this file.
