BIOS file for a Mercury branded board labelled Pig31u JD, marked as world and ok, suggesting a working dump without a regional restriction. At only 381 KB the archive likely holds a small image, so check the flash chip size carefully; older desktop and some motherboards used 256 KB to 512 KB chips. No board revision is given, so verify the marking on the PCB. Read and keep a backup of the existing chip before writing with a programmer, and do not force an image that does not match the chip.
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 @jdbiosworld. Enginerys does not host this file.
