RAR archive labelled as an 8 MB BIOS for the Compal LA-D707P board, platform CDL50, although the archive is about 21.7 MB. That suggests it holds several files, such as multiple dumps or tools, rather than a single image. Look through the contents and pick the file whose size matches the 64 Mbit flash chip on the board. Confirm the LA-D707P marking and revision on the PCB, back up the original chip, and verify after programming. A dated, tested version is listed separately.
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 @biosarchive. Enginerys does not host this file.
