Duplicate 4.00 MB firmware dump for model 6930p, with no extension and no mention of board number, revision or BIOS version. Keeping two reads lets a technician check consistency: if both files differ, one may be a bad read. Open it in a hex editor or the software bundled with a programmer such as a CH341A or TL866 to inspect and flash it. Before relying on it, match the model on the machine, preserve the original chip contents, and verify the chip size is 4 MB.
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 @biosfilebins. 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 →
