How to convert a Dumpbios file

1. Run the 3Dfx BIOS Editor.

2. In the Bios Editor click File, Open, In Files of type: choose All files,
then pick the dumped BIOS.BIN file.

3. Without changing anything click File, Save As, then rename the file to ORIGBIOS.ROM 

That's All

Note:
The BIOS Editor is not compatible with some V3 3000 or any 3500 BIOS.
I believe it has problems with the larger ROM size due to the TV functions ???
