I found this on the IGM website. Not sure if this will work for all, but it is a firmware upgrade for the Hitachi DVD-ROMs that came with most older IBM Aptiva computers. So, it might support most of the GD series DVD-ROMs. Not 100% sure though. Let me know if this works for any of you (I don't have a diskette drive right now so I can't try it out).
The following files are found inside the driver download file.
