I did a search, but could not find what I need. A proprietary driver might be the better choice...
EDIT: Speaking of which, I went to Driverguide.com as I had originally planned on doing, and downloaded what I thought might be the driver for the DVD-ROM. When I downloaded a zip file for the drive's use, I saw a driver called "SSCDROM.SYS". The readme file was copyrighted in 1996 by Samsung.
