Just as I thought. The DVD-ROM drive is installed, and detected as a Samsung DVD-ROM SD-612 under the bios, and is detected in Windows 95 as a CD-ROM under Windows Explorer. The device manager showed it as a DVD-ROM.
Speaking of the analog audio, I had to choose the F: drive while in the multimedia part of the control panel to get it to work. The Riven DVD ran just fine. The analog audio cable is going from the DVD-ROM drive to the AUX input of the sound card.
One other thing I have to mention is that one of my CD-ROM games for MS-DOS, Stonekeep, had some issues with the Goldstar CD-ROM drive at the top of the tower. Certain conversations that take place during the game would get interrupted by the Goldstar drive spinning up. It's not so with the Samsung drive. However, to get Stonekeep to run using the drive installed today, I had to reinstall the program from the disc as it was asking for the E: drive. (Changing the line in the config file in the game's directory didn't help for some reason.)
