Need help on CD-ROM driver(s)

Just inherited a 533i emachine which has been through several hands before it came to mine. The CD Rom doesn't exist according to Windows. But if you have a Cd with autorun on it, it works. Otherwise, it doesn't exist when you click on my computer (it is not on that list with floppy on A, Hard drive C, etc.)

Running Win98SE, and all is okay except for the conflict with the cdrom driver when I look at devices. Took the cdrom out and looked at the actual cdrom case to see what cdrom I have. The case says that it is: Samsung CD Master 40E, model SC-140.

However, the driver installed is for a MKEPanasonic CD-ROM Drive. I figured ah ha, someone installed the wrong driver and that is why the cdrom has conflicts and is not recognized. But also have further complications on this.

The Bios seems to recognize it as a OTI-91X Atapi cdrom. don't have a driver for this either.

So, what should I do to clear up all these problems. I would guess that if I got the right driver I could install it. But how do I get to the point where I can find the right driver and make the machine use it?

Any and all help is appreciated! Thanks in advance for taking the time to think about/work out my problem!
