Yes, Toast comes with its own CD driver extension which will probably work. However, the best solution may be to get the Apple universal CD-ROM driver here:

I'm pretty sure you will need to have the main driver version 5.3.1 and all of the other extensions from 5.3.2.

You should also be able to use the CD-ROM without a driver at all if you have a bootable CD in there as it boots from the hard drive. Once it mounts on the desktop, you can eject and use other CDs just fine. It's one of those weird old Mac quirks.
