Ok, you know it works in 3.1. So copy the dosdriver from the DEVS drawer on your 3.1 installation to the DEVS drawer on your 3.9 installation. Then open the DOSDriver in a text editor. Find the Device line and copy the device it says form the DEVS drawer on your 3.1 installation to the 3.9 installation. Do the same thing for the DOSDriver, which needs to be copied from the L drawer of 3.1 to the L drawer of 3.9. Reboot in to 3.9 and your CD drive should work.
