Cd drive


In Runtime
I'm currently having a problem with my CD drive I installed. It got it from another computer so no installation CD. The problem is I had a DVD drive in the master spot for awhile and it works great but now I want the CD drive in the master and the DVD in the slave. Only the master is working. I need to go into the driver folder or something but I don't know the commands to get there. Please help anyone Thanks.
