I am rebuilding an old PC (P 100) for a friend and I can't see my CD drive in the BIOS or Windows. I have tried several known good drives and cables, but still nothing. I have tried to slave it, CS it, and master it and I still get no result. I can place my HD on both the primaary and secondary IDE's and the hard drive can be seen. The CD cannot be seen on either. It was working in the past. Any help would greatly be appreciated!
