I have a PII 350 MHZ p.c. that I am trying to install a CD-RW in. The p.c. currently has a CDRom drive and a tape backup drive. The tape backup drive is not working so that is why I am going to remove the tape backup drive and plug in the CD-RW drive in its place. The installation instructions seem pretty straightforward; however, I am a bit confused when it talks about the primary and secondary IDE and the jumper on master and slave, etc. Should I just try putting in the CD-RW in the place of the existing tape backup unit and see what happens?? I would appreciate any input. Thank you!
