I have tried adding an Acer cdrw to my system (an amd 333 mhz, 64 mgs ram, running windows 98). After I have installed the hardware and rebooted, the computer recognizes both cds. Then when I try to make any copies it begins the process with testing and then promptly locks up. I have tried installing both cds on ide port #2 as master and slave and also with one as slave to the hard drive on ide port #1. No change. Help?
