My operating system is WinXP Pro. I have two DVD+RW/-RW/CD dual layer drives connected to the secondary IDE port. Both drives used to autorun CD's when installed, but now, neither drive recognizes the autorun feature of CD's. I knew where the switch was when I used Win98, but I can't locate it in WinXP. Can someone point me to this switch? I would like to restore this feature to both drives. Thanks.
