I have a Toshiba Tecra 9100 with dual boot Win2k and WinXP. Installed Liteon LSC245082k CDRW/DVD. On boot, I get IDE 1 error. System boots anyway and when I check device manager - no CD drive. Two methods get it installed 1) Uninstall secondary IDE and re-install - Windows will recognize the drive and auto-install 2) Remove under power and re-install. However, on next boot, same problem.
