Hi. my pc can't boot-up on the cdrom. the setup is to boot-up first on the cdrom drive then hdd but it continues to the hdd right away. the win-explorer can see the cdrom drive but can't read any cdrom. i did change the cdrom bec i thought the cdrom was dirty but still the problem remains. i did try to uninstall the IDE 2nd channel and installed itself back, did try to load different type of cd, data/audio/bootable. still the problem exists. what could be wrong? thanks.
