Pc Won't Boot-up On Cdrom

[percy]

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.

try a new IDE cable for it.

make sure jumper is set correctly

make sure you are using a known good bootlable cd (test in another box)

Uninstalling ide channel, etc will do no good since it is pre windows

test to see if you can boot from floppy
