Thank you for your time. heartbroken_1968a......Which jumper settings did you SELECT on the cd-roms ?
Which IDE cable did you connect the new cd- rom to ?

Let us know

dl65  Yup as stated above, please check the jumpers, please check that you in fact have POWER going to both, and that you did not loosen the connection at the motherboard. CheersI used same IDE cable which was CONNECTED to existing cd-rom drive.That cable had extra connenector.Yes i removed the connections IDE cable (connector) from mother board and put it back once i hookedup CDR-ROM drive. I put jumper for slave/ master in existing old cd-rom drive in center.
Rahul........Your description of how you set the jumper isnt really clear ....so here's what you should have done ........
The existing cd drive should have its jumper set as the master and it should be plugged into the plug at the end of the IDE cable .........The new cd drive should have its jumper set as the slave and the cd should be connected to the plug in the MIDDLE of the IDE cable. You must also be sure the 4 pin power plug is plugged into each cd drive .......
