no, cd roms have jumpers to. What you might try, is change it to Secondary Master, and make sure that the cd-rom has the first IDE connection to it, then the second connector to your other cd-rom drive.

I had a HD once that I had connected to the second IDE connector (last one) and for some reason, the HD would load then stop, load then stop. I chnanged it around so the HD was on the first connecter then it worked perfectly.

GIve that a shot though.

Ah you beat me to it striek
