Can't get buitlt in Cd rom without jumpers to work

Hi,

I recently got a Thermaltake Eclipse DV .
With a built in cd rom drive.
There is a IDE cable attached to the cd rom drive (can't be disconnected), and this cable has only one other connector (which goed to the mobo).
When I connect this cable to my second IDE channel , the computer won't boot because it recognises the cd rom drive as a secondary slave on my 2nd channel without a Master on this channel.

With a normal cd rom drive , there wouldn't be a problem because you can just swith the jumpers, but this cd rom drive is built in like a laptop cd rom drive and I cant find any jumpers.

Please help me , i'm open to any suggestions..
