Ignore all the below shit, got everything working now.
Ok, I have a Creative Labs 6X DVD Rom Drive.
I tried hooking it up as a Slave to my HD IDE cable, with the xbox DVD drive plugged into it's original power source.
I have tried booting up a EvoX disc on Mexell and Hi-Val CD-R media, and now on a Verbatim CD-RW with a original Xbox game disc in the Xbox dvd drive.
No matter what I get red/green flashing and the Service your xbox screen. If I try and boot any of these disc's from the Xbox DVD drive (Without PCDVD drive) it boots up like normal then says it does not recognize the disc.

Oh, and the CD-R media I used could be read by my PC, but the CD-RW cannot. I think that meens the CD-R's where not burned right, for whatever reason, but the CD-RW seems to have been burned correctly as my PC cannot read it, but I can see there is data on the disc.
