Installing 2 DVD Drives

Hey guys. So im a noob at this and im trying to install two DVD drives one LG one Pioneer. Well the pioneer one is already installed i guess but the LG wont detect when i attatch them both to the one IDE cable. My mobo is a Gigabyte 965p-Ds4 and ive got 2gb ocz ram gold edition and an 8800 gts gigabyte as well … i dont think any of these affect it but i really need help. lol i just want to run the both of them. :bow: :bow: :bow: :bow: :bow: :bow: LOL i honestly need help

checked the jumpers on the drives set one to master one to slave or both on csel (cableselect?)
