2nd cdrom

recently had cdr-rw installed and now have reinstalled my old cdr
as a second drive.
I have set the jumper pins and connected cable but when I startup I get a clicking noise and computer wont finish startup.
when old cdr is disconnected all is well.
Do I have to change any settings in bios?

 

bios settings shouldn't cause the computer to lock as you describe, but who knows.

I would suspect the cable, either bad or connected backwards, the red stripe on cable must go to pin 1.

Also double check that the jumpers are not set the same as the other device, only one master and one slave per cable

Also whatever ide channel you are adding the drive to should be set to auto or cdrom in the bios.
