wants to transfer files to/from a CD whatever twould be best to be on different controllers. Maybe that's why your system is working just fine. LOL
I assume that you don't also have a RAID controller on the mobo.
My system, Shuttle main board, AMD 2400+ XP 2 Gig processor, 512 Meg RAM, Win-XP. System running perfectly.
I have two HDs and two optical drives, CD-RW and DVD-RW. I currently have the HDs on the primary controller and the optical drives on the secondary controller. I think I read somewhere that the preferred method is to have a HD and an optical on one controller and another HD and optical on the other controller.
Is there a difference?
