I am setting up a system using an Abit AG8 (specs) pictured here. This MB has 4 headers for SATA drives but only has one IDE (ATA100?) connector which I have connected an optical drive and a ide drive. I would like to add another HD and Optical drive to the system. What do I need to do? PCI ATA controller card? SATA-> IDE converter (such a thing)? thanks for your help.
