Sata drives on a P5W DH Deluxe

Quick question--I don't remember where I read it at, but can I disable the ez-raid function (which already is) and use one of those ports as an intel ICH port? I already have the three Intel sata connectors filled up w/ three sata disc drives, and wanted to use this along with my Pioneer IDE drive. That is the way to go instead of using the JMicron?

Thanks for any help
