Here's the type of thing you need at the egg (same as gtvr listed above); it plugs into the back of the IDE drive:http://www.newegg.com/Product/Product.aspx?Item=N82E16812240009&cm_re=ide_adapter_to_sata-_-12-240-009-_-Product
NOTE that this one is so you can use an IDE drive (jumpered to Master) on a SATA mobo port. There is a different model that adapts SATA drives to IDE ports.
sminlal suggested a PCI card to give you an IDE port. Third alternative: you could consider buying an external enclosure that accepts an IDE drive and turn your old drive into an external drive.
