ummm yes, that is what i will do later because i am kind of over budget by buying a good cpu and ram, seeking for speed to process information. Now, I only want to spend like 20 bucks more to make my old equipments work. I will definately shift to sata in the future. If I cant get the old dvd rom to boot, i will plug 1 pata to on-board and the other to dvd rom, in order to make it bootable. Then the other 2 devices to the pci-ide card. But now i want to hear some suggestions of good pci-ide cards. My goal is to make all the devices bootable.
