I have a ASUS P4B533 mobo that can support 4 ide devices. I am wondering if the Promise Ultra133 TX2 controller. It says its a ATA/133 controller that can control 4 IDE devices. Would this let my computer/mobo handle 4 more devices on top of the Motherboard? It goes in a PCI slot. If i get this, will it allow up to 8 IDE devices being connected? Thanks for any help.
