I am trying to set up Raid 5 using a Promise SX6000 controller with a ASUS A7V333 MotherBD. The motherboard does not have the build in promise controller. The problem I am having is using an AGP vidio card. It will not boot with an AGP card installed. I tried two different cards. It works fine with a PCI vidio card. Promise told me it was a motherbd bios problem. I up dated the bios, no change. Anyone have an idea as to what may be causing this and how to work around?
