Okay, Currently I'm running Redhat 9.0 with a FastTrak TX 100. I just bought a dual processor 1 GB RAM system with a PERC3/DCL card. I'm also getting ready to build a new system using Redhat Enterprise ES 4.0. Has anyone had any enperience with RHE 4.0 with the PERC RAID card? I don't see any drivers for it on Dell's website. I do however see PERC3 drivers for Redhat Enterprise 3.0. Do you think the 3.0 drivers would work with the 4.0 enterprise?
