Actually, it is that simple if you have internal scsi disks and this is more of an issue of the external wide scsi connector than a kernel issue. Just make sure that you have a properly configured kernel. Here is my section for my 2940 UW. controller pci0 controller ahc0 controller scbus0 device sd0 device od0 device st0 device cd0 #Only need one of these, the code dynamically Now -- the other issue are disks in order to fully take advantage of the 2940 UW you need wide scsi devices. The 2940uw will still perform however your thruput will be limited by your scsi 2 devices.
