OK, First I disabled the VIA RAID setting on the onboard device in the BIOS . It was looking for standard IDE devices and I was installing SATA HDDs. Then after hunting about on the ASUS download site I finally foun the correct driver(they could make that a little simpler!). Then, in the BIOS I set the IDE configuration I set the OnBoard IDE Ooperate Mode to enhanced, next switch the Configure S-ATA as RAID to yes. And lastly, this is the part that wasn't in the manual, it has an option to make the RAID bootable and it has to be set to yes or it just didn't work. I rebooted and and had it load from the CD and when the time was right I pressed F6, installed the right driver, and away it went. Now though I just noticed that my P4 with hyper-threading, isn't. I am only seeing one CPU on the device manager screen. Any thoughts? I installed a test of Service Pack 2 from Windows heard anything about it?😀
