I had no trouble installing Win 7 RTM, but I did turn off the JMicron controller (The GSATA 4 port one), because it's useless. I am using BIOS F8 (no longer available, see other post be me), so I would suggest you use F9E BIOS, there is updated BIOS RAID code for the ICH10R from F8 onwards. I'm currelntly running the Vertex as C: with the Operating System on it, D: drive of 500GB RAID1 for Documents and Data and E: drive of 500GB RAID1 as a scratch area. The DVD writer drive takes up the final 6th port on the ICR10R. The driver version I'm using for the ICR10R is 8.9.0.1023.
I had previously installed the Win 7 beta onto the 4 x 500GB disks running as RAID10 without any problems. The Vertex certainly makes the system much faster!
