Raid on the IP35 Pro (cos I've done it meself )
1. Boot into bios.
2. Go down the settings I think to advanced configuration, onboard devices, change mode from IDE to Raid.
3. Reboot, press ctrl+I when prompted to do so
4. Create your raid array
No worries though - this is all explained comprehensively in the manual and it's pretty straightforward and hard to get wrong. One thing that may be worth doing (may not be depending?) is if you set the raid0 stripe to be 95% of the disks, the last 5% or so you can create a raid1 array and stick your documents in there. In vista it is as simple as going start > username > select all > copy > new folder (in D: for sake of argument) > paste. Windows automatically redirects your default save directories so there's no worries there.
