Talonman plug only the drives you want your OS to be on for now, i'll make things easier.
Make sure you get the drivers from the Intel website
http://downloadcenter.intel.com/Prod...ProductID=2101
There are 2 downloads you need.
1. RAID/AHCI Software - Intel® Matrix Storage Manager (5615KB) 7.8.0.1012 11/9/2007
2. 64-bit Floppy Configuration Utility for Intel® Matrix Storage Manager (322KB)
Create a floppy with the #2 driver, you will need this when installing Vista64, you will see an option for this on the bottom at the point when it asks you on what drive you want to install Vista.
Set RAID in the BIOS save settings, reboot, make sure also you are not overclocked as this can add to install issues.
When the system is rebooting you should then see the Intel RAID setup screen, enter it by hitting CTRL-I, setup your RAID partitions.
I'll be back in a couple of hours, I'll help you if youre still stuck.
I saw you call for help in the overclocking part2 thread :)
