Here's my scenario
1 640GB drive (system) attached to SATA III
1 DVD drive attached to SATA III
Installed Windows 7, all is good in the world.
Now I'm ready to add 2 pairs of 1TB drives in RAID0, all is NOT good in the world. Attached the 4 1TB drives to the remaining Sata II ports. Changed BIOS from IDE (oops, should have been AHCI but whatever) to RAID. Rebooted, CTRL-I to Intel raid management. Configured 2 x 2TB RAID0 sets. Left system drive 640GB alone. Went back to main BIOS, can see both RAID sets (by name) and the 640GB drive, set 640GB as primary boot device.
However, system will no longer boot (operating system not found.) Hmm..really? Change back to IDE instead of RAID in Integrated Peripherals/SATA control mode and machine boots again, but of course the RAID controller is now disabled.
What am I missing here, what is the sequence of events and settings to configure an existing standalone boot drive and add RAID sets to the system? I realize I will probably need to install drivers for the RAID controller in Windows but I can't even get there as the original system drive either isn't active after switching to RAID controller or not the primary boot device.
TIA!
