Eteam, as long as the operating system is not installed or saved on the RAID you will be able to access to the data using another motherboard.
If the operating system is included on the RAID, you would need to create the RAID 1 again.
I would recommend you to back up all the information before making any change.
Please make sure to access BIOS and set the SATA mode as RAID before loading Windows.
Would the following steps 'do the right thing' ?
1. On existing system config, convert boot/OS drive from RAID1 to non-RAID (is this simple/easy, or tricky?).
2. Switch motherboards and attain bootable, operational condition.
3. Convert boot/OS drive to RAID1.
The idea is to avoid a Windows re-install (and re-install of all applications and drivers, etc.).
I've done motherboard migration without Windows re-install before, with previous versions of Windows and non-RAID system. But it has been a while, and I don't remember exactly how I went about this, and this was several generations of Windows ago (now at Win 7).
Thanks for your help.

Bob, unfortunately if the OS was installed on the RAID 1, it needs to be install it again from scratch. This is because the chipsets are different and the new motherboard won’t be able to boot from a previous installation.
Since you have a RAID 1, you can try to access on the new motherboard using only 1 of the hard drives. Please set the SATA mode as RAID before trying to boot to Windows.
Here is the user guide for the RST. http://download.intel.com/support/chipsets/imsm/sb/irst_user_guide.pdf
I suggest that you check the information available on this article: Intel� Rapid Storage Technology (Intel� RST) — Moving a RAID volume to a different system
If you set the hard drives as non-RAID, you will lose all you data, so it is not simple/easy.
I understand that you don't want to re-install the Operating system, drivers and applications, but in order to have a good performance, it will be necessary. Since the motherboard is newer, the drivers will be diferents (audio, graphics, chipset, etc)
I would recommend you to back up all the drive information first, and then you may try anything you like.
