My answer is about the possibilities off success with this configuration.
The PC will have an Gigabyte GA-H97-D3H motherboard, obviously with the Intel H97 Chipset.
My idea is about to configure a Windows Server 2012 r2 , with 2 1TB SATA HDs into RAID 1 for a client.
The vendor don`t offer Windows Server Drivers for this model of mobo, but Intel heve Win Server drivers for de Intel RST.
Is an error to supouse that it will work?
Thanks in advance and sorry about my english.
This will depend on your motherboard maker, the Intel drivers might be able to help on this matter; however, they are not validated to work on desktop chipset.
You could try testing drivers linked below:
