MIxer440 please check the following thread, you may find the drivers you are looking for. Help plz!! Need DG965RY motherboard drivers
Regarding the Intel® Rapid Storage Technology, the ICH7R chipset support until version 11.7 https://downloadcenter.intel.com/Detail_Desc.aspx?DwnldID=22194
I've tried numerous Intel AHCI drivers for the above specifications and none of them work. It seems that the issue is the OEM txt file and how it identifies the chipset/controller during the F6 installation. I was able to find the original Asus OEM F6 and that seems to work since it has the correct OEM txt file.
I appreciate your help
Thanks for letting us know.
