NVidia RAID with SAS RAID
 

Howdy All,
Found a little problem with my new machine. It would appear one cannot run SAS raid and NVidia raid at the same time. I can get one or the other to work just not both. Each of these is on the MB.
Equipment:
Asus P5N64 Pro 790I
Core2 Extreme Qx9770
4 gigs Corsair ddr3 2000 (pc16000)
Dual GX280 by XFX
2 Ultrastar 15K rpm SAS HDs
2 Raptor 10Krpm SATA HDs
Cooler Master 1250W PS
Zalman 9700
Thermaltake Armor Case
various other attached equipment.....

Any advice greatly appreciated.
