Windows 7 - Gigabyte RAID not working.

Hello, I am attempting to install a RAID 1 setup with 2 WD 320GB SATA drives using the GIGABYTE P67X-UD3-B3 motherboard. The mobo has 2 different built in RAID controllers... the Intel and the Marvell. If I leave the BIOS settings alone and leave it the default of IDE controller mode I am able to see both harddrives and boot into windows. If I change either of the controllers to use RAID I would expect to see another menu on the POST boot that allowed me to configure my RAID array and then keep on with the boot process. When I reboot after changing the BIOS settings on the POST it gets to where it wants to look for the IDE drives then goes to a blank black screen with a curser blinking in the top left corner. I cannot get out of this unless I hard reset or ctrl-alt-delete to reboot. I am then unable to get into the BIOS to change it back and I have to use the CMOS short pins on the motherboard to reset it to factory. Any suggestions on what I can do?
