Putting two SSD's into a RAID configuration

[Mr_Pie_Guy1234]

Gigabyte GA-Z77X-UD5H board
2 x OCZ Agility 3's

If I switch from AHCI to RAID inside the UEFI, the drives aren't picked up inside the installer, so I can't change anything with the drives from disk utility. If I switch to AHCI, then go back to disk utility, they are picked up like normal. I know that you can set up a RAID from inside disk utility, but I'd like to use the motherboard's RAID utility instead of Apple's, because it has more customizability. How do I get the installer to pick up my drives?

I've watched that tutorial already, but I said that I wanted to do it from the BIOS instead, because it would allow me to set up more than one raid array using those two drives.
