Just wanted to let you know that it is virtually impossible to run ANY PCI/e Raidcontroller on this mobo, as long as the ICH setting is AHCI or Raid. This holds true for any Abit S775 board I have tried, these include old and new QuadGT as well as the IP35 Pro. It won't boot from HDD or CD, unless you prevent the addon card from initializing itself.
So the only solution is getting a big fat multiport addon card so you can disable onboard raid

Edit: Ace, 16.B09 Bios any good?
