I have the GA-K8NXP-SLI by gigabyte and it has 4 sata controlled by Nvidia nforce4 chip and 4 sata controlled by the sli3114 chip ... i can't seem to only use the nvidia sata (they are yellow) and not the sli3314 sata (they are red). I tried to do what gigabyte tech said but i ened up making my sata drive inacessable because it became non-basic drive ... anyone use all 8 sata on this board ?
