I installed the drivers from the cd and went to realteks site and downloaded their audio drivers. I don't think I have any scsi devices... As far as hardware goes, I have my two sata drives currently in ahci mode, a sata dvd drive, heatsink, vga card, vga switch card (allows me to use the pci-e slot in full 16x when only using 1 vga card), cpu, mobo, and thats it.
