Thank you for replying Markus.
This is the first time I've heard the term AHCI.
I did some googling and read up on it. From what I understand, AHCI is a mode you can set in the BIOS.
I dug through the system BIOS and the BIOS on both cards and found no such setting.
The cards are extremely cheap soft-RAID cards that I purchased simply so I could get 8 400GB SATA drives into my server case.
So to answer "What stops you from switching to AHCI?" I would have to say to things:
1. No clue how to enable AHCI
2. If it's a BIOS setting, it appears my cards don't support it.
