I have a 880G+SB850 board, a DVD writer on SATA port 5, and a ST96812AS and Vertex 2 on ports 1 and 2. I switch Ports 1-4 to AHCI mode, but it still uses IDE mode (it identifies the drives with an IDE: prefix in the BIOS), and I still can't use the OCZ SSD Toolbox (because it's in IDE mode). I thought maybe one of the drives is forcing it into IDE mode through some error, so I unplugged it until the only drives left were the DVD drive and one of the hard drives, but the IDE problem still persists. Has anyone encountered such a problem?
EDIT: just updated the BIOS. No luck.
