Greg: I think you missed my first couple of posts. I have openSuSE running on this machine right now. The issue is: it did not detect hardware the way they are setup - RAID. I want dismantle RAID, if opensuse supports AHCI. Please remember that the LiveCD will have more drivers and power than the distro. I have seen that before and you will find posts online about it. I asked one simple question. If you do not know exact answer, please do not guess it. Otherwise, people who may have replied will hesitate. thanks --- On Tue, 1/13/09, Greg Freemyer wrote:

Does anyone know if AHCI is built into the Linux Kernel that comes with openSUSE 11.1? Please reply.

AHCI is a class of SATA controllers. The basic AHCI functionality is definitely in the kernel.

The reason you need to test is to see if the specific controller / PCI-bus / etc. that you have will trigger the AHCI driver to load and run.

If it does not, it is typically straight forward to get PCI-IDs, etc. added to the vanilla kernel, but that will not help you.

Therefore, I still recommend you test via the LiveCD OpenSUSE provides. It uses the same kernel as the full product and one of the reasons it exists is to allow people such as yourself to perform hardware compatibility tests.

SATA controller cards have different modes. When you change the mode you cause a different PCI-ID to be returned by the controller. That is what triggers different drivers to kick in for different modes of the controller. So that fact that your controller in RAID mode has problems is totally meaningless when asking if it will work in AHCI mode. FYI: In AHCI mode, if you want raid support you have to use mdraid (software raid) and your current raid will be lost.
