I would like some-one to say that this is no longer supported, or something. I have moved on, so I guess - windows 1, dmraid 0? I am about to change hardware, and still want to use chipset RAID. Are there any chipset RAID that work so I can multi boot? My VIA used to work, then a version or 2 later #!!#$ . I would still be very happy for a resolution. Do you support AMD RAID chipset?
