I have that chip built onto my mobo. tried redhat 8.0, mandrake 9.0 debian 3.0a caldera (don't remember version but it was the newest), Lycoris (newest version) and gentoo 1.4. only gentoo redhat and mandrake recognized the drives on the array. mandrake and gentoo would recognize the array, but would trash something on one of the drives, and kill the array (this would happen either after partitioning or installing grub). I gave up after a few hours and ended up just installing linux with the drives not in raid. If you are able to find a way to install onto a raid array, please let me know. Thanks.
