Hi, I have an ABIT KR7A-RAID with HPT372 controller. I succesfully tried to build and install the kernel module driver from source: http://www.highpoint-tech.com/hpt3xx-opensource-v131.tgz I installed as well the Raid Manager and I can see the 2 HDDs connected on the controller as a RAID 1 disc. Actually my system (RH9 and now FC1) is installed on a third disc (Primary Master), but on the RAID disc I have several NTFS partitions that are easily accessible. So, it works. But I cannot guarantee that there will not be error while writing on the discs (I have not tried that yet).
