82801JI (ICH10) Raid (aka matrix storage manager)

Hi all, I've been looking around on the intel site for a few hours now, trying to find a technical specification for the matrix storage manager metadata fields in the latest ICH10R controllers.

I own one of these, and run Linux. Previous versions seem to have had their signature and metadata located at 1K(two sectors) back from the end of the disk; mine has metadata, apparently correctly formatted such that the current dmraid code understand it [my volumes mount - thats a good start], but set back 2115 sectors from the end of the disk.

So I'm writing an update to the isw ataraid driver in dmraid, and while I have figured out enough by simple inspection of whats on the disk, to get it going - it would be great to have an actual specification so that I can make it as robust and correct for other people as possible.

This bug report https://bugs.edge.launchpad.net/ubuntu/+source/dmraid/+bug/372170 contains more detailed data if anyone cares to look :). But my primary interest is to find some specs on the hardware I have :).

Thanks in advance,
Rob
