I > have searched the net I have Intel D975XBX2 with two on-board SATA RAID controllers: one is Intel Matrix and the other is Marvell storage. I have FreeBSD 6.2 with RAID-5 using Intel Matrix Storage. It seems to work fine. When you set it up, you first have to create a RAID array. When your machine boots, right after (or before?) you see the screen that takes you to the BIOS configuration, you'll be prompted to press Ctrl-I (IIRC) and you'll be taken to RAID controller configuration screen. It's really straightforward how to create a new array. Then, when you boot FreeBSD, you should look at dmesg output. Mine looks like this: ad4: 305245MB <Seagate ST3320620AS 3.AAJ> at ata2-master SATA150 ad6: 305245MB <Seagate ST3320620AS 3.AAJ> at ata3-master SATA150 ad8: 305245MB <Seagate ST3320620AS 3.AAJ> at ata4-master SATA150 ad10: 305245MB <Seagate ST3320620AS 3.AAJ> at ata5-master SATA150 ar0: 915729MB <Intel MatrixRAID RAID5 (stripe 64 KB)> status: READY ar0: disk0 READY using ad4 at ata2-master ar0: disk1 READY using ad8 at ata4-master ar0: disk2 READY using ad6 at ata3-master ar0: disk3 READY using ad10 at ata5-master FreeBSD installer asked me what drive I wanted to install it to: ad4, ad6, ad8, ad10, or ar0. Of course, I chose ar0. (The second on-board RAID controller, Marvell 88SE6145, seems to be unsupported under FreeBSD 6.2, unfortunately. It gave me quite some trouble. But that's another topic.)
