I just purchased a MSI P55-GD65 motherboard which has an onbaoard Intel RAID controller I plan to use (the mobo also has a JMicron RAID controller -- not sure why both are on the mobo?) when building a new PC. I've never set up a RAID array before, so wanted to confirm a couple of things before I do it:
1. I want the PC to boot from the RAID array, so I believe I must activate the RAID array via BIOS before installing the OS (which will be W7). Right?
2. When installing W7 (another "first" for me), will I need to do that "install an optional RAID driver" step that has been required in prior Windows versions?
3. I was planning to configure an array of two drives in 1+0 mode. I realize the performance would be better if I used 4 drives, but I have only two at present. The mobo manual says I need a minimum of 4 drives for 1+0, but I thought (from reading elsewhere) I could do it with only two. I've asked MSI about this, but since the controller is Intel I thought I might get a better answer here. So ... is it possible to configure only 2 drives in 1+0 mode?
4. Would it be possible to set up a RAID 1 array now, using those 2 drives ... then later add 2 more drives and change the configuration to 1+0?
Again, this RAID array will be the only hard drive in the system -- I'm not installing the OS on a stand alone drive and then "adding" the RAID array to it.
Thanks for any help.

Yes enable RAID in the BIOS and Ctrl + I to setup the Array.

No however you can load the newer drivers at the start or after W7 is installed.

No you are likely talking about the Matrix feature:

Going by the help file in 9.5 you can only change to a RAID 0 or 5 from a 2-disk RAID 1.
Change type from - To
2-disk recovery volume - 2-disk RAID 1
2-disk RAID 1 - 2-disk recovery volume
- - 2-disk RAID 0
- - 3, 4, 5 or 6-disk RAID 0
- - 3, 4, 5 or 6-disk RAID 5
2-disk RAID 0 - 3, 4, 5 or 6-disk RAID 5
3-disk RAID 0 - 4, 5 or 6-disk RAID 5
4-disk RAID 0 - 5 or 6-disk RAID 5
4-disk RAID 10 - 4, 5 or 6-disk RAID 5

Hi There
I also have the GA-P55M-UD2 board. I can not get Windows 7 64-bit to get past the hard disk choice box. I have built a Raid-1 array in the BIOS, and have loaded the driver from the Gigabyte site (to get the latest). All I get is the 0x8030001 error no matter what I do. Ignoring the driver loading is not an option as the disk set doesn't appear there. I see from the above that there was no clear answer to the problem. Do you have any more that might help. Thanks.

I need to (and will) update this thread to show my original question was in fact answered. I was able to configure the RAID array in the BIOS and subsequently load W7 64 bit, without much difficulty. I hit an initial snag in the BIOS setup because I there were two RAID controllers listed (both disabled by default) and no clear indication of which was the JMICRON and which was Intel's. I wanted to enable the Intel but accidentally got the other one by mistake. So then I didn't see the choices I expected to choose the array type. But once I went back and enabled the right controller, the rest was smooth and easy. The RAID array was build by/in BIOS, then I installed W7 from disk. No problem.
The only kind of strange thing is that Windows 7 limited me to only two partitions (and I wanted to create 3). I'm not sure if this was somehow related to the underlying RAID array or what ... but it's not really a problem at this point, for me.
So ... this probably isn't any help to you, but that's the story. Good luck!
