I don't know if Ubuntu has RAID drivers for this particular device on the
setup, I wouldn't know how to use them if it did either. I do know that
Ubuntu has some RAID drivers in the installer though.

Actually I didn't know about dmraid, but apparently it "discovers,
activates, deactivates and displays properties of software RAID sets (eg,
ATARAID) and contained DOS partitions" and supports "Silicon Image(tm)
Medley(tm)". I'm not sure if that means it will support Silicon Image 3112A
fakeraid or not, but it could be interesting.

My friend found a forum posting in which someone explained how they did this
with Ubuntu. It looked pretty complex. He's not willing to go to those
lengths. Maybe it can be done more easily than the posting described, I
don't know. Here is the post:

    For dual booting, why not using Partition1 of each disk for RAID using

My friend doesn't think this is possible, he said that once a drive becomes
'RAIDed' the whole drive becomes 'RAIDed'.

Thanks for the input.
