I do have a SIL3114 chipset, and I think it's supposed to be

loading the driver for SIL3112, but nothing appears under /dev/mapper

use my controller's raid?
Your controller only has a bios chip. It has no raid processing
capability at all.
You need to use mdadm. anaconda should be able to let you create to
mirrors and then create a third array that stripes those md devices,

Anaconda doesn't let me create a stripe raid set on top of a mirror
set. And it doesn't detect it when I do it manually.
Also the bios chip presents additional issues. I believe when I don't
have a raid array set up, it won't boot at all. When I have it on
raid10, I had trouble booting, and when I have it on concatenation,
everything works fine, until a drive is replaced. At that point, i have
to recreate the array, as concatenation is not a fault tolerant set, and
at this point I seem to lose all my data.
Is there a way to get it to use the raid that's part of the bios chip?
Something about device mapper?
