How do I disable the RAID setup prompt

[Kryhs]

I've done it before, and I can't seem to find it in the manual.

The part I'm talking about is where during the booting process it says "Press shift f4 or something to setup a RAID" and it stays there for 5 seconds or so, I don't need and just want to turn it off.

Edit: Spelled Phoenix wrong

Depending on BIOS version, it is usually under the
"Onboard Devices\Advance" setting.

Then DISABLE the "Onboard Raid controller" (i.e. Promise, Silicon Image, etc..)
