EP45-UD3R - Help (raid0 Q)

[garry__]

Hey guys,

 

So I have win7 installed currently on my computer. I wanted to install OSX snow leapard, but to do so I noticed that in my bios settings I have to take away raid and switch the mode to ADHI (I believe that's the one, or something that's other than RAID 0).

 

If I swapped the mode to the correct setting wouldn't my RAID 0 partition be wiped?

 

I was planning on installing on an external USB hard drive, so is there any way to do this without wipping my current RAID 0 install with win7?

 

If anybody has an answer it would be greatly appreciated

 

Thanks guys.
