Dell Raid Questions



I'm a software developer but when it comes to hardware I get lost in the
jargon.
I have a few dell Precision machines I got cheap at the auctions, I'm using
as cheap web servers with Win2003 and one with WinSBS 2000, I also have one
with Vista.
They have SATA 80 gig hard drives in them, they are configured in the bios
raid section to use combination mode.
I have several Sata hard drives of the same make and model and I want to set
up a simple raid 1 system for redundancy.
If I try to change the raid configuration to the default auto detect raid, I
get a warning that I may not be able to boot and that I may need to
reinstall, so I have not done so.

My questions are
Will I lose my data if I switch to raid auto detect?
What is raid Auto detect?
Is this a built in raid system?
If so what do I need to do, just plug in 2 disks?

If anyone has any info on Dell precisions and raid I would appreciate any
info you can give
Thanks
