Newbie install question about disks

Hi all

I am installing a new and all Freebsd system (no other OS in it). The goal
is to have a NFS for a network that has 2x200Gb in RAID 1 disks for data.

It has 3 disks:
- 80Gb Seagate IDE for FreeBSD OS alone
- 2xSATA Seagate 200Gb disks in RAID 1 with the ICH7R motherboard chipset
configured SATA II.

and 1 CD-RW.

The BIOS has 3 IDE plugs and 4 SATA.

I install from the CD FreeBSD 6.1 May 2006  (I've tried "i386" and
"amd64", because is a EM64T 6xx)

In sysinstall appears:
- ad0 => HD 80GB  (for FreeBSD OS at complete)
- ad12 => oine of the SATA HD I think
- ad8 => The other SATA HD I think
- ar0 =>  ???????????????  (I suppose this is the RAID isnt'it?)

What must I do?

- Make filesystem for the 3 (ad12, ad8, ar0)?
- Make only for ar0?
- make for ad12, ad8 and not for ar0?
- make for ad12, ad8 and ar0?

I have installed FreeBSD before but not with this configuration and really
I don't know what to do.

Nothing in manual or FAQ about this.

Thanks in advance
