Subject:   Install 8.2-Release AMD64 on Laptop with Raid0
Message-ID:  <1311099631.2262.20.camel@asus>

I have not used RAID before.

I have a laptop (new to me) with windows 7 and RAID0.

I want to install 8.2-Release and retain the Raid0.

I booted the 8.2-Release AMD64 DVD and exited to Fixit.

pciconf -lv shows

atapci0@pci0:0:31:2: class=0x010400 card=0x159b103c chip=0x282a8086
rev=0x05 hdr=0x00
  class= mass storage
  subclass=RAID

I attached portions of dmesg below.

sysinstall shows 3 choices for disk drives.  ad4(600G), ad6(600G),
ar0(RAID0)

I want to use RAID0 and use the entire disk, partitioned by 'A'.

Which disk do I select for installation?
