Almost there, but confused about SATA selection in BIOS

Success!! I double checked all connections and finally powered up.
It went right into the BIOS. It's alive! Temperatures seem to hover
at around 118-125 degrees F. The only problem I had was a noisy fan,
which was screwed to the case but when I relocated it, the noise was
gone. It recognized all the 2GB of memory (2048MB) and the drives.
Now that I am in the BIOS, I will need to go very slowly to configure
it. I am now very confused at all the BIOS settings and particularly
the SATA drives. I really don't know how to configure them. I want
to get the most efficiency out of them and am wondering exactly how I
should configure them. Just two 320GB SATA drives. NO RAID.;; Just a
C and D drive. Per Paul's suggestion, the two DVD burners are on the
primary ide channel as master and slave. Can someone please tell me
how exactly to configure these SATA drives for the most efficiency
since I now need to install the operating system (WIN XP SP1).

Thanks all!
