It depends if you're talking about hardware or software RAID.

If you have a hardware raid controller and wish to use hardware RAID, you
need to configure the RAID controller to use hardware RAID 1 and then the
edubuntu install should just see the RAID disk.  How the RAID setup is done
depends on the raid controller, it may include booting off a raid config
cd.

If you want to use software RAID, you don't do anything in the BIOS, you
install edubuntu as normal, then as far as I can recall:

1. When you get to partitioning, choose manual partitioning
2. Partition the two disks, creating an identical partition on each for
   each RAID-1 partition you want to create.  Set the partition type to
   linux/raid.
3. choose Configure software raid.
4. configure new raid array devices pairing off the partitions you created
   above, setting them to be mounted in the right way and with the right
   filesystem.

At one time with software raid you couldn't have /boot as your first
partition (first needed to be /).  This problem is probably fixed now but
it might be no harm to bear it in mind.
