this is what I find in the following link but I do not know what the Intel RST user interface is that I am supposed to be able to access while in windows. Is that a program that is intalled if I download latest RST? will I disable or affect Dell BIOS if I download latest RST and replace RST that came with system?

General information
RAID migration overview
A RAID migration allows you to convert a RAID-Ready system into a RAID 0, 1, 5 or 10 configuration, or from a RAID 0, 1 or 10 volume to a RAID 5 volume.
If you have a RAID-Ready configuration, you can add any SATA hard drives necessary and use the Intel® Rapid Storage Technology user interface to start the migration. The migration does not require a reinstall of the operating system.
