This document outlines the procedure for manually removing 
the Intel(R) Rapid Storage Technology driver software and
reconfiguring the system to use the native operating system
driver for managing storage controllers.

To complete this procedure, first print this document for use
as a reference. Then, complete Part 1 to determine the SATA
controller mode. Depending on the mode determined in Part 1, 
complete either Part 2A or 2B.

WARNING: Reconfiguring the system may result in the loss of 
data on any RAID volumes currently used by the system. Removing 
the Intel Rapid Storage Technology driver from the boot drive or 
bootable RAID volume may require reinstallation of the 
operating system. To preserve data integrity, back up 
all data before proceeding. 

************************************************************
* Part 1: Determining the System Mode
