This document outlines the procedure for manually removing 
the Intel(R) Matrix Storage Manager 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 Matrix Storage Manager 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
************************************************************

The steps for removing this software differ depending on 
whether the system is running in RAID or AHCI mode.
Mobile systems do not support RAID.

Determine the system's mode by identifying how the Serial 
ATA controller is presented within the Device Manager by 
completing the steps below:

1.  On the Start menu:
    1a. For Windows* 2000, select Settings and then select 
        Control Panel.
    1b. For Windows* XP or later operating systems, 
        select Control Panel.

2.  Open on the 'System' applet (you may first 
    have to select 'Switch to Classic View').

3.  Select the 'Hardware' tab. 

4.  Select the 'Device Manager' button.

5.  From the Device Manager, look for an entry named 
    'SCSI and RAID Controllers'.
    If this entry is present, expand it and look for one of
    the following controllers. If this entry is not present,
    proceed with step 6:
    
    - 'Intel(R)  82801HEM SATA RAID Controller'
      If the controller above is present, the system is an 
      ICH8ME system in RAID mode. 
      Continue with Part 2A below.    

    - 'Intel(R) 82801HR/HH/HO SATA RAID Controller'
      If the controller above is present, the system is an 
      ICH8R system in RAID mode. 
      Continue with Part 2A below.

    - 'Intel(R) 631xESB/632xESB SATA RAID Controller'
      If the controller above is present, the system is an 
      631xESB/632xESB system in RAID mode. 
      Continue with Part 2A below.

    - 'Intel(R) 82801GHM SATA RAID Controller'
      If the controller above is present, the system is an 
      ICH7MR/DH system in RAID mode. Continue with Part 2A below.

    - 'Intel(R) 82801GR/GH SATA RAID Controller'
      If the Controller above is present, the system is an
      ICH7R/DH system in RAID mode. Continue with Part 2A
      below.

    - 'Intel(R) 82801FR SATA RAID Controller' 
      If the controller above is present, the system is an 
      ICH6R system in RAID mode. Continue with Part 2A 
      below.

    - If none of the controllers above are shown, then 
      the system is not running in RAID mode. Continue with 
      step 6 below.

6.  From the Device Manager, look for an entry named 
    'IDE ATA/ATAPI controllers'.
    If this entry is present, expand it and look for one of
    the following controllers:

   - 'Intel(R) 82801HBM SATA AHCI Controller'
      If the controller above is present, the system is an 
      ICH8M system in AHCI mode. 
      Continue with Part 2B below.
  
   - 'Intel(R) 82801HEM SATA AHCI Controller'
      If the controller above is present, the system is an 
      ICH8ME system in AHCI mode. 
      Continue with Part 2B below.

   - 'Intel(R) 82801HR/HH/HO SATA AHCI Controller'
      If the controller above is present, the system is an 
      ICH8R system in AHCI mode. 
      Continue with Part 2B below.

   - 'Intel(R) 631xESB/632xESB SATA AHCI Controller'
      If the controller above is present, the system is an 
      631xESB/632xESB system in AHCI mode. 
      Continue with Part 2B below.

    - 'Intel(R) 82801GBM SATA AHCI Controller'
      If the controller above is present, the system is an 
      ICH7M system in AHCI mode. Continue with Part 2B below.

    - 'Intel(R) 82801GR/GH SATA AHCI Controller'
      If the controller above is present, the system is an
      ICH7R/DH system in AHCI mode. Continue with Part 2B 
      below.

    - 'Intel(R) 82801FBM SATA AHCI Controller'
      If the controller above is present, the system is an
      ICH6M system in AHCI mode. Continue with Part 2B 
      below.

    - 'Intel(R) 82801FR SATA AHCI Controller'
      If the controller above is present, the system is an 
      ICH6R system in AHCI mode. Continue with Part 2B 
      below.

    - If none of the controllers above are shown, then 
      the system is not in AHCI mode. No other modes are 
      supported by the Intel Matrix Storage Manager 
      software. Continue with step 7 below.

7.  The system does not appear to be running in RAID or 
     AHCI mode. If you feel that the system is running in 
     RAID or AHCI mode and you do not see any of the 
     controllers listed above, contact the system manufacturer 
     or the place of purchase for assistance. You cannot 
     continue with Part 2 below until the system mode is 
     determined.



************************************************************
* Part 2A: System in RAID Mode
************************************************************

The procedure in this section can only be performed on a 
system that is in RAID mode. Do not continue with this 
procedure unless you have completed the steps in Part 1
above to determine this is true for this system. Before 
continuing, be sure to read the warnings below.

WARNINGS:
a. If a RAID 0 volume is deleted, all data on that volume 
will be permanently deleted. Back up all critical data 
before continuing. 

b. If a RAID volume containing operating system files 
is deleted, the operating system will have to be reinstalled.


1.  Ensure you have read and understand the warnings listed
    above.

2.  Reboot the system.

3.  Note whether you see a splash screen titled 'Intel(R)
    Matrix Storage Manager option ROM' during 
    the system startup. If so, continue with step 4 below. 
    If not, skip step 4 and continue with step 5 below.     

4.  Complete this procedure if the Intel Matrix 
    Storage Manager option ROM is installed:

    4a. Enter the Intel Matrix Storage Manager option
         ROM Setup by pressing Ctrl-I when prompted during 
         the system startup.
    4b. In the setup program, select menu option 2 
         to enter 'Delete RAID Volume' menu.
    4c. Select the volume you want to delete using up or down 
         arrow keys.
    4d. Press 'Del' key to delete the selected volume, and 
         press 'Y' to confirm deletion. Repeat this step as 
         necessary to delete all volumes that are present. 
    4e. Exit the setup program.
    4f. Enter the system BIOS Setup (usually done by either 
         pressing a key 'F2' or 'Delete' as soon 
         as the system begins to boot).
    4g. Change the IDE configuration for the Serial ATA
         Controller from 'RAID' to 'IDE'.
    4h. Save changes and exit the system BIOS setup.

5.  Complete this procedure if Intel Matrix Storage Manager
    option ROM is not installed:

    5a. Enter the system BIOS Setup (usually done by either
         pressing a key such as 'F2' or 'Delete' as soon 
         as the system begins to boot).
    5b. Change the IDE configuration for the Serial ATA
         Controller from 'RAID' to 'IDE'.
    5c. Save changes and exit the system BIOS setup.

6.  Reboot the system.



************************************************************
* Part 2B: System in AHCI Mode
************************************************************

The procedure in this section can only be performed on a 
system that is in AHCI mode. Do not continue with this 
procedure unless you have completed the steps in Part 1
above to determine this is true for this system. It is
recommended that you back up all important data 
before continuing. 

1.  Reboot the system.

2.  Enter the system BIOS Setup (usually done by either
    pressing a key such as 'F2' or 'Delete' as soon as 
    the system begins to boot). 

3.  Change the IDE configuration for the Serial ATA
    controller from 'AHCI' to 'IDE'.

4.  Save changes and exit the system BIOS setup.

5.  Reboot the system. The operating system should 
    start as before.


Note: If you experience any difficulties making these 
changes to the system BIOS, please contact the motherboard 
manufacturer or the place of purchase for assistance.
