                              ABOUT THIS RELEASE
=============================================================================
The Hot Swap Controller firmware must be current before running this update.
See the "Important Note" under the Important Installation Notes area below. 


=============================================================================
			SYSTEM HARDWARE REQUIREMENTS/REVISIONS
=============================================================================
Server Board with PC87431M mini-Baseboard Managment Controler (mBMC) from 
National Semiconductor

=============================================================================
		       SYSTEM SOFTWARE REQUIREMENTS/REVISIONS
=============================================================================
- PC87431M mini-Baseboard Managment Controler (mBMC) from National 
  Semiconductor: Firmware Revision 2.40
 
- Latest HSC (SCSI or SATA) backplane firmware.

- Latest FRU/SDR package.

=============================================================================
                         IMPORTANT INSTALLATION NOTES
=============================================================================
This package does not support mBMC updates while the Intel(R) Management 
Module Professional or Advnaced Editions are installed.

- The following files are necessary to update the firmware:

  run.bat	- Batch file used to update the firmware
  m431_240.hex
  mfwu_240.hex	- mBMC 2.40 firmware hex files for the platform
  FWPIAUpd.exe	- DOS utility rev 2.0.1 PR2 which programs the firmware hex
		  file into the flash device.
		  Prior versions of this utility will not work with this FW

Executing the fwpiaupd utility with your own command switches is unsupported 
and may leave your baseboard in a non-operational state! Please use the
provided batch file to update the firmware.

IMPORTANT NOTE:
FAILURE TO FIRST UPDATE THE HOT SWAP CONTROLLER (HSC) ON THE HOT SWAP BACKPLANE 
(HSBP), EITHER SCSI or SATA, MAY RESULT IN A mBMC UPDATE FAILURE OR A BOARD
FAILURE.  ENSURE THAT THE HSC CONTAINS THE REQUIRED FIRMWARE REVISION LISTED
BELOW BEFORE PROCEEDING WITH THE mBMC UPDATE. 

Required HSBP backplane firmware operational code revisions:
SC1400/SC2400
 SATA - 1.08 or higher
 SCSI - 1.06 or higher

SC5300/SC5275E
 6 Drive SATA - 1.08 or higher
 4 Drive SCSI - 1.12 or higher
 6 Drive SCSI - 1.12 or higher

The following command can be used to check for the current version of HSC 
firmware.   "fwpiaupd -i -dirhsc".  Both the Op Code and Boot Block code 
versions will be displayed.  It is the Op Code that is shown above for 
version comparison.    

=============================================================================
                         INSTALLATION PROCEDURE
=============================================================================

- Validate that the server board is a mBMC based system without an Intel(R) 
  Management Module installed. This package does not support mBMC updates
  while the Intel Management Module is installed. Removal of the module is 
  required before proceeding with the mBMC update.
- Validate that the HSC fimrware is either at or higher in the revisions 
  listed above.
- Execute the run.bat file to begin the firmware update process 
- Cycle AC power after the update
- Proceed to install the latest FRU/SDR package.
- Reinstall Intel Management Module if previously installed.
