3.1 The package.
----------------

The driver package is a compressed tar file.  

To extract the compressed file in the tar file, 
first, uncompress the file:
	"> gunzip <driver_package.tgz>"
then, un-tar the files: 
	"> tar -xvf <driver_package.tar>"
	
The package should contain the following files:
 - dkms rpm (dkms<version>.rpm)
 - driver rpm (mptlinux<version>.rpm)
 - release notes (*.txt)
 - source code (megaraid<version>src.tgz)
 - driver update disk (DUD) image for the different OSes (*.img)

Preparation of the DUD image.  Transfer the image to the floppy:
	Use "> dd if=<image_file_name> of=/dev/fd0"

On most systems, the floppy drive is designated by the /dev/fd0 special file.
It is recommended that the the dd command is executed before the floppy 
is mounted.


3.2 Installing the OS on a SAS controller.
------------------------------------------

-- Installing the driver on a Red Hat Enterprise Linux system  --

Perform the following steps to install RHEL (version 4)
using the DUD:

1  Boot normally to the RHEL installation media.
2  At the command prompt, type:
		> Linux expert dd
3  When the install prompts for a driver diskette, insert the driver update 
   disk (DUD) prepared earlier and press <Enter>.
4  Complete the installation as directed by the installation program.


3.3 Adding/Updating the SAS Driver to an Existing Linux system
--------------------------------------------------------------

1  Install the DKMS rpm package if needed. Use this command 
      "> rpm -ivh <dkms rpm package name>"
   
   NOTE: Use rpm -Uvh <package name> when updating an existing package.
   
2  Install the Driver package. Use this command 
      "> rpm -ivh <driver rpm package name>"

3  Verify the driver has been loaded with this system command:
      "> lsmod mptsas"

   The version shown in the output should match in both cases and 
   with the version of the package.
