2.0  Installation and setup instructions
________________________________________

  Use the following set of instructions to install the supported network 
  operating systems.

  2.1 Working with driver image files to create driver installation media
  -----------------------------------------------------------------------

  These driver images can be used to create a USB key, CD, DVD, or floppy disk 
  containing the driver formatted for use during the installation of the 
  operating system.
  
  1) Copy the .zip file to a temporary directory and extract it.
  
  2) Using the list of supported kernels at the top of this readme, determine 
     which set of .img files you will need for your installation.  Use these 
     files wherever 'the .img file' is referenced in this readme.
  
  3) Using the .img file from your set, create a driver update disk on a USB 
     key, CD, DVD, floppy or other media using the instructions below for your 
     media type.
  
     USB Key:
     --------
     There are two different partitioning methods for USB keys.  One of the 
     methods below will work and the other will not, depending on which way 
     your key is partitioned.  The easiest way to discover which is correct 
     for your key is to try the Quick Copy Method first.  If this method is 
     not correct you will receive a message stating that no driver could be 
     found on your media when you try to load the driver in step 3 below.  If 
     that occurs, you can use the Extraction Method and reinsert the key.  Use 
     the Back button on the installation screens to re-detect the key.  You 
     should not need to reboot or start the installation over.
     
     Quick Copy Method:  Copy the .img file to the root directory of the USB 
     key.  You do not need to remove other files from the key unless there is 
     less space than necessary for the two files.
     
     Extraction Method:  Use an img-to-media application (such as dd, rawrite,
     or emt4win, or ardi4usb) to extract the image to the key.  This method 
     will overwrite all data on the key, so you will need to remove all other 
     files before extracting to the key.  Follow the instructions that came 
     with your img-to-media application to correctly extract to your key.  
  
     All other media:
     ----------------
     Use an img-to-media application (such as dd, rawrite, emt4win, or 
     ardi4usb) to extract the image to the media.  This method will overwrite 
     all data on the media.  If you are using rewritable media, you will need 
     to remove all other files before performing the extraction.  Follow the 
     instructions that came with your img-to-media application to correctly 
     extract to your media.

  2.2 Network operating system installation instructions
  ------------------------------------------------------

  Follow these instructions to add the ServeRAID C100 for System x driver 
  during the installation of RHEL 6.
