1. Change History
   
   Version bFW413000 - JS1FW408F.IMG
   - Initial Release.


2. Please refer to the IBM Support Web site at:

   http://www.ibm.com/pc/support/ 

   for the current version of the JS20 Installation and User's Guide, and the Hardware
   Maintenance Manual and Troubleshooting Guide. 


3. Installation, Flash Update and Commit Instructions

   1).  Flashing is performed by a standard Linux Utility. If you have not installed the 
        ppc64 Linux utilities, please install them from the following WEB Link:

        https://techsupport.services.ibm.com/server/Linux_on_pSeries/ServiceAids.html
            
        The "update_flash" utility is used to flash Firmware. 

   2).  Obtain the current Firmware image file from:

        http://www.ibm.com/pc/support   

   3).  Perform Update Firmware using the Linux command:
              
        update_flash -f <filename>

	This will flash the Firmware image to the TEMP side. 

   4).  After the system reboots successfully and once you are satisfied with the
        functionality of the new image, you MUST commit the update using the
        following Linux command:
              
        update_flash -c
            
	This will copy the image from the TEMP to the PERM side 
        --  TEMP - Normal Boot,   PERM - Backup boot bank


4. Reject Image Instruction  
        
   You may reject the Firmware image on the TEMP side by copying the PERM side image
   to the Temp side. You must have booted from the PERM side to perform this function.
   This would be required if you booted to the PERM side for some unexpected reason 
   and you desire to replace the image on the TEMP side. 

   1). To reject the TEMP side image and copy the PERM side to image to the TEMP side,
       issue the following Linux command: 
	
       update_flash -r


5. New BIOS / Firmware version and boot information can be displayed by executing a 
   Linux command

   After performing a flash update of the Firmware,the Firmware (BIOS)version number
   and date are not immediately refreshed for display by the Management Module (MM). 
   The version number of the image you booted (either TEMP or PERM) will be available
   after the MM is restarted. However, Linux commands can also be used to display this
   information prior to restarting the MM.      

   1). To determine whether the system booted from the Temp ("T") or Perm ("P")
       side enter the command: 

       lsprop -R /proc/device-tree/ibm,fw-bank

       This will return: 
       /proc/device-tree/ibm,fw-bank "T"   (if you booted from the TEMP side)
       /proc/device-tree/ibm,fw-bank "P"   (if you booted from the PERM side)

   
   2). To determine the firmware version of the side you booted, enter the
       following command and look for the "ibm,fw-vernum_encoded" property value:
       
       lsprop -R /proc/device-tree/openprom

       As an example for FW version bFW0413000, 
       this will return: name "openprom"
                         ibm,fw-vernum_encoded "bFW0413000" 
                         model  "IBM,bFW0413000"
