Disabling the Power Down Feature of the 82566 GbE on EKF CCG-RUMBA:
===================================================================

   To disable the Power Down Feature of the 82566 Gigabit Ethernet
   Controller on the CCG-RUMBA an update of the NVM (*1) image is
   necessary by reprogramming parts of the SPI (*2) flash memory
   on EKF CCG-RUMBA.

   Follow the steps described below for patching the NVM image on
   EKF CCG-RUMBA:
   - Copy all files of the ZIP archive to a bootable DOS formatted
     device (e.g. USB disk or USB stick)
   - Boot the system from this device
   - When the DOS prompt displays, press <566DISPD> <ENTER>
   - Wait for end of programming, view result. If an error occurs
     during programming (which is very unlikely), try batchfile
     566DISPD.BAT once more BEFORE the system is reset
   - When finished successfully restart your system by a power-off-on
     sequence

   WARNING:
   Do not interrupt the programming procedure in order to avoid
   damage of the Flash. Programming takes max. 20 seconds if the
   batch file is loaded from a (USB) floppy disk and about 5 seconds
   when the batch file is loaded from an USB-Stick or a harddisk.

   NOTE:
   The batchfile also performs a check whether the NVM image contains
   a bad MAC-ID, e.g. 888888:888788. If so a warning is issued and
   the batchfile recovers the original MAC-ID.

   (*1) NVM = Non Volatile Memory
   (*2) SPI = Serial Peripheral Interface
