6.1
Overview
The MVME2500 uses Das U-Boot, a boot loader software based on the GNU Public License. It 
boots the blade and is the first software to be executed after the system is powered on.
Its main functions are:
Initialize the hardware
Pass boot parameters to the Linux kernel
Start the Linux kernel
Update Linux kernel and U-Boot images
This section describes U-Boot features and procedures that are specific to the MVME2500. For 
general information on U-Boot, see
