      "This MIB is an extension of the ENTITY-MIB
    specified in RFC2737.
    
    This MIB module contains  Cisco-defined  extensions 
    to the  entityPhysicalTable to represent information
    related to entities of class module(entPhysicalClass
    = 'module') which have a Processor.
    
    A processor module is defined as a physical entity
    that has a CPU, RAM and NVRAM  so that
    it can independently
       - load a bootable image
       - save configuration.
    This module is the entry point for external
    applications like SNMP Manager, CLI, FTP etc.
    
    Line card is an interface card         with at least a 
    Processor and RAM. This might be referred to as 
    Service Module in some cisco products.
    
    A configuration register is  a 16 bit 
    software register.
    The configuration register is mainly used to 
    check for instructions on where to find the Cisco 
    Operating System software.
    Some other functions of configuration register are:
     - To select a boot source and default boot filename.
     - To enable or disable the Break function.
     - To control broadcast addresses.
     - To set the console terminal baud rate.
     - To load operating software from Flash memory.
     - To allow us to manually boot the system using the 
       boot command at the bootstrap program prompt.
    
    Booting is the process of initializing the
    hardware and starting the Operating System.";
