/*
DESCRIPTION
This is the WRS-supplied configuration module for the VxWorks boot ROM.
It is a stripped-down version of usrConfig.c, having no VxWorks shell or
debugging facilities.  Its primary function is to load an object module
over the network with either RSH or FTP.  Additionally, a simple set of
single letter commands is provided for displaying and modifying memory
contents.  Use this module as a starting point for placing applications 
in ROM.
