# that resides strictly in RAM and is used for two main purposes:
# 1. To test new monitor features prior to burning the boot flash.
# 2. To be downloaded into the RAM space of a board that has no programmed
#    boot flash.  This provides a running monitor that can then accept
#    an incoming bootflash image using 'newmon'.
