86 When targetting the CQ7708 board it is possible to build
87 the system for either RAM bootstrap or ROM bootstrap.
88 RAM bootstrap generally requires that the board
89 is equipped with ROMs containing a suitable ROM monitor or
90 equivalent software that allows GDB to download the eCos
91 application on to the board. The ROM bootstrap typically
92 requires that the eCos application be blown into EPROMs or
93 equivalent technology."
