92
           When targetting the SE7751 board it is possible to build
93
           the system for either RAM bootstrap or ROM bootstrap.
94
           RAM bootstrap generally requires that the board
95
           is equipped with ROMs containing a suitable ROM monitor or
96
           equivalent software that allows GDB to download the eCos
97
           application on to the board. The ROM bootstrap typically
98
           requires that the eCos application be blown into EPROMs or
99
           equivalent technology. ROMRAM bootstrap is similar to ROM
100
           bootstrap, but everything is copied to RAM before execution
101
           starts thus improving performance, but at the cost of an
