Bit 13 determines the router’s response to a bootload failure. Setting bit 13 causes the router to load operating software from ROM after six unsuccessful attempts to load a boot file. Clearing bit 13 causes the router to continue indefinitely to attempt loading a boot file. By factory default, bit 13 is set to 0.
Bits 5, 11, and 12 of the configuration register determine the baud rate of the console terminal. Table
