Entering the ROM Monitor Program
The ROM monitor diagnostics help initialize the processor hardware and boot the main operating
system software. If you set the software configuration register (bits 3, 2, 1, and 0) to zero, you can
start the access server in the standalone ROM monitor. An example of the ROM monitor prompt
follows:
rommon 1 >
To enable the Break key, and to default to booting at the ROM monitor while running the system
software, reset the configuration register to 0x0 by entering configuration mode, and enter the
following configuration command:
config-reg 0x0
The new configuration register value, 0x0, takes effect after the access server is rebooted with the
reload command. If you set the configuration to 0x0, you will have to manually boot the system from
the console each time you reload the access server.
