Appendix C Using the ROM Monitor
Entering the ROM Monitor Mode
enable “ignore system config info”? y/n [n]:
change console baud rate? y/n [n]: y
enter rate: 0 = 9600, 1 = 4800, 2 = 1200, 3 = 2400
4 = 19200, 5 = 38400, 6 = 57600, 7 = 115200 [0]: 0
change the boot characteristics? y/n [n]: y
enter to boot:
0 = ROM Monitor
1 = the boot helper image
2-15 = boot system
[0]: 0
Configuration Summary
enabled are:
diagnostic mode
break/abort has effect
console baud: 9600
boot: the ROM Monitor
do you wish to change the configuration? y/n [n]:
You must reset or power cycle for new config to take effect
Using the show rom-monitor command
The show rom-monitor command displays the current version of the read only ROM monitor, and if
present displays the upgrade version of the ROM monitor. The upgrade version is selected when the
system is rebooted. This command runs in the Cisco IOS exec mode.
You get the following output, when the read only ROM monitor is present:
Router# show rom-monitor
ReadOnly ROMMON version:
System Bootstrap, Version 12.2(4r)XT2, RELEASE SOFTWARE (fc1)
TAC Support: http://www.cisco.com/tac

No upgrade ROMMON programmed or not yet run
Currently running ROMMON from ReadOnly region
ROMMON from ReadOnly region is selected for next boot

Following is an exmaple of an output when both the read only and the upgrade versions of the ROM
moinitor are present:
Router# show rom-monitor
ReadOnly ROMMON version:
System Bootstrap, Version 12.2(4r)XT4, RELEASE SOFTWARE (fc1)

Upgrade ROMMON version:
System Bootstrap, Version 12.2(8r)T1, RELEASE SOFTWARE (fc1)
TAC Support: http://www.cisco.com/tac
Copyright (c) 2002 by cisco Systems, Inc.
Currently running ROMMON from Upgrade region
ROMMON from Upgrade region is selected for next boot

Note You can get the same information if you enter the showmon command in the ROMMON command
mode.
