Appendix C Using the ROM Monitor

Entering the ROM Monitor Mode

•You can override the default boothelper image setting by setting the BOOTLDR Monitor environment variable to point to another image. Any system image can be used for this purpose.

•Options to the boot command are -x, load image but do not execute, and -v, verbose.

•Use the Cisco IOS commands show version and show hardware to display the source of the currently running image.

–dir device:[partition:]—List the files on the named device. For example:

rommon 8 > dir flash: /dir slot0:
