Appendix C Using the ROM Monitor
Entering the ROM Monitor Mode
• If a minus option is followed by a colon (for example, [-s:]) you must provide an argument for the
option.
• A term in italics means that you must fill in the appropriate information. In the following example,
you replace the term in italics with the interface type you are using:
command type interface
Command Descriptions
This section lists some useful ROM monitor commands. Refer to the Cisco IOS configuration guides and
command references for more information on ROM monitor commands.
• boot or b—Boot an image.
–
boots the first image in Flash memory.
–
flash:[name] boots the Cisco IOS software from the Flash memory.
–
filename tftpserver boots from the specified file over the network from the specified TFTP
server. For example:
boot c2600-i-mz 172.15.19.11
–
filename boots from the boothelper image because it does not recognize the device ID. This
form of the command is used to netboot the image named filename.
• The Cisco 2600 series router does not have a dedicated boothelper image ([rx]boot) as used by
some other Cisco routers. With the Cisco 2600 series router, the first image in Flash memory is
invoked as the default boothelper image anytime the ROM monitor does not recognize the
device ID in the boot command.
• 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:
File size Checksum File name
2229799 bytes (0x220627) 0x469e C2600-j-m2.113-4T
–
help—Display a summary of ROM monitor commands (equivalent to ?).
–
meminfo—Display size in bytes, starting address, available range of main memory, the starting
point and size of packet memory, and size of nonvolatile memory (NVRAM). The following
example shows the meminfo command:
rommon 9 > meminfo
Main memory size: 32 MB.
Available main memory starts at 0xa000e000, size 32704KB
IO (packet) memory size: 25 percent of main memory.
NVRAM size: 32KB
• meminfo [-l]—The meminfo command with the -l option displays supported DRAM
configurations. The following example shows an example of the meminfo -l command:
rommon 10 > meminfo -l
