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:
File size Checksum File name
2229799 bytes (0x220627) 0x469e CVG224-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
-------------------------------------------------
Current Memory configuration is:
Dimm0: Size = 128 MB : Start Addr = 0x00000000
-----Bank 0 128 MB
-----Bank 1 0 MB
Dimm1: Not Installed
-------------------------------------------------
Main memory size: 128 MB in 64 bit mode.
Available main memory starts at 0xa000e000, size 131016KB
IO (packet) memory size: 0 percent of main memory.
NVRAM size: 88KB
• meminfo [-l]—The meminfo command with the -l option displays supported DRAM
configurations. The following example is a sample of the meminfo -l command output:
rommon 10 > meminfo -l
The following 64 bit memory configs are supported:
-------------------------------------------------
DIMM SOCKET 0 DIMM SOCKET 1 TOTAL MEMORY
Bank 0 Bank1 Bank 0 Bank 1
