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 -loption displays supported DRAM configurations. The following example is a sample of the meminfo -lcommand 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
-------------				-------------				------------
0	MB	0	MB	32	MB	0	MB	32	MB
0	MB	0	MB	64	MB	0	MB	64	MB
0	MB	0	MB	128	MB	0	MB	128	MB
0	MB	0	MB	256	MB	0	MB	256	MB
32	MB	0	MB	0	MB	0	MB	32	MB

128	MB	0	MB	64	MB	0	MB	192	MB
128	MB	0	MB	128	MB	0	MB	256	MB
