• frame—Displays an individual stack frame.
• sysret—Displays return information from the last booted system image. This information includes
the reason for terminating the image, a stack dump of up to eight frames, and, if an exception is
involved, the address where the exception occurred; for example:
rommon 8> sysret
System Return Info:
count: 19, reason: user break

• meminfo—Displays size in bytes, starting address, available range of main memory, the starting
point and size of packet memory, and size of NVRAM; for example:
rommon 9> meminfo
Main memory size: 128 MB.
Available main memory starts at 0x10000, size 40896KB
IO (packet) memory size: 5 percent of main memory.
Exiting the ROM Monitor Mode
You must set the configuration register to a value from 0x2 to 0xF for the voice gateway to boot a
Cisco IOS image from flash memory upon startup or reloading.
The following example shows how to reset the configuration register and cause the voice gateway to boot
a Cisco IOS image stored in flash memory:
rommon 1 > confreg 0x2101
You must reset or power cycle for a new configuration to take effect:
rommon 2 > boot
The voice gateway boots the Cisco IOS image in flash memory. The configuration register changes to
0x2101 the next time that you reset or power cycle the voice gateway.
