•
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 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.
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:
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.
0x2101 the next time that you reset or power cycle the voice gateway.
