• 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:

Exiting the ROM Monitor
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 new config to take effect:
rommon 2 > boot
The voice gateway will boot the Cisco IOS image in flash memory. The configuration register will
change to 0x2101 the next time the voice gateway is reset or power cycled.
