Exiting the ROM Monitor
You must set the configuration register to a value from 0x2 to 0xF for the router 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 router 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 router will boot the Cisco IOS image in flash memory. The configuration register will change to
0x2101 the next time the router is reset or power cycled.
