Monitor Flash Load Helper
To view the system console output generated during the Flash load
helper operation, use the image booted up after the Flash memory up-
grade. Type this command in privileged EXEC mode:
show flh-log
If you are a remote Telnet user performing the Flash upgrade without
a console connection, this task allows you to retrieve console output
when your Telnet connection terminates due to the switch to the ROM
image. The output indicates events occurring during the download and
is particularly useful if the download fails.
Manually Load a
System Image
from ROM
Monitor
If your router does not find a valid system image, or if its configuration
file is corrupted at startup, and if the configuration register is set to
enter ROM monitor mode, the system enters ROM monitor mode.
From this mode, you can manually load a system image from Flash
memory, from a network server file, or from ROM.
You can also enter ROM monitor mode by restarting the router and
then pressing <Break> during the first 60 seconds of startup.
Manually Boot from Flash
To manually boot from Flash memory:
1. Restart the router
reload
2. Press <Break> during the first 60 seconds of system startup.
3. Manually boot the router from Flash.
