Manually Load a System Image from ROM Monitor

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.

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. boot flash [ filename]
