Chapter 7: Manually Loading System Images

zAllows you to save any configuration changes made before you exit out of the system image.

zNotifies users logged in to the system of the impending switch to the boot ROM image so that they do not lose their connections un- expectedly.

zLogs console output during the Flash load helper operation into a buffer that is preserved through system reloads. You can retrieve the buffer contents from a running image. The output is useful when console access is unavailable or when a failure occurs in the download operation.

Flash load helper can also be used on systems with multiple banks of Flash memory that support Flash memory partitioning. Flash load helper enables you to download a new file into the same partition from which the system is executing an image.

For information about how to partition multiple banks of Flash mem- ory so your system can hold two different images, refer to Partition Flash Memory Using Dual Flash Bank.

zMonitor Flash Load Helper

Download a File Using Flash Load Helper

To download a new file to Flash memory using Flash load helper, check to make sure that your boot ROMs support Flash load helper and then type the following in privileged EXEC mode:

copy tftp flash

This error message appears if you are in a Telnet session and the sys- tem is set for manual booting (the boot bits in the configuration regis- ter are zero):

ERR: Config register boot bits set for manual booting

In case of catastrophic failure in the Flash memory upgrade, this erro message helps to minimize the chance of the system going down to ROM monitor mode and being taken out of the remote Telnet user's control.
