Configuring Autoboot to Boot from the Network

To configure autoboot to boot from the network, you must have a usable network interface correctly
configured. This procedure assumes your interface is configured and that a default gateway is set if the
TFTP server is not local.
Follow these steps for configuring autoboot to boot from the network:
Step 1 Specify the Cisco IOS image using the boot system command.
Specify the boot loader (optional).
Step 2
Ensure your configuration register is set to autoboot (0x2102).
Step 3
See the following example:

Configuring Autoboot to Boot from a Local Device

The procedure for booting from a local device is similar to booting from the network. However, if you
are booting from a local device, specifying the bootloader image is not necessary.
See the following example:

Using the Bootldr Command

Use the bootldr command to specify an image to boot the system in the case of a system crash. You can
use the bootldr command in Cisco IOS or in ROMmon mode.
You can use the bootldr command in Cisco IOS:

If Cisco IOS fails to boot to the command prompt after a ROMmon upgrade, the ROMmon will
reverts to the "golden" ROM—ROM 0.
If Cisco IOS fails after a ROMmon is newly upgraded, the new ROMmon is marked as bad and may
not be selected for use again. Start the upgrade procedure again from the beginning.
