Option 2: Boot from Flash Memory

Select option 2. Boot from Flash memory to perform a manual boot from flash

memory. If the boot is unsuccessful, the router returns to manual boot mode. (When

you first receive the router, it defaults to booting from flash during power-up or

automatic reboot.)

Option 3: Boot from Network

Once you have installed router software on a network TFTP server, you can have the

router boot across the LAN. Option 3 requests a manual boot from the network. It

uses the network boot parameters you have defined using Option 5.

If you have not defined network boot parameters, the router attempts to locate a

BOOTP or RARP server on the network.

• BOOTP can be used to supply an IP address, a TFTP server IP address, and

a file name.

• RARP can obtain an IP address, if it knows the MAC address. The router

assumes that the RARP server is also capable of performing the duties of a

TFTP server and so the router requests the file KERNEL.F2K (or the

filename assigned when permanent network boot parameters are set.)

If a BOOTP or RARP server exists and is properly configured with the router’s MAC

address, the router boots from the network.

If the boot from the network is unsuccessful, the router returns to manual boot mode.

Option 4: Boot from Specific File

Select option 4 to temporarily override permanent network boot parameters when you

perform a network boot.

1. After you select option 4, the current default (permanent) parameters are

shown.

2. Set new temporary values for the network boot parameters.

3. Press the return key and the router boots from the network using the

temporary boot parameters.

If the boot is unsuccessful, the router returns to manual boot mode.

Option 5: Configure Boot System

Select option 5 to specify permanent network boot parameters. This menu is

illustrated in Figure 4-2.

Select options 2, 3, and 4 to set the three boot parameters (boot IP address, TFTP

boot server address, and router software file name on the server). To reset any

parameter, press enter following the prompt.
