Specifying Cisco IOS Image Used to Boot the System

Use the following series of commands to specify that a Cisco IOS software image is bootable. (In this example, the file is named new.image.) Note that because the configuration register must be set to 0x2102, the config-registercommand is part of the sequence.

Router# config terminal

Router(config)# no boot system

Router(config)# boot system flash slot0:new.image

Router(config)# config-register 0x102

Crtl-z

Router# copy running-config startup-config

Router# reload

When the system reloads, it will boot the Cisco IOS software image from the Flash memory card or Flash disk in slot 0.

Note In the preceding example, the configuration register value 0x102 instructs the system to boot a default Cisco IOS software image from Flash memory. If a network boot fails, the value 0x2102 instructs the system to ignore a break, and the value 0x0002 instructs the system to look in Flash memory for this default Cisco IOS software image.

Software Commands Associated with Flash Memory

Following are software commands related to the onboard Flash memory on the GRP and the Flash memory cards and Flash disks.

Note If using an ATA Flash disk, replace any commands that include a slot0: or slot1: command argument with a disk0: or disk1: command argument.

Determine which memory media you are accessing using the pwd command as follows:

Router# pwd slot0

Move between Flash memory media using the cd device-namecommand, where device-namecan be slot1:, slot0:, or bootflash:. Examples follow:

Router# cd slot1: Router# pwd slot1

Router# cd slot0: Router# pwd slot0

You can list the directory of Flash memory media using the dir [device-name] command, where device-namecan be slot0:, slot1:, or bootflash:. An example of the dir command follows:

Router# dir
-#-	-length-	-----date/time------	name
1	4601977	May 10 1997 09:42:19	myfile1

6679 May 10 1997 05:43:56 todays–config
