Implementing Additional Configuration and Maintenance Tasks
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
Router# config terminal
Router(config)# no boot system
Router(config)# boot system flash slot0:new.image
Router(config)#
Router# copy
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
Router# cd slot1: Router# pwd slot1
Router# cd slot0: Router# pwd slot0
You can list the directory of Flash memory media using the dir
Router# dir |
