Chapter 1 CompactFlash Disk, Flash Disk, and Flash Memory Card Information

Working with a CompactFlash Disk, Flash Disk, or Flash Memory Card

Use the following procedure to enable booting the file myfile from a Flash memory card:

Step 1 Enter configuration mode and specify an image filename in the PC card slot from which to boot by using

the configure terminal command, as follows:

System# configure terminal

Enter configuration commands, one per line. End with CTRL-Z.

System(config)# boot system flash disk0:myfile

Note Specify disk2: for a CompactFlash Disk on the NPE-G1 or NPE-G2.

Step 2 Enable the boot system flash disk0:myfile command using the config-register command with the

hexadecimal value shown in the following example:

System(config)# config-reg 0x2102

This command, with the hexadecimal value 0x2102, results in the following:

• Enables the system to boot the default boot ROM software if the Flash Disk-based image fails to

boot—hexadecimal value 0x2000

• Disables Break—hexadecimal value 0x0100

• Enables the image myfile as the default boot image—hexadecimal value 0x0002

Step 3 Press Ctrl-Z to exit configuration mode:

System(config)#

Crtl-Z

System#

Step 4 Save the new configuration to NVRAM by using the copy system:running-config

nvram:startup-config command as follows:

System# copy system:running-config nvram:startup-config

Making a CompactFlash Disk or Flash Disk-Based Software Image the

Bootable Software Image

After you copy a software image to the Flash Disk, use the following series of commands to make the

image bootable (the file named new.image in this example). The software image in this example is

located on the Flash Disk in PC card slot 0. Note that the config-register command is also a part of this

command sequence because you must set the configuration register to 0x2102 to enable loading an image

from the Flash Disk.

System# config terminal

System(config)# no boot system

System(config)# boot system flash disk0:new.image

System(config)# config-register 0x2102

Ctrl-Z

System# copy system:running-config nvram:startup-config

System# reload

When the system reloads, it boots the image new.image from the Flash Disk in slot 0.
