Using Flash Memory Cards in the RP

Booting from Flash Memory

To enable booting from Flash memory, set the boot field in the software configuration register (bits 3 through 0) to a value between 2 and 15. These values are used with the boot system flash device:filename configuration command, where device is bootflash:, slot0:, or slot1:, and filename is the name of the file from which you want to boot the system.

To enter global configuration mode while the system is running and specify a Flash filename from which to boot the system, enter the configure terminal command at the privileged EXEC mode prompt on the system console, as follows:

Router# configure terminal

Enter configuration commands, one per line. End with CNTL/Z.

Router(config)# boot system flash device:filename

To disable the Break function and enable the boot system flash device:filename command, enter the config-registercommand at the global configuration mode prompt with the configuration register value, as shown below:

Router(config)# config-reg 0x0102

Ctrl-Z

Router#

Copying Files

Copy a new Cisco IOS software image to Flash memory when a new image becomes available or when you want to back up the image. This section explains how to copy any type of file to the Flash memory SIMM on the RP or to a PCMCIA Flash memory card inserted in either slot 0 or slot 1.

Caution You cannot copy a new Cisco IOS software image into the onboard Flash memory SIMM (also referred to as bootflash) while the system is running from onboard Flash memory.

To avoid losing valid Cisco IOS images, upgrade your Cisco IOS software images in Flash memory one at a time. Upgrade your PCMCIA-based Flash memory separately from the onboard Flash SIMM (bootflash) on the RP.
