You can also issue a show version command to determine if your system has a 16MB boot flash SIMM. An example is shown below:

A copy error results if the image size is too large for the boot flash SIMM.

Workaround/Solution

You can use one of the following options to accommodate
the larger image:

Option 1: If you already have a Flash PC card, download the system image to the Flash PC card by following the steps below:

1. Prior to downloading these larger images, be sure to have a 20Mb PCMCIA module installed in the RP that can accommodate the images.

   Note: If you have a Smart Modular, Sharp, or Intel 2+ Flash PC card that was formatted using a Cisco IOS software release other than 12.0(4a)W5(11a), reformat it with release 12.0(4a)W5(11a) prior to downloading the image. (You might need to boot the image from a TFTP server to format the PC Flash card.) Do not erase the system image on the boot Flash SIMM. If the procedure fails, you will need it to recover.

2. After downloading the image, enter the config-register 0x2102 global configuration command to change the configuration register to boot from the Flash PC card, instead of the system-code SIMM (default).

   Note: If you have a redundant route processor configuration, you need ROMMON image 12.0(4.6), W5(13) or later.

3. Enter the boot system slot0:filename global configuration command to specify the system image to boot on the Flash PC card.
4. Enter the copy system:running-config nvram:startup-config privileged EXEC command to save the configuration changes to NVRAM.

Option 2: Download the system image to a TFTP server and boot the system image from the TFTP server. Enter the boot system tftp filename ip-address global configuration command to boot the system image from the TFTP server, instead of the system-code SIMM (default).

Note: You can boot only the primary route processor from a TFTP server, not the secondary.
