This error message occurs if either the boot image, or the main Cisco IOS Software image, is incompatible with the Network Processing Engine (NPE) or Network Services Engine (NSE) installed on the router. Depending on which image is incompatible, the router can boot to the ROM Monitor (ROMmon) mode, boot mode, or the main Cisco IOS Software mode.
To eliminate the error message, the software must be upgraded to a compatible version. To determine which software requires an upgrade, perform these steps:
Identify the NPE or NSE installed. If the router is in boot mode or full Cisco IOS Software mode, issue the show version command, as shown:

Determine the images that require an upgrade by issuing the dir [filesystem:] command.
To check the boot image, issue the dir bootflash: command. The command depends on where the Cisco IOS Software image resides. If the image is on a Flash card, issue the dir slot0: command or the dir slot1: command. If the image is on an Advanced Technology Attachment (ATA) Flash disk, issue the dir disk0: command or the dir disk1: command.
Once the incompatible image has been identified, upgrade the image to a compatible version. As long as an interface is available to connect to a TFTP server, this is done from boot mode or Cisco IOS Software mode.
If the router has booted to ROMmon mode, and a valid boot image or Cisco IOS Software image is present, boot directly to the valid image from ROMmon mode by issuing the bootflash-fs: [filename] command.
For example, if a boot image named c7200-boot-mz.120-15.S.bin is on the bootflash, the command would be as shown:
If no valid image is present on either the bootflash, or on a Flash card or Flash disk, the system will not be recoverable from ROMmon mode. If another 7200 series router is available, an image can be copied to the Flash card using the other router. Otherwise, a Flash card or I/O controller with a compatible image already installed must be obtained to recover the router.
If the error messages started after upgrading the NPE or NSE, and the old NPE or NSE is still available, install the old NPE or NSE temporarily. This boots the router and upgrades the software. Reinstall the new NPE or NSE after the compatible software is on the Flash device.
