Hi
do find the sample note avl with cisco on upgrading/uploading the microcode in the flash system..
"Cisco 7000 series routers feature downloadable software and microcode for most new images.
Also, microcode images are bundled with the system code, so individual microcode upgrades are no longer necessary.
If the required system software and microcode are not available in your system, contact a customer service representative for upgrade information"
Also refer this link for more info on tht ...
