Using a PC with a CompactFlash Card Reader to Copy the System Image into Flash Memory
Because the system image is stored on an external CompactFlash memory card, you can use a PC with
a compact flash card reader to format the card and copy a new system image file onto the card. However,
this upgrade method is not commonly used.
For more information about using flash memory cards, see Using CompactFlash Memory Cards .
Prerequisites
•
Download the new Cisco IOS Software image to the PC. See the “Where Do I Download the System

• Locate the compact flash memory card slot on the router chassis. For help with locating the slot and
