Replacing the Boot ROM
Cisco 261x, Cisco 262x, Cisco 265x, and Cisco 26xxXM Routers
Note
32 MB Flash memory support is limited to the Cisco 2620(XM), Cisco 2621(XM), Cisco 2650(XM)
and Cisco 2651(XM). The Cisco 261x (2610, 2611, 2612 and 2613) cannot be upgraded to support
32 MB of Flash regardless of the boot ROM version.
To upgrade the router ROM software to a new ROM monitor version, you must replace the existing
ROM. Follow this procedure to replace the ROM:
Caution
Correct placement of the ROM is crucial. If improperly positioned, the new component could be
damaged when the router is powered on. Read all instructions before proceeding. To prevent damage
to the ROM from ESD (when handling the router and its components), follow the ESD procedures
described in your hardware guide and see the Regulatory Compliance and Safety Information
document. Be careful not to damage or scratch the printed circuit card under the ROM.
Step 1
Locate the ROM on the system card (motherboard) layout as shown in
Figure B-13
and
