Product Numbers:

MEM2620-32FSBOOT=

This document describes the procedures for replacing the BootROM in a Cisco 2620 or Cisco 2621 router. Cisco 2620 and Cisco 2621 routers can be upgraded to support a maximum of 32MB of Flash memory when using both the Cisco 2600 BootROM version 12.1(3r)T2 (supplied with Cisco p/n MEM2620-32FSBoot=) and Cisco IOS Release 12.1.3T, 12.2, 12.2T, or later Cisco IOS versions.

Note You can upgrade the BootROM to support 32MB Flash in the following routers: Cisco 2620 and Cisco 2621.

Cisco 2620XM and Cisco 2621XM routers already support 32MB Flash; they do not require a BootROM upgrade.
