1-10 Cisco 4000 Series Installation Guide

Memory Systems

when Flash memory does not contain a valid system image. In the Cisco 4500-M and

4700-M, the ROM monitor allows you to boot a system image from Flash memory if a

boot helper image is not present in boot Flash memory.

The differences between the memory systems in the Cisco 4000 series allows enhanced

software upgradability in the Cisco 4500-M and Cisco 4700-M.

Note See the appendixes “Cisco 4000 Series Virtual Configuration Register,”

“Cisco 4000-M ROM Monitor,” and “Cisco 4500-M and Cisco 4700-M ROM Monitor”

for more information on the ROM Monitor.
