Chapter 4 System Startup and Basic System Configuration

Using RP Flash Memory Cards

Booting a New Cisco IOS Software Image from a Flash Memory Card

Use the following procedure to boot a new image from a flash memory card in slot 0 or slot 1 (this example uses slot 0).

Step 1 Insert the flash memory card with the new image in slot 0.

Step 2 Enter the following commands to designate the file named image.new as the new default system image for boot purposes:

Milo# configure terminal

Milo(config)# no boot system

Milo(config)# boot system flash slot0:image.new

Ctrl-Z

Milo# copy running-config startup-config

Milo# reload

When the system reloads, it boots the image.new file from the memory card in slot 0.

Recovering from Locked Blocks in Flash Memory Cards

When power is lost or the card is removed from its slot during a write or erase operation, a locked block in flash memory cards occurs.

When a block of flash memory is locked, you cannot write to it or erase it. The only way to recover from locked blocks is to reformat the flash memory card using the format command (see the “Formatting a New Flash Memory Card” section on page 4-47).

Caution Formatting a flash memory card erases all existing data on the card.
