Enabling Booting from CompactFlash Memory
Enabling Booting from CompactFlash Memory
To enable booting from CompactFlash memory, set bits 3, 2, 1, and 0 to a value between 2 to 15. To
specify a filename to boot, enter the system software configuration command boot system flash
[device:] [partition:] [filename] in the configuration file.
By specifying the device and partition in the command, you can configure the router to boot from an
external CompactFlash card. If you specify only the filename, the router is configured to boot from
internal CompactFlash memory.
To enter global configuration mode while in the system software image, enter the configure command
at the enable prompt, as in the following example:
Router# configure
Configuring from terminal, memory, or network [terminal]? terminal
Enter configuration commands, one per line.
Edit with DELETE, CTRL/W, and CTRL/U; end with CTRL/Z
boot system flash filename
To disable Break and enable the boot system flash command, enter the config-register command with
a value, as follows:
Router(config)# config-reg 0x102
Router(config)# Ctrl-z
If you set the configuration register value to 0x102, as in this example, you need not enter the
boot system flash command unless more than one image is in CompactFlash memory.
