Enabling Booting from Flash Memory

To enable booting from flash 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 the
PCMCIA cards. If you specify only the filename, the router is configured to boot from flash memory.
To enter 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:
config-reg 0x102
Ctrl-z
If you set the configuration register value to 0x102, as in this example, you do not need to enter the boot
system flash command unless there is more than one image in flash memory.
