System Initialization
Starting a router begins with hardware initialization (a reset or power cycle). By default, the
system searches Compact Flash Slot #3 (cf3) for the boot.ldr file (also known as the bootstrap
file). The boot.ldr file is the image that reads and executes the system initialization commands
configured in the boot option file (BOF). The default value to initially search for the boot.ldr
file on cf3 cannot be modified.
The following is an example of a console display output when the boot.ldr file cannot be
located on cf3.

(memory test messages)
(serial number information)
Searching for boot.ldr on local drives:
No disk in cf3
No disk in cf3
No disk in cf3
Error - file boot.ldr not found on any drive
Please insert CF containing boot.ldr. Rebooting in 5 seconds.
When the bootstrap image is loaded, the BOF is read to obtain the location of the image and
configuration files. The BOF must be located on the same compact flash drive as the boot.ldr
file.
