Overview of Cisco Device Startup

Overview of Cisco Device Startup
1.This event is a series of hardware tests to verify that all components of the router are functional. POST executes from microcode resident in the system ROM.

2.Bootstrap code is used to perform subsequent events like finding the IOS software, loading it, and then running it.

3. The bootstrap code determines where the IOS software to be run is located. The configuration register, configuration file, or Flash memory are the normal places to house the IOS image.

4. Once the bootstrap code has found the proper image, it then loads that image into RAM and starts the IOS running

5. The default is to look in NVRAM for a valid configuration.
6. The desired configuration for the router is loaded and executed.
