This is what it looks like on a real switch: Above you see that it‟s checking the flash drive of the switch. Next step is to load the IOS image that it found on the flash drive.
IOS images are stored on the flash drive in a compress format, it will be uncompressed and copied to the RAM of the switch.
Now IOS is loaded you will see something like this, you see this banner and the IOS version that I‟m running. This is a Cisco 3560 switch.
