Question 3

in what sequence does bootstrap code work to locate cisco ios software?

Answer 3

The bootstrap code checks the boot field of the configuration register. The boot field tells the router how to boot up.

The bootstrap code executes the specifications of the configuration register boot field

If the router searches for and finds valid Cisco IOS images in flash memory, it loads the first valid image and runs it.

If it does not find a valid Cisco IOS image in flash memory, the router attempts to boot from a network TFTP server using the boot field value as part of the Cisco IOS image filename.

After six unsuccessful attempts at locating a TFTP server, the router loads the ROM monitor.
