eng_ahmedas

Dear friends
I wish you are all in very good health. i have a question about the router boot sequence and i wish you could help me.

In the step of finding and loading IOS image for cisco router , it checks first for boot system comands , then if not found, it load first image in flash , if no valid IOS image in flash , it try to load IOS image from TFTP server, if not found , it load limited IOS from rom..... then it try to find and load configuration file...

My question is , i know that boot system commands saved in configuration file , if that true , how the router check for the boot system commands in the step of finding and loading IOS image before it load the configuration file in the next step ?????

I wish my question is clear
Thanks in advance
Bye
