I recently upgraded the IOS platform of C871 we use in our network. I forgot to issue the router config command "boot system flash: 'name of file' . When i reloaded the router, it keeps booting to romon.
I've tried using "confreg 0x2102" command in the the Romon environment but to no avail. I've done reset and i am even thinking of booting the router from a tftp server but i dont know how and if it will be possible.
Can someone help me with idea on how to solve this?
Here are some guidelines if you need to boot from USB:
1. Maximum size of USB is 2Gb;
2. Format the USB first (command: format usbflash0:) before copying files into it; and
3. Set boot statement (boot system usbflash0:).
Hope this helps. Please rate when helpful or applicable.
