What Is Rommon Mode

14

HELP!!!I am in desperate need from someone to help me or perhaps guide me through on this. Recently i tried to upgrade flash in cisco 2691 256d/64f of mine and image i guess got corrupted and i never troubleshoot in this level before, i tried used xmodem to temporary put image in DRAM but with no luck.

Yes, many many ouch! I also had changed the confreg 0x2102 and so on which in rommon you get very limited command but nothing seme to work at the moment. That is a valid directory listing from flash. The image should be okay if it will show you all that.Can you reload the old image and boot normally?One other wild thought, and I can't even remember if a 2691 has this. On my 2800, there is a PCMCIA card that can actually be removed from the router.
