I have a Cisco 871W ISR and I purchased 32meg of flash to replace the standard 4meg chip that came with my router. The router has 20meg onboard flash anyway so I knew that removing the additional 4meg chip would effectively cause the router to boot into ROMmon mode (which it did) My problem is this.
I seem to be unable to boot into router boot mode "Router (boot)" after changing the conf register to 0x2101
The router continually boots with the following message regardless how I set the conf register
System Bootstrap, Version 12.3(8r)YI4, RELEASE SOFTWARE

as you can see there is no IOS image or cfg file
If I go through the motion of setting an ip address on the machine using the IP_ADDRESS command it accepts it but the TFTP transfer times out.
Do I need to set the ip address on one of the switchport interfaces like I would expect to do in router boot mode, the 871 has a 4 port switch built into it and Im not exactly sure what ethernet port it would use (suffice to say I have tried them all)
any help would be much appreciated, I'm sure Im missing out something very simple
