Router startup issues

I recently received an 1811  router. It appears to have some corruption. On bootup I get the following:

It continues to restart. I have tried to break into ROMMON, but have not had success. What are my options? How can I load ROMMON utility so that I can rebuild this system?

You're certainly in a bit of a bind. Recovery from this situation is possible, but usually requires a working IOS. I would take the CF card out of the system, connect it to a PC, reformat it with FAT32 and put a fresh IOS on it. Once this is done, you can place the CF card back in the unit and see if it will start. If it does, you can reset it to factory defaults by pressing control-break when IOS begins to decompress.
