Hi. My router recently will not boot from the flash. I keep getting the rommon prompt. When it tries to boot I get:

I can upgrade the rommon just fine, and i have tried different versions of rommon with no difference.

I have used both SolarWidnows TFTP and tftp32.exe to flash, still no difference.

Any suggestions on something to try? Shouldn't I beable to load a new IOS via rommon? I have also tried xmodem (which took 3 hours) with the same results.

Thank you in advance.

then it does a very fast series of:

and then the cursor starts blinkig at the begining of next line. and the 837 just stays like that.

some other commands i performed:

monitor: command "boot" aborted due to user interrupt
rommon 1 > confreg
