rom monitor help


We have a Cisco 837 router and I deleted IOS due to certain confusion and now it is in ROM Monitor mode. I have done all the set commands with the relevant IP address`s but every time I am getting an error i.e. Invalid or illegal IP address. Any advice ?

Thanks in advance !

It's a while since I tried it but I am sure you can use tftp download. You will of course need a TFTP server on your PC.

try to use Xmodem copy with your console cable. It's slow but work well. Use Windows Hyperterminal.
