If you have no connectivity, you can opt for a serial connection, where cutting and pasting will be your best friend, otherwise try and get IP connectivity going, probably using the default DHCP addresses used in the quickstart. ( from memory)..

You can use tftpdnld from ROMMON.  Set the IP info, specify the filename of the image on the TFTP server and the IP address of the TFTP server.  For example:

rommon 1 > IP_ADDRESS=    <--assign an IP to the router
rommon 2 > IP_SUBNET_MASK=   <--assign the mask
rommon 3 > DEFAULT_GATEWAY=   <--assign a gateway if necessary
rommon 4 > TFTP_SERVER=   <--specify the TFTP server IP
rommon 5 > TFTP_FILE=c2600-is-mz.12.3(8)T.bin     <--specify the image name on the TFTP server
rommon 6 > tftpdnld  <--start the TFTP download
Does you router use a flash card? We simply remove the flash card and connect it to a computer and copy and paste the IOS onto the flash, pop it back in the router and back to normal.
