hi Francis:
i did the exact same thing on my lab router, try the following, download a tftp server from solar winds configure it on a laptop or PC with a serial connection and use the console cable provided by cisco. you must get the xmodem util ready (hyper terminal) make sure all the defaults are set:
make sure its connected to COM1
make sure your port settings are set as follows:
bits: 9600
databits: 8
oarity: none
stop bits: 1
flow control: none
click OK
go up to transfer and select send file
select the protocol as Xmodem and browes for the IOS file, DO NOT click on send as of yet, go back to the solar winds tftp server and make sure its running:
open solar wind tftp server> go to file and click on configure, under the general tab click on Start and verify the tftp server service says Started, go back to hyper terminal and click on Send. this should work to get the file uploaded to the device, once you do that make sure you set the config register and use the boot system command to boot off of the new IOS image. Hopefully you will have a backup of your config which you can copy back into global config.
let me know how it goes.

This shows you how to transfer using tftp which is quicker.
