The trick is to change the configuration register first to 0x3922 or use the
speed command on the line console 0 and set it to 115200. The 2600 and 3600
series routers only support xmodem transfers. Then use the -R option to
write the image just to RAM and not directly to flash first. This way the
image will be downloaded to ram and then bootup immediately which is faster.
You can also use the -y option for ymodem transfer which is also faster.
You will still need to copy the image to flash once you finish booting up
the router but now you can do this using the copy tftp flash command and
copy the image through a lan interface instead.

and not all people have enough time and to wait for an IOS file to load
through a 9600bps connection.
Henry just to let you know this method will take forever to load. I would
recommend any other method if you have it.
