For whatever reason, the router cannot find a valid image in flash. When the
router is booting, send a break sequence, which might be hard to figure out
depending on your terminal software. Sometimes it's ALT-B or CTRL-BREAK.
This will drop you into rommon mode. From here you can use xmodem or ymodem
to download an IOS from your terminal software. I have used xmodem-1k in
the past with great success. Unfortunately, on the 3600 there is no option
for tftp from this mode. You'll want to bump up the console port speed to
56k and make the same change in your terminal software. Otherwise it will
take a very long time.
Obviously, for this to work you'll need to have the IOS image on your laptop
or PC. To make this faster, you should load a small image, like 12.0(x) IP
only. Those are relatively small images and won't take too long. Once you
have a valid image you can reboot and then use tftp to load the image you'd
really like to have on there.
HTH,
