If the router has a slot for a PCMCIA flash card you could copy the IOS image to the flash card installed in a working router, then move the flash card to the router in ROMMON and boot. You'll need to use the "dev" command to find the device name, then the "boot slot0:filename" command to bring the router up.

If you've not the option for using PCMCIA then you'll have to resort to the Xmodem Console Download Procedure (http://www.cisco.com/en/US/partner/products/hw/routers/ps259/products_tech_note09186a008015bfac.shtml)
