I have a cisco switch with a bad IOS image, it would only boot to rommon.  I formatted the flash and tried using xmodem to copy the new image to flash.  After a couple failures, I realized that the ONLY images that Cisco offers for this device only are TOO BIG for the flash for some reason?

Is there a way to boot the image from a tftp server while in Rommon mode? I have typed in the following:

set IP_ADDRESS 172.16.2.251
set IP_SUBNET_MASK 255.255.255.0
set DEFAULT_GATEWAY 172.16.2.254
set TFTP_FILE c2900xl-c3h2s-mz.120-5.WC17.bin
set TFTP_SERVER 172.16.2.1

I then type boot and it always says boot process failed.

Is it possible to boot the image from Rommon via TFTP, if so what am I doing wrong?

May want to see if the flash is holding any of the SDM components and remove them to make room...

The size of the 12.x images is larger than the flash itself.  After searching around on Cisco's website I eventually found the orginal code that was on the switch (11.x) and it fits on the flash, so I was able to xmodem it to flash.
