2621XM router will not boot from IOS image

I've got a 2621XM that has not been used for a while.

Completely stripped of any modules and configuration files, the router will continually cycle the startup process without actually booting from the IOS.

The cycle displays the following :

System Bootstrap, Version 12.2(8r) [cmong 8r], RELEASE SOFTWARE (fc1)

Copyright (c) 2003 by cisco Systems, Inc.

program load complete, entry point: 0x80008000, size: 0x10034ec

What I've tried:

1) Downloading another IOS image (c2600-is-mz.123-20.bin) via Xmodem and running "confreg 0x2102" from the rommon.

All that did is change the last message to "program load complete, entry point: 0x80008000, size: 0x10fa95c"

2) Running the command "boot flash:c2600-is-mz.123-20.bin"

If I enable the diagnostics via rommon, the cycle expands to:

System Bootstrap, Version 12.2(8r) [cmong 8r], RELEASE SOFTWARE (fc1)

Copyright (c) 2003 by cisco Systems, Inc.

program load complete, entry point: 0x80008000, size: 0x10fa95c

Testing lower main memory - data equals address

Testing lower main memory - checkerboard

Testing lower main memory - inverse checkerboard

Clearing lower 4K memory for cache initialization

Clearing bss

Reading monitor variables from NVRAM

Enabling interrupts

Enabling instruction cache

Reading cookie

Initializing main memory

Sizing NVRAM

Initializing PCI subsystem

Exiting init

C2600 platform with 131072 Kbytes of main memory

If it wasn't for the lack of error messages, I would assume it was a hardware issue.

If the image was corrupted, I would expect a message indicating that the image couldn't be read.

Any suggestions are welcome.

2621XM router will not boot from IOS image

In rommon if you do "show flash:" do you see the IOS that you want to boot? 

Also can you post the output of the "set" command?
