Just to rule out the "smack yourself on the head if you realise you've
done this" reason - don't suppose the image has been ftp'd from one box to
another somewhere along the line? And transferred as ascii in the
process?
Speaking from experience (yes, I smacked myself on the head when I
realised what I'd done) - that can give those symptoms.

Subject: Checksum failure [7:45856]
Is this part of a business decision process?:
Looking for some help. I'm trying to download (tftp) a new ios image on
my
2503 and after repeated attempts, I continually get a checksum error after
each download. I've changed the config-register to 0x2101 so that the
flash
will switch to Read/Write prior to downloading. I've tried 3 separate
ios
images from cisco and here's what I get after each download:
t(boot)#copy tftp flash
System flash directory:
File Length Name/status
