looks like the copy failed for some reason. maybe a corrupt source image. or
async errors.
Since X-modem is so slow, consider putting on a small IP only image, and
then upgrade later using tftp .

Subject: xmodem upgrade problem.
Hi all,
I am trying to upgrade 2621 IOS to (12.2-15(T8). I replaced 8 MB flash to 16
