Taking the original (known good) MD5 from cisco.com and then matching it up by using Verify on the router ensures you are not about to buy yourself a long drive out to the site! :D You can, but that doesnt help you to determine if the file was corrupted in-transit.

"Another thing to look for is that when you use tftp (Trivial File Transfer Protocol) to upgrade your image from a tftp server, you should look for two "OK"s. The 1st OK will indicate that the file transfer completed successfully and the 2nd OK will indicate that the checksum of the file validated correctly." nice.
