"Fixing bugs in the sample code is an exercise left to the reader."

:-D

Seriously though, thanks for testing the code and reporting what you've
found. I'll be sure to update the manual as soon as I can.

It's probably good. And since you've tested it, I believe you. The next
approach I found was to take advantage of address wraparound inherent in the
W5100's address space. This technique is documented in a thread somewhere in
this newsgroup.

Finally, I also advise looking at Oliver Schmidt's driver for the W5100 (if
you haven't yet). He has some more technical documentation that isn't in the
manual.
