Looking at http://ipxe.org/err/3d1260, it seems like that is an error
code for an illegal TFTP operation. My guess is that the backslashes in
your TFTP URL are causing the problem. Try to replace them with either
normal slash (/), or use the escape code for backslash (%5C). Your URL
should end up looking something like this:

tftp://${next-server}/%5CBoot%5CPXE%5Cpxeboot.n12

By the way; if you're using pxeboot.n12 or wdsnbp.com, then you're not
using wimboot. They are sort of mutually exclusive. I can see that your
menu has entries for both.
