Mike,

The problem is that the client side needs to know the size of the file
to allocate memory for it. By default, the TFTP protocol has no
command to ask for the size of the file. To work around the problem,
the client can load the file a few bytes at a time just to calculate
the size. Once the size is known, the allocation is done and the
file can be downloaded for real.

The ATFTP adds the support to ask for the file size, therefore you save
one download of the file. Note that elilo has the same thing when it
downloads any file from the network.
