Okay.  That kinda sucks.

These three sentences seem contradictory.  I guess I will look again.
The tftp block number is 2 bytes or 16-bits.  That allows me to address
up to 32MB of a single file.  If my initrd is 33MB, I don't see how you
can address the last 1MB.  There must be some magic I'm missing.

Yes I would agree with that.  I noticed one post about mtftp and
supporting that RFC.  Of course that is more complicated.

Thanks!
