Clarification: that limit comes from the fact that the Syslinux core is
a "tiny model" program (single 64K segment). The PXE spec itself limits
the downloaded program to 32K (this was actually the reason for basing
PXELINUX on SYSLINUX), but it turns out that no known PXE stack depends
on that limit, and in practice one can load at least a few hundred K.
