PXE BIOS's don't need a pxe server. They just use dhcp and tftp
to pick up a program to load at 0x7C00 and then jump to it.
The only thing that's different about PXE BIOS DHCP's is that they
set the vendorclass to something starting with PXE.
PXE BIOS's do provide a 16 bit interface for doing further tftp's
etc but, since 9load already does all of that in 32 bit mode, there's
no real reason.
9pxeload is just a 9load that knows that it gets loaded at a
different location and that has to shift from 16 bit mode
to 32 bit mode when it starts.
