TFTP is not really the best choice for this. You'd want a network
protocol which can support random access.
MSCDEX, which uses the DOS "redirector" (installable filesystem)
interface is not really the right thing to mimic if you want to mimic a
floppy or hard disk (like MEMDISK); rather, you'd want to be a DOS block
device, or even lower level -- mimic MEMDISK and talk to the PXE stack
beneath an INT 13h interface.
Any reason MEMDISK doesn't do what you need?
