Boot Floppy

Good Afternoon,

I created a boot floppy that brings up a network stack. This floppy works
fine in virtually all PC Compatible platforms I've tried. However, if I make
an image of this floppy and use PXE to download it and execute it, it will
not complete the boot process on a platform where it will boot from a
physical floppy drive. Any ideas how I can fix this?
