Actually, you can also write your entire program on the floppy. This is not
what I do, but RedBoot is loaded this way and it is quite big once you have
included the network drivers. Plus I my _start is now at 0x2000 because i
had'nt enough space for the network buffers on the startup stack (which is
still located in front of start which is not very)

For Redboot, i've adopted to load RAM program above 1Meg.
