I'm using the patched LILO to boot off the flash, and works like a 
charm (there is a limit to the size of the kernel, though).  It was a 
bit difficult to patch lilo version 21, and create all the necessary 
files, but it now works.

Not everybody can afford DOS for each of their units, and freedos 
isn't exactly ideal, at least with the bit I played with it.

I'm attaching my patched lilo-21, my patch file, and the boot.b file.
Feel free to use it.
