[syslinux] Comboot Menu

[ganapathy murali krishnan]

OK. For now, I will hard code the menu entries in a variable and worry 
about reading files for later.

The only thing I will be using from the C library is printf, that too 
only for debugging. All print statements will happen through appropriate
BIOS calls. All debugging prints will happen through printf. Once I am 
done, removing the printf statements will be trivial.

Is there any comboot program which reads files out there? Then I dont 
have to re-invent the wheel.

PS: I think I am almost done with the simple menu interface. It accepts 
the arrow keys, Enter and ESC. Ignores all other key strokes.
