Writing an OS can be fun, but writing a bootloader is not
as fun, interesting, or easy as it sounds. Use the GRUB
bootloader instead:
http://www.gnu.org/software/grub/#download
ftp://alpha.gnu.org/gnu/grub/grub-0.92-i386-pc.tar.gz

>1. How to get Flat format?
Do you mean binary output? If you use the "aout kludge",
GRUB will load a 32-bit OS in any file format, including
DJGPP COFF. So you don't need binary output.
>2. Is this (Flat format or COEFF) directly executable?
The CPU must be in 32-bit mode (protected mode) to run it.
GRUB will also do this for you.
