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
	http://www.washingdishes.freeuk.com/grubtut.html
	http://my.execpc.com/~geezer/osd/boot/grub-how.txt

>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.
