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. -- geezer@ | http://www.execpc.com/~geezer execpc.com | http://www.execpc.com/~geezer/osd
