Everything up to the start of main() works like a normal kernel starting but
then I just write some simple text to screen and exit but Windows/DOS/Linux
Kernels do a lot more. So I have a bootsector, a loader and a C program that
can be loaded in the same way any OS starts it kernel.

Which FAQ? Also DS is loaded in loader with a Pmode descriptor that has a
base of 0x0000 and in Pmode adding 0xb8000 the correct place to fine the
video mem.

Any more help...
