it is sad in the university people not study how program in assembly
especially the old 16 bit registers one.

it will be interesting a compo for the speed (because it seems it is
the speed the problem and not the size)

or someone could be get one OS break it in 20 - 30 parts
do 20 30 compo and glue them all for doing the smallest(fastest) OS
ever seen :)

the lesson for this compo is that
imul reg, reg, imm
is good because it does 2 operations:
1) does multiplication
2) assign to one register not [e]ax
