It doesn't affect the portability at all. The BIOS function set is the same on
any IBM compatible PC no matter which OS you're using (At least functionality 
is the same, not hte code) . It is stored in an (EP)ROM on the mainboard 
of a PC. The BIOS functions are just used for low level hardware stuff such 
as reading/writing a disk sector, using COM and LPT ports, receiving
keyboard input and so on. These functions do not depend on the OS
that is running on the computer.
