Why? If you use your own boot loader on the latter systems, you don't
have to use the Multiboot-style booting method on them. So you should
be able to have your OS image to have different startup code both for
real PCs and for old and embedded systems simultaneously. Note that
you can distinguish if your OS image was booted by a
Multiboot-compliant boot loader or not, by examining the value of the
register EAX.
