I did not claim to have invented anything there, this is just a quite
simple C code to execute instead of the current real mode assembly:
it is a rewrite with obvious advantages/disadvantages.
New features are more that this real-mode function can return an error
to the bootloader to tell something to the user, so the user can select
another kernel with the right processor, another video mode... with
clean error messages - not a crash dump because this assembly
instruction is not for that processor.
I am still saying that the bootloader knows the root filesystem to
be used by the kernel it loads, and that ELF is a clean format to
store different sections to be loaded into memory at predefined
addresses. Also there isn't any more kernel size limit.

Etienne.
