- All booting under LinuxBIOS will load standalone executables that do not need BIOS calls to access the hardware
There's one important thing missing (though it's implied), which is that LinuxBIOS must *initialise* all the system hardware, as well as providing methods for using it.
This is a step that most people don't see. My observation that this is what actually takes up much of the time (it certainly seems to create a lot of traffic on the list).
