	Basicly you are right. But lilo makes extensive use of *real* BIOS
functions like int13, int10, int16, and some strange
int15-shift-this-memory-to-ems function that I forgot the functioncode of.

	I´d rather do this in C and burn a barebone Kernel onto my Disk ...
	But I´m not sure if I kill my own running environment by copying a
Kernel to mem at 0x10000. Furthermore I have no idea if the
segment-deskriptor-setup is suitable for an immediate start of a kernel
image ...

	I´ll try this tomorrow and keep you up to date if I succeed on this
