I have tried to build compressed kernels ala Linux (yes, I need more
space on my fixit floppy!). All I got is a crash when booting the
compressed kernel. This is not surprising if you look at the start
code I used :-)

	    .text
	start:
	    call _kunzip
	    jmp _new_kernel   

There is no problem if I link whith 'main(){kunzip();}' and run as a
'normal' program instead of the .S code above, so I conclude that I
have to use a more complex start code!

Unfortunately, writing this is far beyond my capabilities.  All my
knowledge in assembly programing is resumed in the 2 lines above!

Any helper?
