On the ST doing ctrl-alt-del reloads minix from disk. 
This is caused by the fact that bytes 0-7 of the ST memory are
not writable hardware locations. If you look in tools/boot.s you'll
see that the first 8 bytes are not copied to low mem.

In order to get ctrl-alt-del working as expected the 
been_here problem should be solved and line 330 of 
kernel/stmpx.s should be changed from
        jmp     (a0)
to       
        jmp     _start
Perhaps this should be accompanied by an #ifdef. 
I don't know exactly what the amiga and mac ports of minix will
do or use from this file.
