I'm trying to reproduce this but can't find any documentation for
cross-LILO in [2], much less any code except possibly the binary
"lilo.x86" in [1]. Googling cross-lilo isn't finding anything
meaningful except this thread. Is there anywhere to find source and
information on what it's doing, or is this going to be something I
have to reverse-engineer?
