Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

+ firmware replacement from floppy (which requires changing a certain
+ jumper on the motherboard). If you want to do either of these, say N
+ here. If MILO doesn't work on your system (true for Jensen
+ motherboards), you can bypass it altogether and boot Linux directly
+ from an SRM console; say Y here in order to do that. Note that you
+ won't be able to boot from an IDE disk using SRM.
