Here are the patches (without the serial name fix). Let me know if you want
me to change that. Oh, FYI, my changes also open up the com1 terminal in raw
mode, which makes the emulation much more accurate. You'll also notice that
I added infrastructure for com2->4 in the option parsing. I didn't add it to
the serial code, as I think a bunch of things need to be untangled before
that can work.
- all bochsrc option names changed to lower case, since the uppercase
versions will not be recognized.
- BIOS is now named BIOS-bochs-latest instead of by date.
