My patches for FreeBee to allow Unix to install and boot multi-user

I have now released my fixes for FreeBee to allow Unix to install and boot to multi-user mode. They are against revision d91346487fe9 of FreeBee (the last to use the original version of the MMU emulation) and can be imported with hg import. The installer complains about the floppies not unmounting properly, but that doesn't seem to affect anything. Also, Unix doesn't reliably boot to the login prompt unless you remove .lpstartsched from /etc/rc (it's easy enough to do this with a hex editor). I'm not quite sure what the problem is. Starting the print server from the command line doesn't cause a hang, and the system never seems to access the parallel port when the print server is started (be it from /etc/rc or the command line). I think the hang might be occurring somewhere after the print server is started. Another issue is that the ROM won't boot the hard disk at the moment (which I think might have something to do with the head select). The only way to boot the hard disk is to boot from a floppy with a filesystem but no kernel. The install root floppy (NOT the boot floppy) works for this. The floppies are available from Bitsavers (IIRC they are in ImageDisk format, meaning need to be converted to raw format to use them with the emulator). As currently configured, the emulator is hardcoded to use a hard disk image that is 67108864 bytes in size.
