At the moment, the first part is implemented (Real/Protected/Long mode) and the third part (test SIPI multicore, working on VMWare only) More to follow soon.

1. Edit build.bat to specify flat assembler (FASM) path.
2. Edit startbochs.bat, startvmware.bat and startvbox.bat to locate the executables of these applications. Bochs is included in the repository.

Build and run, it will automatically start bochs/vmware/virtualbox with the included FreeDOS image. It will create a CD-ROM as D: and you can run it from d:\entry.exe, by default it is automatically run (autoexec.bat)
