Welcome ! It seems you are intrested in my Melon OS... ** HOW TO BUILD MELON : ** This is supposed to work in a Linux environment. Maybee it could work on *BSD, or Cygwin, but that wasn't tested. You need : - GCC - Nasm - Qemu or Bochs for testing (Qemu works better, debugging is planned for bochs) If you haven't yet downloaded the source code, then commit the GIT repository : $ git clone git://github.com/Alexis211/Melon.git Then, rebuild everything : $ make mrproper $ make Create the floppy image : $ make floppy You will probably be prompted for your password. We need it to mount the floppy image as a loopback device. And run it with Qemu : $ make qemu
