Resources Used

Building & Running

NOTE: This has only been tested in an emulator. Real hardware might not like it.

EDIT: this is not true anymore! @parkerlreed has run this on a Thinkpad T510.

Mac OS

For the cross-compiler: $ brew tap nativeos/i386-elf-toolchain && brew install i386-elf-binutils i386-elf-gcc

To run use $ make qemu-mac

Unix-like

You should not need a cross-compiler in most cases as the gcc shipped in most linux distros will support i386 targets.

If this isn't the case for you, read here about getting a cross-compiler.

To run use $ make qemu-pulse

If you have sound device issues, try the SDL backend for QEMU with $ make qemu-sdl or disable any audio devices with $make qemu-no-audio

If you're having issues with no image showing up/QEMU freezing, this is a known bug with QEMU SB16 emulation under GTK. Please read what @takaswie has written in #2 for a workaround.

Windows

Good luck. Maybe try dual booting with Linux if this doesn't work out :)

  • Follow the Unix-like instructions while using WSL
  • Using MSYS2 and the i386-elf-toolchain
    • Extract the binaries of the GCC and binutils releases to your mingw64 folder (likely at C:\msys64\mingw64)
    • make, gcc, etc. should now be in your PATH
> make img
> qemu-system-i386 -drive format=raw,file=boot.img -display sdl -audiodev id=dsound,driver=dsound -device sb16,audiodev=dsound

If sound is broken or choppy, try running with > qemu-system-i386 -display sdl -drive format=raw,file=boot.img -audiodev id=dsound,driver=dsound,out.fixed-settings=on,out.frequency=22050,out.buffer-length=80000,timer-period=100 -device sb16,audiodev=dsound

Real hardware

You probably know what you're doing if you're going to try this. Just burn boot.img onto some bootable media and give it a go. The SB16 is dynamically disabled in case it's not found or it's reset procedure fails, but if things continue to break try removing all references to sound or music first.
