Build

• Step1: Installing Linux Toolchains on Windows

docker run --rm dockcross/linux-x64 > ./cross-linux-x64
chmod +x cross-linux-x64
sudo mv cross-linux-x64 /usr/bin

• Step2: Creating an OS Image (os.img)

1.Use bximage.exe (in the Bochs directory) to create an empty img (os.img) of 100MB
2.Use FreeDOS within Bochs to Format os.img to the FAT 16 file system

• Step3: Compiling Using Makefiles

make -f Makefile.windows lib
make -f Makefile.windows os-boot
make -f Makefile.windows build-kernel
make -f Makefile.windows os-loader
make -f Makefile.windows fat16-examples

Use Makefile for Linux users
Use Makefile.windows for Windows users

• Step4: Placing Artifacts into the Mounted Drive

  • Artifacts to be placed:

  boot/kernel.bin
  examples/fs/user1.bin
  examples/fs/user2.bin
  examples/fs/ls
  examples/fs/data.bin
  

  • Use OSFMount to mount os.img and create a drive

• Step5: Starting the OS

make -f Makefile.windows qemu-os

FreeDOS
FAT 16
