My own 32-bit x86 operating system!
Right now, FernOS is just a kernel. There is no shell/UI.
To run code, edit src/u_startup/main.c. This file contains the main function of the first
user process.
To create more processes and perform other system operations,
see src/u_startup/include/u_startup/syscall.h.
NOTE: In its current condition, FernOS has no disk driver. The build process uses qemu's
-kernel flag to boot directly from an ELF file.
# Build and run FernOS in qemu
make qemu.bin
# Clean all build artifacts
make cleanThe above make commands will only success if you have the i686-elf-binutils and qemu.
