A tiny operating system for i686

• configure: ./config.sh
• create an iso image: ./iso.sh
• run: ./qemu.sh
• clean: ./clean.sh

When creating an iso image, the following command-line arguments are accepted:

Options:
-g                 print the GPL license notification.
-h, -help          print this help.
-v                 print software version and exit.
-j                 the number of jobs

The basic dependencies before building and using this operating system are:

• QEMU (i386)
• i686-elf toolchain (see here)
• GRUB with i386-pc support (e.g. add pc to the GRUB_PLATFORMS flag on Gentoo, install grub-pc-bin on Debian/Ubuntu)
• xorriso (which might be included into libisoburn)
• GNU make v4.0 or later
• A GNU/Linux system for testing

Bare bones:

• boot
• initialize stack and the rest of the environment
• enter kernel

VGA terminal driver:

• support for newline
• terminal scrolling
• render ascii logo

Architecture:

• extensible libk and libc
• make build system support
• hard build system with flexible configuration

The skeleton structure of this operating system was taken from the following guide on OSDev Wiki.
