Fiwix is an operating system kernel based on the UNIX architecture and fully focused on being POSIX compatible. It is designed and developed mainly as a hobbyist operating system, but it also serves for educational purposes. It runs on the i386 hardware platform and is compatible with a good base of existing GNU applications. It follows the System V Application Binary Interface and is also Linux 2.0 System Call ABI mostly compatible
The FiwixOS 3.1 operating system is a Fiwix distribution. It uses the Fiwix kernel, includes the GNU toolchain (GCC, Binutils, Make), it uses Newlib v3.2.0 as its C standard library, and Ext2 as its primary file system.
