Welcome to the Fiwix project
Your small UNIX-like kernel


The FiwixOS 3.2 Installation CD-ROM includes the binary form, the source code and the patch file (if needed) of every single package installed in the system. It also includes the kernel source code and a set of example programs to stress and test some kernel features. The CD-ROM is shipped in the form of a live operating system.

The FiwixOS 3.2 Flat IDE Disk Raw Image contains a pre-installed FiwixOS 3.2 system, for use in virtual machines. Changes made to the system are persistent.

Example of installing FiwixOS 3.2 on a hard disk by booting from the Installation CD-ROM (using QEMU):

qemu-img create hd.img 1G
qemu-system-i386 \
	-drive file=hd.img,format=raw,cache=writeback,index=0 \
	-drive file=FiwixOS-3.2-i386.iso,media=cdrom,index=2 \
	-net none \
	-boot d \
	-enable-kvm \
	-machine pc \
	-cpu 486

Either on a virtual machine or in real hardware, let the system boot and when you are ready just type:

If you plan to install FiwixOS 3.2 on a very old hardware (i386 or i486), you might want to use the floppy disk as a boot media in case the BIOS is not able to boot from CD-ROM.

WARNING: the kernel and the software included might contain (un)known bugs and vulnerabilities.

There is an archive of old FiwixOS versions here.
