<aname="l4"></a>fork of ZenithOS, which itself is a fork of TempleOS. It can run on some bare metal 64-bit PC's from about 2007-2019 with no
<aname="l5"></a>layering, libraries, tools, modules or anything from other sources. Otherwise, you run it in a virtual machine, like </span><spanclass=cF2>VMware</span><spanclass=cF0>, </span><spanclass=cF2>Q
<aname="l6"></a>EMU</span><spanclass=cF0> or </span><spanclass=cF2>VirtualBox</span><spanclass=cF0>. It is independent and stands alone. 100% of the src code is including on all distro's, from the kernel to
