FenOS is a Hybrid Operating System,using a exokernel as an operating system kernel, that allows you to use any software made for Microsoft, Apple, Linux/Unix and Solaris natively without being forced to use any middleware. It is compartible with all common hardware architectures such as x86, x86-64, POWER-PC and ARM.
