    EXIRION/OS

    Embedded Operating System

    ...These operating systems are designed to be compact, efficient at resource usage, and reliable, forsaking many functions that non-embedded computer operating systems provide, and which may not be used by the specialized applications they run. They are frequently also referred to as real-time operating systems, and the term RTOS is often used as a synonym for embedded operating system. EXIRION/OS project, a Open operating system for computers that can be used in specific operations that require execute a task at a time, EXIRION/OS operating system is a monolithic and mono layered task, which can be used to control complex electronic equipment without the use of instruments PLC, offering a wide range of electronic and industrial applications, EXIRION/OS is also an educational tool, it is an open source operating system to use it as an example of building operating systems in universities and technical colleges.

    MiniTAK Operating System

    A small operating system, compatible with MS-DOS, written in assemly

    MiniTAK is a small operating system for x86 computers to run in processor real mode. One of the main goals in designing and developing this operating system was to be fully compatible with MS-DOS operating system and its application programs. To minimize the size of this operating system, it is completely written in assembly language and can boot on any 8088 compatible processor. This project is an attempt to develop an optimized operating system which can be used to replace MS-DOS, adding new modern features. ...
