## About
|
|
ExectOS aims to be a stable and flexible, general purpose operating system written from scratch. It is designed to be
|
|
modular, maintainable and compatible with existing software. It implements a brand new XT architecture and features own
|
|
native application interface. On the backend, it contains a powerful driver model between device drivers and the kernel,
|
|
that enables kernel level components to be upgraded without a need to recompile all drivers.
|
|
|
|
## XT Architecture
|
|
ExectOS is a preemptive, reentrant multitasking operating system that implements the XT architecture which derives from
|
|
NT™ architecture. It is modular, and consists of two main layers: kernel and user modes. Its' kernel mode has full
|
|
access to the hardware and system resources and runs code in a protected memory area. It consists of executive services,
|
|
which is itself made up on many modules that do specific tasks, a kernel and drivers. Unlike the NT™, system does
|
|
not feature a separate Hardware Abstraction Layer (HAL) between the physical hardware and the rest of the OS. Instead, XT
|
|
architecture integrates a hardware specific code with the kernel. The user mode is made up of subsystems and it has been
|
|
designed to run applications written for many different types of operating systems. This allows us to implement any
|
|
environment subsystem to support applications that are strictly written to the corresponding standard (eg. DOS, or POSIX).
|
|
|
|
## Features
|
|
* Completely free, Open Source and community-driven modern Operating System.
|
|
* Native multiple architecture support. It runs on x86 and x86_64 and is portable to other architectures.
|
|
* Hardware layer API allows for a single unified kernel. There is no need to maintain a separate kernel forks.
|
|
* Uses a couple of ideas from other open source projects, but it’s our own ideas that really sets us apart and defines
|
|
ExectOS. The majority of code is original, not forked.
|
|
* Modular design for better compatibility with existing software and drivers, enabling binaries to remain compatible even
|
|
when the core system is updated.
|
|
* Own, XT drivers for commonly used devices as well as NT™ drivers compatibility layer for better hardware support.
|
|
* Technical support directly from the architects and developers of the system.
|
|
|
|
## Why
|
|
* We believe, there is no ideal Operating System on the market. During ExectOS development, we try to bring most useful
|
|
features known from existing solutions, while keeping compatibility with NT™ architecture at desired level.
|
|
* Some of our ideas differ greatly from other projects and it is much easier if we do not have to fight legacy code and
|
|
ideas.
|
|
* We need the freedom to break things when necessary.
|
|
|
|
## Goals
|
|
* Keep the greatest advantages of the NT™ architecture, while implementing new features and technologies known from
|
|
other Operating Systems.
|
|
* Flexibility where it makes sense to provide flexibility.
|
|
* Be able to deliver features that other non-commercial Operating Systems consider too ambitious.

## Requirements
|
|
ExectOS is in very early development stage, thus its requirements have been not specified yet. However according to its
|
|
design, it requires a modern EFI enabled hardware. It is not possible currently to boot ExectOS on a legacy BIOS.
