x86system

x86system is a hypothetical open-source operating system platform designed to run on x86-compatible hardware. The project emphasizes a clean, well-documented codebase suitable for education, experimentation, and research. It targets both 32-bit and 64-bit x86 architectures and provides a POSIX-like user space with familiar development tools. The platform includes a boot loader, a kernel, and a standard userland, along with a package manager and tooling for building and deploying components. The design goal is portability across generations of x86 hardware while offering a straightforward development model for students and professionals.

At its core, x86system uses a monolithic kernel with modular subsystems for memory management, process scheduling, and device drivers. The kernel provides a hardware abstraction layer to simplify driver development across PCIe, BIOS/UEFI, and chipset configurations. It supports multi-core symmetric multiprocessing, thread-level parallelism, and modern paging with optional large pages. The userland includes standard libraries and utilities to facilitate porting software from other POSIX systems. The platform supports virtualization extensions and can boot in either legacy BIOS mode or UEFI mode.

x86system is developed under an open-source license with active community governance. The project maintains a public repository with issue tracking, contribution guidelines, and regular releases. Documentation covers architecture, API, boot process, and developer guides. The project encourages educational use, hands-on kernel development, and experiments with hardware drivers.

Because it is experimental and educational, x86system is primarily used in classrooms, labs, and research environments for teaching operating system concepts, kernel development, and driver programming. It is not intended as a drop-in replacement for mainstream operating systems but serves as a platform for learning and experimentation around x86 hardware and system software.
