🛠️ Invoke Windows Native API syscalls directly with Syscaller, a header-only C++ library that ensures compatibility and avoids breaking updates.

🔌 Divert system power from S5 to S4, S3, or reboot, enhancing wake-up options while reducing reliance on the power button.

🔍 Explore QEMU CPU models for KVM guests to enhance performance in single-node homelab setups with AVX2-capable processors.

💻 Boot and load `IO.SYS` using this x86 real mode bootloader, designed for FAT16 filesystems, with an easy setup in a reproducible environment.

🧮 Build simple calculators in various programming languages to understand basic syntax and math operations while enhancing your programming skills.

XuNet OS is 32-bit operating system with XuNet Kernel built entirely from scratch using the custom XuNet kernel. Designed for simplicity, speed, and low-level learning, it includes its own bootloader, memory management, and a minimal command-line interface—ideal for OS developers and enthusiasts exploring system internals

Low-level utility library designed to provide direct access to hardware and memory operations for embedded systems, operating systems, and performance-critical applications where low-level control and performance optimization are crucial.

this is just a webring for people passionate about operating system development (or even just low-level stuff). if you're working on an OS, writing low-level code, or just love tinkering with the bare metal, this is the place to connect!

These tools were originally designed to be a research project and drop-in replacement for readelf, objcopy and objdump utilising Capstone disassembly framework.
