Cylix OS is a lightweight operating system/firmware designed for single board computers. It provides a minimal environment for running bare-metal applications with basic timing and scheduling capabilities.

Features

• Bare-metal 32-bit x86 environment
• Simple cooperative multitasking scheduler
• Millisecond timer implementation
• VGA text mode display output
• Modular architecture for easy customization

Building

To build Cylix OS, you need:

• GCC cross-compiler for i386 target
• NASM assembler
• GNU Make

Build steps:

1. Clone this repository
2. Run make in the root directory
3. The firmware binary will be output to build/bin/firmware

Running

Cylix OS can be run on:

• Real x86 hardware
• QEMU x86 emulator

To run in QEMU:

qemu-system-i386 -kernel build/bin/firmware
