MOS

MOS (My Own Operating System) is a text-mode kernel that includes the essential components required to boot up and interact with motherboard devices and drivers.

MOS is more than just an operating system—it's a platform for learning, innovation, and experimentation. Whether you're interested in OS development, or simply exploring the inner workings of your computer, MOS provides an environment to bring your ideas to life.

Key Features:

• Lightweight and Minimalistic: MOS focuses on minimal resource usage.

• Direct Hardware Access: Provides low-level access to system hardware, offering a deeper understanding of how operating systems interact with hardware at the core level.

• Built-in Security: Features security measures, including user-space separation, memory protection, and privilege levels to safeguard the system and user data.

• Task Management: Supports efficient multitasking with preemptive scheduling to manage real-time tasks, ensuring smooth performance even in resource-constrained environments.

• Virtual Memory Support: Implements memory paging and segmentation (including support for the GDT), enabling advanced memory management and protection.

• Local Device Drivers: Includes a list of local device drivers such as ATA, Mouse, Keyboard, Network Card, and VGA drivers.

• Built-in Network Layers: Implements basic networking protocols, including EthernetFrame, ARP, ICMP, IPv4, and TCP.

Designed For:

• Learning and Development: MOS is designed to provide deep insight into how OS components work together, making it an excellent tool for learning low-level programming, kernel design, and system architecture.

• Custom Workloads: If you need a custom OS for experimenting with operating system concepts, MOS can be tailored to meet your needs.

Development Environment:

• Written in C++: The core system is written in C++ for efficiency, low-level hardware control, and object-oriented features.

Requirements:

• Linux operating system
• GNU tools (Assembler, G++, Linker, [binutils, libc6-dev-i386])
• VirtualBox (VM)
• GRUB Bootloader
• Make tool

Core Components:

• Kernel: The heart of the operating system, responsible for process scheduling, memory management, hardware abstraction, and system calls.

• Device Drivers: Provide support for a range of hardware components, including storage, networking, and input/output devices, offering direct access to hardware resources.

• Network Protocols:

  • Data Link Layer (Ethernet)
  • Network Layer (IP)
  • Transport Layer (TCP, UDP)
