🐝 Bee Kernel

Bee Kernel is a small educational 32-bit x86 operating system kernel written in C and Assembly. The goal of the project is to explore how operating systems work internally by building core kernel components from scratch.

This kernel is designed for learning purposes and focuses on low-level system programming concepts such as interrupts, memory management, and multitasking.

✨ Features

Current features implemented in v0.1:

• Multiboot compliant kernel
• VGA text mode console
• Interrupt Descriptor Table (IDT)
• CPU exception handling
• Programmable Interrupt Controller (PIC) support
• Programmable Interval Timer (PIT)
• PS/2 keyboard driver
• Physical Memory Manager
• Basic paging support
• Kernel logging system
• Simple task system
• Round-robin scheduler
• Basic syscall interface

---

🖥 Supported Architecture

• x86 (32-bit)
• Tested on QEMU

---

🧰 Requirements

You need the following tools to build and run the kernel:

• GCC (with 32-bit support)
• NASM
• Make
• QEMU
• GRUB (for multiboot)

On Debian/Kali/Ubuntu you can install them with:

sudo apt update
sudo apt install build-essential gcc-multilib nasm qemu-system-x86 grub-pc-bin xorriso

⚙️ Build the Kernel

Clone the repository:

git clone https://github.com/dineshg0pal/Bee-Kernel-2.0.git
cd bee-kernel

Build the kernel:

make

This will generate the kernel binary.

---

▶️ Run the Kernel

Run the kernel in QEMU:

make run

or manually:

qemu-system-i386 -kernel kernel.bin
