🌫️ Mist 🌫️

---

Mist is a simple x86_64 operating system made from scratch, that can work on real hardware (in combination with Minit; Checked on Acer Aspire E5-532)

This training project made for learning how the PC works. Every bug fix and improvement are welcome, so don't be shy to contribute. It uses MIT license so you can do anything with this code!

---

What can it do?

• Boot with own bootloader - Minit
• Control physical memory using PMM
• Manage virtual memory using VMM
• Handle interrupts using IDT
• Listen keyboard using keyboard and PIC drivers
• Output anything to VGA using VGA driver
• Process basic shell commands
• etc..

It uses Mistic - own freestanding C standard library

There is documentation to explain you every function in code

In future...

• PIT driver
• Multitasking
• Disk driver
• Own VERY simple ext-like FS
• Third-party programs starting
• Ring 3 and userspace

All new features and changes will be posted first to my Telegram channel
