A x86 Unix-like OS made entirely from scratch.
Features
- Protected mode (GDT/IDT, ISRs/IRQs)
- Paging and virtual memory
- Memory management
- Heap and dynamic memory
- User-mode (ring 3) and kernel mode (ring 0)
- Processes and scheduling
- Drivers (PIT, RTC, Keyboard, Mouse, Framebuffer, PATA)
- ext2 filesystem
- UI compositor with window widgets, labels, icons, buttons, and even a custom-made font
- ELF loader, which gives you the ability to run real apps
All these features let you run real games, just like Doom, giving the preloaded Doom port in MyraOS ready to be played!
So, this isn't just a toy OS or a look-alike, it's a real OS that can run on real devices
- Download the latest release from the release tab in GitHub
- Download QEMU - an open-source machine emulator and virtualizer
After you get the latest release, you can run this on your platform:
Normal
qemu-system-i386 -cdrom MyraOS.iso -drive file=fs.img,format=raw,if=ide,index=0 -m 1024
Fullscreen (if you are like me and want it to look real)
qemu-system-i386 -cdrom MyraOS.iso -drive file=fs.img,format=raw,if=ide,index=0 -m 1024 -full-screen
Normal
qemu-system-i386 -cdrom MyraOS.iso -drive file=fs.img,format=raw,if=ide,index=0 -m 1024
Fullscreen
qemu-system-i386 -cdrom MyraOS.iso -drive file=fs.img,format=raw,if=ide,index=0 -m 1024 -display gtk,zoom-to-fit=on -full-screen
Here, Linux/macOS or even WSL are better; use it as a last resort:
Normal
qemu-system-i386 -cdrom MyraOS.iso -drive file=fs.img,format=raw,if=ide,index=0 -m 1024
Fullscreen
qemu-system-i386 -cdrom MyraOS.iso -drive file=fs.img,format=raw,if=ide,index=0 -m 1024 -display gtk,zoom-to-fit=on -full-screen
I really hope you like it, as I spent a lot of time on it, and I'd really appreciate any feedback you have for me.
