Preemtive multitasking, after hours and hours of debugging.
The scheduler is not complete yet; it doesn't save the state of a task before switching to the next task, and so always starts execution at the beginning. I have all night to finish it.

Wow, and here I thought you'd be working in assembly forever! What made you decide to move to C?

When I decided to create an x86 and x86_64 OS mostly from the same code. Porting my OS to x86_64 now would only require changes in the initialization and paging code.

Basic 320x200 VGA driver. With 256 (64) colors.
Drawing test: basic "desktop" with filled and outlined rectangles + z order.

It's funny to see everybody with a nice GFX gui and I'm not even capable of changing the video mode toVESA with grub

Yeah. I mean, I can change video modes, but thats about all. I've been trying to tackle basic stuff like gdt idt and keystrokes. at least you have a good system laid by now.

Yeah, you need to have some foundations. For beginners GDT and IDT aren't easy task. You need to make your OS step by step, you can not have graphics mode right after you start. But once you get something to work, you get an amazing feel of happiness and satisfaction, you know you've achieved something.

I agree, in my last OS, I use the code of someone eslse for the GDT and IDT, but now I'm making my own

But it's realy not eazy.

do you know a good tutorial for IDT and GDT (in c if possible)
