This topic is too young to die. Please guys post some more pictures of your OSes.

Okay. Here's something I've been working on for the past day or two:


The start of some userspace debugging utilities. Many more coming!

Very cool!

Cool "little" terminal, I assume you are using some sort of print function, how did you change color of your text to purple-ish.

You have (on boot) 16 colors to choose from, and how you set the colors is very easy, http://wiki.osdev.org/Printing_to_Screen explains it all.

If you're asking how the colors are actually displayed on screen, then yes, that's just the regular tricks. If you're asking how the shell communicates that it wants colors, that's just bash being told to color the prompt, and it uses escape codes to tell the terminal that it wants something colored.

Hi!

Wow! 2000 posts! We made it so far!

Let the fun continue!

My OS

I've been working on the gui most recently, something I haven't done before, quite pleased with how it's coming.

Its veeeery impressive what I've seen here, but where did you all learned this D:

Once upon a time in DOS i saw a bat file.
In it were series of commands. If you press it, it would run these commands.
Meh.

But there was one bat file that asked questions - press 1 for one program, press 2 for the other.
In it was a command called choose and something about errorlevels, and it was doing something with % symbol...

That was mysterious.
A concept floated around, that i couldn't quite catch.

Then, i saw a bat file that did something miraculous - it "assigned" text to a % name, and that % name later was checked against a string.
And. it. went. different. ways. whether. it. was. the. same. or. not...!

That was The Concept.
You can make a computer do things like this!

I was 12 at the time, and it all went downhill from there...

I meant all the things like drivers, GDT, IDT, IRQ, Protected Mode, and so on, where did you take the information for this?

Most people here learned this from research (architecture reference manuals such as the Intel or AMD64 manuals, our wiki, compiler manuals, etc) and from asking questions when research falters. For things like graphics, once you have a framebuffer and details (eg, stride, pixel size, color mode) much of the coding is pretty much the same as non-OSDev graphics.

After a certain point, most of the work turns out to be basically application development anyway.

FWIW, my screenshots come after the project has existed since early 2008

Got my OS booting from harddisk ( using an initrd ):

It's just a mistake, I think. Obviously, he doesn't know.
