We have text!

Some text displaying the system info.
     Started off the day by getting some graphics going.  I had to edit a frame buffer, which basically represents every single pixel's color.  1024 (width) * 768 (height) = 786,432 pixels!  And each pixel has a 16-bit color code, so this frame buffer takes up just under 1.6 MB in memory.

     After I got the hang of drawing graphics, the next step was drawing text.  This site gives a download to a couple of bitmap fonts.  Each letter consists of a 16x8 bitmap representing a character.  Through some trickery and basic string manipulation, we were able to draw text!  Next up, a basic command line!

As always, you can find the kernel to the left, at "How to put JoeyOS on your Raspberry Pi!"
In addition, the photo gallery will hold all screenshots and development photos.
