Arrgggh.... bugs everywhere... My framebuffer display driver made a booboo, that's one thing, but the debugger is not perfect either :oops: As you can see backtrace is not shown properly (there are 3 more text segment addresses on top of the stack that should be there), and the disassembly is also more than interesting...

Not really a bug. I was trying to fill the screen with characters and didn't read the VGA spec that each character is 2 bytes with one of them being a modifier sooooo I got this

Not bad for my first attempt in rendering a page delivered over HTTP.
Image

Not sure exactly why are those "href" attributes are being parsed as text and not attributes, but have many weeks to investigate.

UPDATE: A failed attempt on rendering my favorite forum.
Image

Most of this really was fixing the TCP/IP stack and not actual work on the browser itself, because my TCP/IP stack had problems when the server doesn't send the response packets in order, while the majority of sites do not actually send their packets in order. Then, when I finally had an "aww yeah" moment when my TCP/IP stack worked properly (but really slow,) I was hit with the fact that my rendering doesn't handle line overflows properly neither tables.

When you mess up a for loop while setting the page tables:

Apparently it ran into hardware memory.

No, this is not yet paint :D This was supposed to be mouse cursor moving on black screen. Seems my repaint function is buggy and when mouse moves down, it draws a white line :D

I replaced my kmalloc() workings with something spicier and this happened...
You can actually see the pink BSOD (more like PSOD hahaha) and I have no idea what went wrong. I suspect some corruption in the double buffering mechanism for VESA.
:(

Looks like some kind of ASCII game or something.

I see a lot of strange vga text things. I used to get that because of an overflow in my command buffer.
