[SOLVED] Triple Fault on filling screen.

[zlixine]

Hi guys (noob here) , I am developing a simple text based Operating system here, I am in protected mode, and I noticed when the screen is filled with text, a triple fault triggers, is it a common problem? or did I make a coding mistake?
also I Use the same Debug Text Printing from Brokenthorn Tutorials.
anyway see the attachment to understand what I mean.

Cheers.

EDIT:
I solved it by clearing the screen when it is fill (Temporary of course).
also about the triple fault , it looks like, I fucked up the GDT by mistake, I fixed it and it worked.

Thanks for you Attention.

I took a quick glance at the text output code and saw this line:

Code: Select all

if (cursor_y >= 25)

That should probably be 24, since the screen is only 25 lines, and it's zero indexed, so your cursor Y should only go from 0 to 24. Try just replacing the ">= 25" with "> 24" and see how it goes.

Also, just a side note, the repo needs a bit of a clean, you've got a .gitignore file in there, but you still need to git-rm the leftovers that are being tracked or otherwise remove them from the repo.

Didn't Work , it still restarts the emulator.

Yes, I am aware of this, and I am planning to fix it soon.
