Need help with an OS

[Ocawesome101 1]

Okay, so here's my problem.

I am trying to make my own custom OS for OpenComputers. However, I am having issues with the GPU displaying on-screen.

I have code that should, as far as I can tell, do what I need it to, but doesn't.

How to reproduce:

Download the attached .lua files, and put them on a floppy disk. Place init.lua in the root directory (of the floppy), and boot.lua in sys/boot/ (so the files on the floppy should be /init.lua and /sys/boot/boot.lua). Boot from the floppy, and you will see what I mean.

If anyone can help me, or knows what I can change or look at, your help would be greatly appreciated

Before you ask, I have already looked at the Wiki entries on Component, GPU, Screen, Writing Custom OSes, and that one forum post about 'Custom OSes under OpenComputers' Lua architecture'.

 

I am probably a moderate to intermediate Lua programmer by now, and this code is the result of around an hour of work.

 

Thanks in advance!

boot.lua

init.lua

The thing is... there is no error. There is only a black screen - nothing happens.

You never executed the loaded function on init.lua:13.

Also, look at your print function in boot.lua. It won't work. You need to define w, h, cx, and cy outside of the "if not gpu then ... end" block.

Ohhhh, okay. Thank you!
