I know that at least someone here is a hacker, how would you open and write to ring 0?

Write a driver.

Care to go in deeper detail?

The easiest way you can access ring zero is by writing a device driver that will run in kernal mode. Go read up on assembly and C. I think Microsoft has provided resources for developers.

Hey man, we don't mean to scare you off or anything. It's just that what you are asking for requires a lot of skill.

I know it requires skill, but the harder something is the easier stuff will be once you do it once. And you didn't scare me off. Have any of you actually had a program run off ring 0?

I did assembly on 8080 chipsets as part of uni studies about 20+ years ago. Essentially programming at the register level.
Generally software design has evolved to the level of mechanical engineering did some 150 years ago. Instead of going and building your own toolset and building a steam engine from scratch, tools became standardised, parts became modular and things became easier to build and deploy quicker.
Software design is now far more modular and it is about knowing which parts of a library to use to implement a solution... for a lot of developers. There is more overhead for doing it this way. So if you have a lot of time and ability you can make something leaner.
Those who are going down to the lowest levels are generally the ones creating the software to directly interact with the hardware. Definitely some of the most hardcore engineers left.

I did have a "driver" in uni that didn't do anything other than sort numbers and matrices using virtual hardware. LC3 is a good way to start, but it is really basic in terms of what you actually have to do when working with a real OS.
