No, this is not the main reason why your code is wrong. The main reason is that characters and strings are different things and you ignore that.

Except i'm in protected mode.

Hardware interrupts are a thing in protected mode.

So what?

We don't have the default real mode/V86 interrupts here in protected mode.

Hi,


He didn't mean real-mode interrupts. See PIC (programmable interrupt controller) and Exceptions (protected-mode reserved interrupt vectors).

But anyway, next time you should search more thoroughly. This is well-documented stuff.

I'm sorry but you really, really don't have the required knowledge for OS development. And the sad part is that you seem totally unable to learn.

As they told me in my early days of me being on this forum, here spoonfeeding wouldn't get you anywhere. Isn't it enough spoonfeeding? Okay, there is one more spoon...

Strings are pointers to arrays of characters, which by most, if not all standards end with null terminator character (character of value 0).
8-bit characters are one byte integers used in user input and output most commonly used with ASCII, e.g. letters A-Z, numbers 0-9, many interpuction signs, some teletype instructions and text art symbols.

***Tries to write an OS without understanding most programming concepts.***

It may be very hard to stop yourself from your dream and goal, but you are 9 and should realise, that most of projects, including the ones not related to programming and computers, fail, especially those hobbyistic, goal-less and ones that does not make money. At least you made some experience.
Now you are ready to press that "Delete account". We may miss you couple months at least.

x86 CPUs support the same 256 interrupt vectors in any processor mode.

Oh, you mean you can't use the BIOS interrupt handlers any more? You don't need them anyway.
