Help with binary (loops?)

Writing a simple O/S takes many hundreds (maybe thousands) of man-hours. If you're finding it a 'bit tiring' at this point trying 10+ examples then you have a problem. I'm not sure you will make it.

I think there is a difference between searching and coding.

It is also on the wiki.

Where do you see THESE baby steps in there:

Step 1: How to enter the real mode
Step 2: Using C++ write/access vid mem
Step 3: Any compile/link options?
Step 4: Making sure that runtime error won't appear

You gave me asm not c++

If you read the articles perhaps you can find the information you need.

Go a bit down, there is the code to return in real mode. Oh yes no C++ code here, some operation are better performed in ASM.

Step 2: Using C++ write/access vid mem

With a pointer? The video mem is mapped in your ram at the addresses you can find in the wiki
However... 0xb8000 physical address for textual modes and 0xa0000 for graphic modes. This is all.

I used TCC too to write my bootoloader, but I got no error at compiling time and linking time. Can you show us your current configuration?

Yes, and programming involves both. Get used to it.

Step 1: How to enter the real mode

The CPU starts in real mode. Unless you have already entered protected mode, there is no reason nor necessity to enter real mode.

How do you compile 16 bit exe with model tiny in MinGW to be converted with exe2bin?

As per forum rules:

Describe the goal, not the step

If you are trying to find out how to do something (as opposed to reporting a bug), begin by describing the goal. Only then describe the particular step towards it that you are blocked on.

Often, people who need technical help have a high-level goal in mind and get stuck on what they think is one particular path towards the goal. They come for help with the step, but don't realize that the path is wrong. It can take substantial effort to get past this.

It has been said before: if you keep insisting doing it your own completely broken way, you will get nowhere. Either suit yourself and go somewhere else so you stop annoying us, or at least try doing what the dozen working options do before complaining about anything. If you want to claim you have actually completed each and every tutorial out there within the past two days we will all know its a lie.

And since subtlety did not work so far: Do as instructed or GTFO.
