i am no turbo C expert
but, perhaps you could write it as a tiny model (.COM) program

No, I want to build a OS, not a Windows 3.11

I personally recommend against flat binary kernels tbh. I would just parse the output executable of the compiler and linker of your choice and use that.

If you really want to go flat binary, you might be able to use exe2bin to convert the EXE to a flat binary. Or, you can just use a .COM file (its a flat binary) if Turbo C supports it.

Nathan,
DednDave is right. Compile in TINY memory model and link to a COM file (TLINK can do this without EXE2BIN). Provide your own C0T.OBJ with ORG 0 (or ORG anything you like) instead of ORG 100H. Write a bootloader to load this file from your boot disk.

Edit: fixed typo.

Very nice!
I'm going to test this and post here what I got.

I agree with you but I wouldn't recommend MZ-EXE.

Nathan,
Good luck!

Hello,

While I would agree that EXE might not be best for beginners here, I would encourage anyone to use what is best for their projects' goals, whether it is EXE or not.

Then the OP may like BootProg.

That's an awesome tool, but someone here already tried to use it?

Also, using Turbo C, as the compiler and BootProg as my bootloader. I can do a OS running VESA mode(or like VESA), as Windows 3.11?

Best Regards.

Could you please isntead of make jokes, help me?

I am not sure I understand your question. Windows 3.11 didnt use VBE but it doesnt mean that you cant use it.

Also note its VBE not Vesa, Vesa is the organization that developed the VBE specs.

Hi, as long as the Boot Loader you use has the ability to set the VBE graphics mode, then you will be able to program the graphics code using the C language. You could also set the graphics mode after boot, using a vm86 method.

Thanks for adviding me. Now I know that they aren't the same thing.

I'm going to take a look at vm86. Thanks.

Nathan, if you're developing a real mode OS, you don't need Virtual 8086 Mode at all.
