Or you could code a OS based on a games console OS like mine, there's not many of these. But this does not mean it need to be for running games, it just means its make to run a single program, without any other program getting it its way.
It could just as easy be for playing music or controlling robots etc.

Have fun porting stuff - who wants to reinvent the wheel anyway?

Anyone developing a new operating system is essentially already doing this.

I agree. Copy-and-paste OSes are nothing (in my opinion) to be proud of.

There is a problem with this statement. An OS is alot more then one peice of software. If almost all of the software was simply copied+paste, then I would need to agree with the above statement.

However, this assumes that the system was developed "from scratch" as a new OS. If it was being developed as a derivative of an existing OS, that is a different story as the above statement does not apply. (ie, it is being developed as an upgrade, a newer version, or it can also be different software based off of the existing OS.)

JamesM and 01000101: Please cool down. There is no reason to attack some one else just because they post their opinions.

Remember that there is a difference between "copy+paste" and "using existing software or libraries".

copy+paste implies that the developer copied and pasted code claiming that they were the original developer for the code, and not giving any credit, or may not even be understanding it.

using existing software (ie GRUB) or external libraries are fine. While it still does not mean it was "written" from scratch, the software is being used under a legit license. This is fine.

copy+paste implies that the developer copied and pasted code claiming that they were the original developer for the code, and not giving any credit, or may not even be understanding it.

the end of your statement was exactly what I was trying to say. Using other people's code without really understanding it and having put no effort into actually 'making' the OS has no pride in it.

I appologize for the miscommunication.

i don't agree, IMHO, there is no difference, even if there is difference, we couldn't identify itself unless we meet them and talk about this.

if they started "copy+paste", sooner or later they will understand it.

BTW, we are all using c/c++ compiler/syntax/mechanism/libraries.
there is no new thing about it.

Not all.

That's what I'm going to do then, except I'm going to write it in C, and have elf executables, and a make of port a C library.
EDIT: Do I need to use the IDT if I am not using the timer int. Do I need the keyboard int to use the keyboard?

You can turn them off (eg: cli in realmode before going to pmode )and poll for key input, but i would not. And the time is used a lot by games.
