I was wondering...

i've heared that If i'm writing an operating system in C++ i cannot use any DOS interrupt/command.

So i'm asking:
What commands/interrupt can i use?

Just wondering...

If you are writing an operating system you can't use the facilities of another otherwise that operating system would have to be running for yours to work which rather defeats the object of writing an operating system.

The only software interrupts that are available to you are the those that you write yourself.
