Question

I am looking at some existing real-mode code that uses the in and out assembly instruction.

I recognize a few, but I don't know what most of the different ports in the instructions are related to.

Is there a list of what the different I/O ports refer to?

Was it helpful?

Solution

You can find a list here, for x86.
