Clear seperation between hardware/OS

My All in ONe book kinda meshes everything together. Where is that clear line in what they test? Are both tests able to test on all material?
For instance. I/O address's is that os or hardware? same with DMA, IRQ's.
I know OS only things will be in OS, and vice versa, but there are a few things that mesh into each other.

Thanks

They will test you on anything listed in the objectives of each test. http://comptia.org/certification/A/objectives.asp Meaning that the OS test will only test you on the objectives of the OS and the hardware will only test you on the objectives of the hardware.

one of the books i used was the original examcram book and it kind of mixed both together too.

once you read through your book and get to the point where you feel like trying a few practise tests, you will see the line a little more defined
