DMA and I/O

What are the Main I/O addresses we need to know for the Core hardware?

Do we just need to know Starting address or whole range?

Im trying to make a review sheet for, IRQ's, I/O's and DMA's

where it would be like this.

IRQ0 = System Timer

DMA4 = DMA Controller.

You should also know the I/O's for the primary and secondary IDE controllers and LPT1 as well as LPT2. I spent a lot of time memorizing most of them and didn’t get any questions on them, but that doesn’t mean you wont. I also only got maybe 3 IRQ questions and there were all about COM ports.
