Now my OS simple prints the little welcome message. Gets how much memory my PC has, and displays that.

But any way I whant to beable to get input from the keyboard. How do I do that?

Install a handler on IRQ 1. When you receive an IRQ 1, read a scancode from port 0x60.

Whats all this about ports?

Too much to explain here. You should read some tutorials. See the QuickLinkz topic.
