Hello All,
Well, I am planning on making an operating system and it'll be a long jump but still...I have the hardware but the other levels are problems. Here:
Applications
I/O Management
Device Drivers
Memory Management
CPU Management
Hardware
I'm now focusing on the Device Drivers section. I need to now some code snippets, structure, and anything else on Device Drivers.
Any other info would be helpful.
Thanks.

Eh...device drivers for what? Mouse, keyboard, hard drive... They're very different.

You know when you got a character to print to the screen? That was basically a device driver.
Most of the basic stuff is just a matter of finding out where what needs to go and in what order, or which port to put data in and pull data out of or which flags need to be checked and where they are.
You could start with just a generic keyboard driver and I'm certain you can find examples, if not just look at the linux .01 kernel source.

These are relatively straightforward
Keyboard controller specifications
Mouse controller specifications (You need to scroll down nearly halfway to get to the actual port specifications. You should skim the material before it, though.)
Kung fu.
Parallel port I/O specifications
