Mouse problems....

How would you write a mouse driver?

Do you know where I could find any tutorials, books, or source code?

I only found one thing relavant to my question, and it says that IRQ 12 (interrupt 74h) is called by the mouse

hardware after each movement, button press, etc... I wrote a ISR to intercept IRQ 12, whipped-up some code to

modify the vector table, and it was never called by the mouse. Am I forgetting something? Is there a bit-flag in

some port that I need to modify?
