stepper motor configuration

I'm doing a project using AT89C51. I need to use stepper motor which can move in both direction and can carry a weight around 100g. Can any one plz send me its configuration?

Please don't post more then one topic. It won't help get more responses, it just makes things confusing.

I posted a reply under your other topic. Be patient and research as much as you can on your own and post back with questions.
