read some book on os developing first

As well as that please, please read this:

http://www.catb.org/~esr/faqs/smart-questions.html

It seems the bulk of your questions can be answered RTFM or STFW. Also here's a new one (I just thought of ) RTFFAQ. The osdev faq is at:

www.mega-tokyo.com/osfaq2

Another place I'd recommend you going to is the Operating System Resource Center, lots of info there.

Also get some good books, osdev is about 50% reading IMHO.

Hope this helps

start by a very simple kernel, compile it and load it in your bootsector

as saied above.. start with a very simple kernel, like writing hello on the screen. after that u could expand that into a text mode driver by writing functions for string output, moving the cursor and setting colors..
then a suppose that user input via the keyboard would be a nice idea..

(may sound like a shell, but in the beginging it?s just to test future drivers/ints..)

after that.. well...
