I am going to start an OS level project. I would be glad if somebody help me where to start,which way to proceed
Should I write the kernel first or what is the minimum req. of a std kernel which can access hard disk,keyboard and CUI display?????????

Don't worry about hard drive access first. Just make a simple booting kernel that says "Hello World" or something on the screen.

You should have read the other 'getting started' posts on here.

And look at the Wiki!!! It has everything you need to get started! http://www.osdev.org/wiki/

And google is you friend.
