Making ISO self boot...

hi, i know this is a vague question and everything. but how do i go about making an ISO into a self boot cd? i have some zips and shit to help me, but i am confused about them. one takes me through this whole processes w/ dummy files and shit and makes me use CDRWIN and this other is just an exe called DC Self Boot Took Kit 3.4 please give me some info on going about this, thanx
