can anyone help me ? I have one hd + cdr on one ide belt. I want to add cdrw. I purchased another ide belt but i dont know where excactly to connect it on the motherboard (there are already 2 used connections: one for the floppy drives and one for the hd + cdr). Is it writen on the motherboard which is "primary", "secondar", "slave", "master" ? The truth is i dont excactly know what these terms mean. Can any one explain it to me ? what: "master", "primary", "secondary", "slave" mean and how i identify it ? I need that to know how to put the jumper on the disc. Thanks a lot.
