Here´s the deal. I bought a computer in last autumn. It has two hard disks. The master disk broke a couple a weeks ago. Yesterday I got a new one (warranty). Its an IDE disk. My problem is which "bus" setting shall I use. I have thrown away al my "how to build your own computer" papers. There are three alternatives: 1: Slave 2: Single or master 3: Master w/ slave present obviously it isn´t the first one. Whats the difference between number 1 and 2. And just to make sure It´s the MASTER disk I´m talking about.
