I am attempting to reformat a computer that has two drives -- the original 4 gb that came with the computer and another 15 gb drive that was installed later. I want to make the 15 gb drive my master and the 4 gb drive the slave but I can't figure out the order and way I need to go about reformating so that I can install my OS on the 15 gb. Win98 is currently on the 4gb drive. If I clean off the 15 gb using fdisk, can I then direct an fdisk on the 4gb? Would I then make the physical switch on the pins for each drive so the master becomes the slave and vice versa and then be able to install Win98 on the larger drive? What would I have to do to the smaller drive? Does it have to have a Fat32 partition or something? This is new territory for me. Thanks in advance for your help.
