1.4. Collect Compatible Hardware 

Compatible hardware means a set of hardware, members of which set can work together. For example, an IDE hard disk and a motherboard is compatible they can be connected by a cable and work together. So, to install a hard disk we at first need a set of compatible hardware. For an IDE hard disk, we need: 

 The IDE hard disk itself 

 Motherboard or I/O card that supports IDE interface 

 IDE interface cable For a SCSI hard disk, we need: 

 The SCSI hard disk itself 

 SCSI host adapter card 

 Motherboard that supports SCSI interface 

 SCSI interface cable 

1.5. Jumper Settings 

1.5.1. Primary and Secondary 

Normally a motherboard with IDE interface supports at most four hard drives. It supports 2 IDE interface cables and each cable supports 2 drives. The 1st cable of the 2 is called the primary and the 2nd is called the secondary. Similarly the 2 hard drives connected with the 1st cable are called primary hard drives and the other 2 connected with the 2nd cable are called secondary. How the motherboard knows which is the primary cable and which is the secondary? There are 2 IDE slots on the motherboard. One is numbered as IDE1 and the another is numbered as IDE2. The cable and the 2 hard drives connected with the IDE1 slot are called the primary cable and hard drives. Similarly the cable and the 2 hard drives connected with the IDE2 slot are called the secondary cable and hard drives.
