What are the differences between master/slave and cable select ?
A5: Two different protocols can be used for jumpering ATA devices, including hard disk drives. One is the master-slave relationship. With this protocol, one device is jumpered as master and the other is jumpered as slave. The second protocol is cable select. With this protocol, both devices are jumpered as cable select and their position on the cable dictates which is the master and which is the slave. The end device is master while the device on the middle of the cable is slave. You can use either of these protocols but you cannot mix them on the same data cable. Computers that use cable-select determine the master and slave drives by selecting or deselecting pin 28, CSEL, on the interface bus. Master and slave drives are determined by their physical position on the cable. Configuration Using Cable Select Cable Select is defined in the ATA-2 and ATA-3 specifications and is part of the ATA PnP standard and Microsoft’s PC97 standard.
