INSTALLATION
Host Interface Connections
Most current mainboard models have two IDE ports (primary and
secondary), which can connect two IDE cables. Two IDE cables
allow you to connect up to four devices, but it is recommended that
you separate IDE ports for your hard drive and your DVD-ROM drive.
If you connect only one device on the IDE cable, you can set the
jumper as “master” or “slave”.
If you connect two devices (e.g. DVD-ROM & CD-RW) on the same
cable, set different jumpers for each device (DVD-ROM as “master”,
CD-RW as “slave”, and vice versa.) The same rule applies to the
connection of having your hard disk and another device on the same
cable.
