CS (CSEL)
If you choose the CS setting, the Master/Slave setting will be made automatically depending
on your hardware configuration.
Connect to Primary/Secondary IDE Port
In most of the PC systems, the hard disk drive is always as a Master device and connected to
Primary IDE port to boot the operating system. Besides this hard disk drive, if you need to
connect DVD-ROM to the Primary IDE port, DVD-ROM must be a Slave device.
If there are two devices currently connected to the Primary IDE port, you may connect DVD-
ROM drive to Secondary IDE port. In this configuration, the DVD-ROM drive is as Master
device if there is no other device connected to Secondary IDE port. Otherwise, the DVD-ROM
drive should be as Slave device if master device existed.
Figure 3 shows where the DVD-ROM can be connected.
