Determine Your Existing IDE Configuration

With your computer open, determine the existing IDE configuration.
You can do this by looking at the IDE ribbon cable (or cables—there
may be two) and seeing what is connected to them.
One end of the IDE cable connects to the IDE port on your computer's
motherboard; and there are usually two other connectors for attaching
peripheral devices such as a hard disk, DVD or CD-ROM drive, or your
PX-750A drive. If there are two devices, one is configured as Master
and the other the Slave, as indicated by the position of jumpers on the
back of the drive.
If your computer is set up for Cable Select, or CSEL, both devices will
be jumpered as Cable Select. In older computers, this configuration
required a special Cable Select cable.
If there are two IDE cables, one is for the primary IDE bus and the other
is for the secondary bus.
