Ide Interface; Table 4-8: Ide Hard Drive Connector - Advantech HMI-640S User Manual

4.9.2 IDE interface

Users can attach two IDE devices to the IDE channel, one drive
must be set as the master and another as the slave. You may do this
by setting the jumpers on the drives. Refer to the documentation
that came with your drive for more information.
A jumper diagram usually appears on the top side of a hard disk
drive.
