Aaeon PCM-4894 User Manual page 24

You can attach two Enhanced Integrated Device Electronics hard
disk drives to the PCM-4894's internal controller. The card
comes with a 40-pin flat piggyback cable. This cable has one 44-
pin 2.0mm pitch and two identical 40-pin flat-cable connectors.
Usually, wire number 1 on the cable is red or blue, and the other
wires are gray.
1. Connect one end of the cable to the IDE connector. Make
sure that the red (or blue) wire corresponds to pin 1 on the
connector, which is labeled on the board.
2. Plug the other end of the cable to the Enhanced IDE hard
drive, with pin 1 on the cable corresponding to pin 1 on the
hard drive. (See your hard drive's documentation for the
location of the connector.)
Unlike floppy drives, you can make the connections with any of
the connectors on the cable. If you install two drives, you will
need to set one as the master and one as the slave. You do this
using jumpers on the drives. If you install just one drive, set it as
the master.
