2.14 IDE Connector (CN2)
The PCA-6780 provides one IDE channels to which you can attach up to
two Enhanced Integrated Device Electronics hard disk drives or CDROM
to the PCA-6780’s internal controller. The PCA-6780's IDE controller
uses a PCI interface. This advanced IDE controller supports faster data
transfer, PIO Mode 3 or Mode 4, UDMA 33/66/100 mode.
2.14.1 Connecting the hard drive
Connecting drives is done in a daisy-chain fashion. It requires one of two
cables (not included in this package), depending on the drive size. 1.8"
and 2.5" drives need a 1 x 44-pin to 2 x 44-pin flat-cable connector. 3.5"
drives use a 1 x 44-pin to 2 x 40-pin connector.
Wire number 1 on the cable is red or blue, and the other wires are gray.
1. Connect one end of the cable to CN2. Make sure that the red (or
blue) wire corresponds to pin 1 on the connector, which is labeled
on the board (on the right side).
2. Plug the other end of the cable into 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 con-
nector.)
If desired, connect a second drive as described above.
Unlike floppy drives, IDE hard drives can connect to either end of the
cable. If you install two drives, you will need to set one as the master and
one as the slave by using jumpers on the drives. If you install only one
drive, set it as the master.
