PCM-9586 User’s Manual 16
2.7 IDE, CDROM hard drive connector (CN5, CN6)
The PCM-9586 provides 2 IDE channels which you can attach up to four
Enhanced Integrated Device Electronics hard disk drives or CDROM to
the PCM-9586’s internal controller. The PCM-9586's IDE controller uses
a PCI interface. This advanced IDE controller supports faster data trans-
fer, PIO mode 3, mode 4 and UDMA/100. The secondary channel sup-
ports UDMA/33 only.
2.7.1 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 CN5, CN6. 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.
2.8 Solid State Disk
The PCM-9586 provides a CompactFlash™ card socket and DiskOnChip
socket for Solid state disk solutions.
2.8.1 CompactFlash (CN20)
The CompactFlash card shares a secondary IDE channel which can be
enabled/disabled via the BIOS settings.
