2.5.14 Audio connector (CN17)
The PCI-6870 CPU card supports AC97 with the help of an
optional cable connected to CN17. The optional audio cable is P/N
1700160160.
2.5.15 Secondary EIDE connector (CN18)
The secondary channel supports UDMA/33 only.
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 flatcable
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.
Connect one end of the cable to CN18. 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).
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 connector.)
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.
2.5.16 Floppy Drive Connector (CN20)
You can attach up to two floppy disk drives to the PCI-6870's onboard
controller. You can use any combination of 5.25" (360 KB/1.2 MB) and/
or 3.5" (720 KB/1.44/2.88 MB) drives.
The card uses a Hirose 20 connector (DF13-20DP-1.25V).
2.5.17 CompactFlash Disk (SK1)
TM
The PCI-6870 is equipped with a CompactFlash
disk socket on
the solder side that supports the IDE interface for CompactFlash
cards. The on-board CompactFlash socket is designed to prevent
incorrect installation. Be sure that the system power is off when
