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.
2.15  VGA/LCD  interface connections
The PCI-6872’s display interface can drive conventional CRT displays 
and is capable of driving a wide range of flat panel displays as well, 
including passive LCD and active LCD displays. The board has two dis-
play connectors: one for standard CRT VGA monitors,  and one for flat 
panel displays.
2.15.1 CRT display connector (CN7)
CN7 is a standard 15-pin D-SUB connector commonly used for VGA.
Pin assignments for CRT display connector CN7 are detailed in Appendix 
C
2.15.2 Flat panel display connector (CN22)
CN22 consists of a 40-pin connector which can support an 18-bit LCD 
panel. It is Hirose’s product no. DF13A-40DP-1.25 V.
The PCI-6872 provides a bias control signal on CN22 that can be used to 
control the LCD bias voltage. It is recommended that the LCD bias volt-
age not be applied to the panel until the logic supply voltage (+5 V or 
+3.3 V) and panel video signals are stable. Under normal operation, the 
control signal (ENAVEE) is active high. When the PCI-6872’s power is 
applied, the control signal is low until just after the relevant flat panel sig-
nals are present. CN22 can connect up to 18 bit TFT LCD
.
2.15.3  Extension flat panel connector(CN23)
CN23 consists of a 20-pin connector which is Hirose's product no. DF13-
20DP-1.25V. The PCI-6872 supports a 36-bit LCD panel which must be 
connected to both the CN22(40-pin) and CN23 (20-pin). The pin assign-
ments for both CN22 and CN23 can be found in Appendix C.
2.15.4  LVDS LCD panel connector (CN25)
