Hardware Setup
Audio Port Connectors (Optional)
Depending on the mainboards you purchase, there are two options for
the audio ports: three-port audio connectors for 865G Neo2-P / 865PE Neo2-
P Option 1 and six-port plus SPDIF-Out for 865PE Neo2-P Option2.
Line Out is a connector for Speakers or Headphones. Line In is used
for external CD player, Tape player, or other audio devices. Mic is a connector
for microphones. SPDIF-out is a jack for coaxial fiber connection for digital
audio transmission.
For 865G Neo2-P / 865PE Neo2-P Option 1
For 865PE Neo2-P Option 2, there are six ports plus the SPDIF-Out for
6-channel and S/PDIF function. For more information on 6-channel audio
operation, please refer to Appendix A: Using 2-, 4- & 6-Channel Audio

Hardware Setup
The mainboard provides connectors to connect to FDD, IDE HDD, case,
LAN, USB Ports, IR module and CPU/System/Power Supply FAN.
Floppy Disk Drive Connector: FDD1
The mainboard provides a standard floppy disk drive connector that
supports 360K, 720K, 1.2M, 1.44M and 2.88M floppy disk types.
Connectors
FDD1
Fan Power Connectors: CPUFAN1/SFAN1, SFAN2/NBFAN1
The CPUFAN1 (processor fan), SFAN1/SFAN2 (system fan) and NBFAN1
(NorthBridge Chipset fan) support system cooling fan with +12V. It supports
three-pin head connector. When connecting the wire to the connectors, al-
ways take note that the red wire is the positive and should be connected to the
+12V, the black wire is Ground and should be connected to GND. If the
mainboard has a System Hardware Monitor chipset on-board, you must use a
specially designed fan with speed sensor to take advantage of the CPU fan
control.
MSI Reminds You...
1. Always consult the vendors for proper CPU cooling fan.
2. CPUFAN1 supports the fan control. You can install Core
Center utility that will automatically control the CPU fan speed
according to the actual CPU temperature.
