2.16-5 Power/System Fan Connector: PSFAN/SFAN
This connector support system cooling fan with +12V. It supports three pin
head connector. When connecting the wire to the connector, always 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 your
mainboard had a System Hardware Monitor chipset on-board, you must use
a specially designed fan with speed sensor to take advantage of the power
and system fan control.

Note: For fans with speed sensor, every rotation of the fan will send out 2
pulses. System Hardware monitor will count and report the fan
rotation speed.

2.16-6 CD-ROM Power/Audio In Connector: J14
This connector is connected to the MS5943 CDIN. The MS5943 should be
connected at the back of the CD-ROM. The MS5943 contains an IDE
connector and a CDIN connector.
2.16-7 Hard Disk Connectors: IDE1 & IDE2
The mainboard has a 32-bit Enhanced PCI IDE Controller that provides PIO
mode 0~4, Bus Master, and Ultra DMA/33 function. It has two HDD connec-
tors IDE1 (primary) and IDE2 (secondary). You can connect up to four hard
disk drives, CD-ROM, 120MB Floppy (reserved for future BIOS) and other
devices to IDE1 and IDE2. These connectors support the provided IDE
hard disk cable.
IDE1(Primary IDE Connector)
The first hard drive should always be connected to IDE1. IDE1 can
connect a Master and a Slave drive. You must configure second hard
drive to Slave mode by setting the jumper accordingly.
IDE2(Secondary IDE Connector)
IDE2 can also connect a Master and a Slave drive.
