Drive Connectors
There are three drive connectors on the motherboard for
connecting IDE and floppy disk drives.
IDE Drive Connectors
Function: The two IDE connectors, marked ‘Primary’ and
‘Secondary’, are for connecting IDE drives to the
motherboard.
Description: The IDE controller on the motherboard sup-
ports IDE devices running in all modes up through ATA-
100. There are two IDE drive connectors. Each connector supports two drives, a ‘Master’ and a ‘Slave’ which
connect to the motherboard with a ribbon cable. The
supplied cable supports transfer modes through ATA-100.
More Information: See the section on “Connecting In-
ternal Peripherals” in Chapter 5 for instructions on connecting IDE drives. Technical specifications are listed in
Chapter 7.

Floppy Drive Connector
Primary
Floppy Disk Drive Connector
Function: The floppy disk drive connector, marked
‘Floppy’, is for connecting one floppy disk drive to the
motherboard.
Description: The floppy disk drive connector supports
connecting one floppy disk drive to the motherboard.
The ‘Floppy’ drive connector uses a standard FDD rib-
bon cable. The floppy disk drive connected to the end of
the cable will function as Drive A:. A second drive can
be added as Drive B: if required.

2: Key Features & Components
The system fans use the motherboard fan speed control,
which consists of three states: Off, Normal speed, and
High speed. In Normal speed mode, the system fans run
at normal speed until the thermal sensor senses the temperature exceeds the High speed fan threshold temperature. The system fans then run at High speed when the
temperature threshold is exceeded. You can set the fan
threshold temperature in the PC Health section of the
CMOS Setup Utility. You can set the threshold to 40°C to
force continuous operation of the system fans in highspeed mode in the S0 and S1 sleep states.
More Information: Please see the PC Health Status section of “Configuring the CMOS Setup Utility” in Chapter
5 for information.
Cooling Fan Connectors:
The cooling fan power
connectors all use the

Fan connector is not.
WOL: Wake On LAN Connector J75
Function: A connector for the lead from a Network Interface Card that supports the Wake On LAN feature.
Description: This feature enables the system to “wake
up” from Suspend mode when it receives a signal over a
LAN it is connected to. It works with the optional onboard
LAN port and will also work with an additional PCI NIC
that supports this feature by connecting the card to the
WOL connector on the motherboard.
The motherboard supports Wake on LAN through the
PCI bus PME# signal and the onboard Intel 82550 LAN
controller. This signal will wake up the computer only
when it is plugged into an AC power source and the system is in a supported sleep state.
More Information: Please see the Power Management
Setup section of “Configuring the CMOS Setup Utility”

Chassis Intrusion Switch Connector JP12
Function: Connector for Chassis intrusion switch.
Description: The hardware monitor subsystem supports
a chassis security feature that detects if the chassis (system housing) cover is removed. When the cover is removed, a signal is sent to the hardware monitor component. The chassis intrusion circuit is powered by the system power supply when the computer is connected to
AC power or by the onboard battery when it is not.
This feature uses a mechanical switch on the chassis that
connects to the chassis intrusion connector on the
motherboard. When the chassis cover is removed the
motherboard circuitry will detect the intrusion.
More Information: See the “System Features” section in
Chapter 6.
