Thermal Solutions
As processor technology pushes to faster speed and higher performance,
thermal management becomes increasingly crucial to computer systems.
Maintaining the proper thermal environment is the key to reliable, long-term
system operation. The overall goal in providing the proper thermal environment is
keeping the processor's temperature below its specified maximum case temperature.
Heatsinks induce improved processor heat dissipation through increased surface
area and concentrated airflow from attached fans. In addition, interface materials
allow
effective transfers of heat from the processor to the heatsink. For optimum heat
transfer,
Intel recommends the use of thermal grease and mounting clips to attach the heatsink
to the processor. When selecting a thermal solution for your system, please refer to
the website below for collection of heatsinks evaluated and recommended by Intel.

Introduction
1-1 Features of motherboard
The BN860T is designed for Intel's 370-pin processors and the memory
size is expandable to 1GB (using 256Mb technology). This motherboard is integrated
VGA, Audio, and PC Health Function with Mini Flex ATX form factor and supports
total solution for today's computer and embedded IA market.
This motherboard is based on VIA Apollo PLE133T chipset (VT8601T and
VT82C686B) ,
whose 133MHz front side bus delivers a clear upgrade path to the future generation
of 133MHz processors and PC-100/PC-133 SDRAM. The BN860T motherboard
offers ULTR A DM A 66/100 (ATA 100) to provide higher data transfer rate to HDD
and to boost the overall system performance.
The BN860T also has an integrated AC'97 2.1 CODEC on board which is fully
competitive with Sound Blaster Pro that gives you the best sound quality and
ompatibility. VIA VT8601T chipset also includes integrated 3D Graphic Acceleration
to provide a lower-cost solution for video display.
With USB control as well as capability of expanding to 4 USB devices,
the BN860T meets future USB demand. Moreover, it has built-in hardware
monitor function which can monitor and protect your computer.
This motherboard provides high performance and meets future specification demand.
It is really a wise choice for your application.
Before using your computer, you had better complete the following steps:
1. Check motherboard jumper setting
2. Install CPU and Fan
3. Install System Memory (DIMM)
4. Install Expansion cards
5. Connect IDE and Floppy cables, Front Panel /Back Panel cable
6. Connect ATX Power cable
7. Power-On and Load Standard Default
8. Reboot
9. Install Operating System
10. Install Driver and Utility
2-2 Checking Motherboard’s Jumper Setting
(1) CMOS RAM Clear (3-pin): JB1
A battery must be used to retain the motherboard configuration in CMOS
RAM short pin1 and pin2 of JB1 to store the CMOS data.
To clear the CMOS, follow the procedure below:
1. Turn off the system and unplug the AC power
2. Remove ATX power cable from ATX power connector
3. Locate JB1 and short pin2 and pin2 for a few seconds
4. Return JB1 to its normal setting by shorting pin1 and pin2
5. Connect ATX power cable back to ATX power connector
Note: Do not clear CMOS unless
1. T r ouble-shooting
2. You forget the password
3. You fail over-clocking system

2-3-2 Install CPU
This motherboard provides a ZIF socket 370.The CPU that comes with the
motherboard
should have a cooling FAN attached to prevent overheating. If this is not the case,
then purchase a correct cooling FAN before you turn on your system.
WARNING!
Be sure that there is sufficient air circulation across the processor's heatsink
and theCPU cooling FAN is working correctly; otherwise, it may cause
overheating and damage the processor and motherboard. You may install
an auxiliary cooling FAN, if necessary.
Before installing a CPU, first of all, turn off your system and remove its cover.
Locate the ZIF socket and open it by pulling the lever sideways up away from
the socket then upward to a 90-degree angle. Insert the CPU with the
correct orientation as shown below.
12
The notched corner should point toward the end of the level.
Because the CPU has a corner pin for two of the four corners, the CPU will
fit only in the orientation as shown.
2-4 Install Memory
This motherboard provides two 168-pin DUAL INLINE MEMORY
MODULES (DIMM) sites for memory expansion from 32MB to 1GB SDRAM.
NOTE!
Make sure the total installed memory size does not exceed 1GB;
otherwise, the system may hang during startup.
13
NOTE!
When you install DIMM module fully into the DIMM socket, the eject tab should be
locked into the DIMM module very firmly and fit into its indention on both sides.
WARNING!
If the SDRAM CLOCK is set at 133MHz, you must use PC133-compliant
DIMMs. When this motherboard operates at 133Mhz, most system will not even
boot if nonPC133-compliant SDRAM modules are used because of
the strict timing issues. If your DIMMs are not PC133-compliant, set the SDRAM
clock at 100MHz to ensure system's stability.
2-5 Expansion Cards
WARNING!
Turn off the power when adding or removing expansion cards or other system
components. Failure to do so may cause severe damage to both your
motherboard and expansion cards.
2-5-1 Procedure For Expansion Card Installation
1. Read the documentation of your expansion card and make any necessary
hardware or software setting, such as jumpers, for your expansion card.
2. Remove the chassis cover and the bracket plate on the slot you intend to use.
3. Align the card with slot and insert the card firmly.
4. Secure the card in the slot with the screen you remove above.
5. Replace the chassis cover.
6. Set up the BIOS if necessary.
7. Install the necessary software driver for your expansion card.
2-5-2 Assign IRQs For Expansion Card
Some expansion cards need an IRQ to operate. Generally, an IRQ must be
exclusively
assigned to one. In a standard design, there are 16 IRQs but most of them are
already in use.
6 14 Floppy Disk Controller
7 * 15 Printer Port (LPT1)
8 3 System CMOS/Real Time Clock
9 * 4 ACPI Mode when enabled
10 * 5 IRQ Holder for PCI Steering
11 * 6 IRQ Holder for PCI Steering
12 * 7 PS/2 Compatible Mouse Port
13 8 Numeric Data Processor
14 * 9 Primary IDE Channel
15 * 10 Secondary IDE Channel
* These IRQs are usually available for ISA or PCI devices.
2-6 Connectors, Headers
2-6-1 Connectors
(1)Power Connector (20-pin block) : ATX1
ATX Power Supply connector. This is a new defined 20-pin connector that
usually comes with ATX case. The ATX Power Supply is allowed to use soft power
on momentary switch that connects from the front panel switch to 2-pin Power
On jumper pole on the motherboard. When the power switch on the back
of the ATX power supply turned on, the full power will not come into the system
board until the front panel switch is momentarily pressed. Press this
switch again will turn off the power to the system board.
(2)PS/2 Mouse & PS/2 Keyboard Connector: J1
If you use a PS/2 mouse, you must purchase an optional PS/2 mouse set
which connects to the 5-pins block and mounts to an open slot on your
chassis.
(3)USB/ LAN Port connector: J2
The connector is a 16-pin connector that connects USB/LAN devices to
the system board.
(4)Parallel Port Connector (25-pin female):J4
