The mainboard uses the highly integrated Apollo MVP4. The Apollo MVP4
is a PC Socket-7 system logic North Bridge with integrated 2D/3D Graphics
Accelerator. The core logic portion of the chip is based on the popular
100MHz VIA Apollo MVP3 chipset with enhanced features and graphics
accelerator based on the Cyber9398DVD from Trident Microsystems. The
VT82C686ASuperI/O PCI integrated Peripheral Controller (PSIPC) is ahigh
integration, high performance, power efficient and high compatibility device
that supports Intel and non-Intel based processors plus PCI bus bridge
functionality to make a complete Microsoft PC98-compliant PCI/ISA system.
The VT82C686A supports PCI-to-ISA bus controller, four USB ports, dual
bus-masterIDE with Ultra DMA33/66, AC97Basic Audio, System Hardware
Monitoring, and integrated “Super I/O functionality”.
This Mainboard with Apollo MVP4 coupled with VT82C686A is a ideal
performance energy efficient, and highly integrated computer systems.

Hardware Installation
2.1 Central Processing Unit: CPU
The MicroATX VI16 mainboardoperates with Intel®Pentium®processor/
Pentium® processorw/MMXTM technology, Cyrix®/IBM6x86/6x86L/
6x86MX/MII,andAMD®K6/K6-2/K6-III processors. Itcouldoperatewith
2.2V to 3.2V processors. The mainboard provides a 321-pin ZIF Socket 7 for
easy CPU installation. The CPU should always have a cooling fan attached
to prevent overheating.

1. Pull the lever sideways away
from the socket. Then raise
the lever up to a 90-degree
angle.
3. Press the lever down to
complete the installation.
2. Locate Pin 1 in the socket
and look for the white dot or
cut edge in the CPU. Match
Pin 1 with the white dot/cut
edge. Then, insert the CPU.
It should insert easily.

2.1-2 CPU Core Speed Derivation Procedure
1. The DIP Switch SW1 (1, 2, and 3) are used to set the Core/Bus
(Fraction) ratio of the CPU. The actual core speed of the CPU is
the Host Clock Frequency multiplied by the Core/Bus ratio. For
example:
If CPUClock = 66MHz
Core/Bus ratio = 3.5
then CPU core speed = Host Clock x Core/Busratio
= 66MHzx3.5
= 233MHz

2.1-4 Fan Power Connectors: CFAN1/SFAN1
These connectors 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 has System Hardware Monitor chipset on-board, you must use a
specially designed fan with speed sensor to take advantage of this function.
For fans with fan speed sensor, every rotation of the fan will send out 2
pulses. System Hardware Monitor will count and report the fan rotation
speed.
Note: 1. Always consult vendor for proper CPU cooling fan.
2. CPU FAN supports the FAN control. You can install PC Alert
utility. This will automatically control the CPU FAN Speed according
to the actual CPU temperature.

To adjust the speed and voltage of the CPU, you must know the
specifications of your CPU (always ask the vendor for CPU specifi-
cations). Then refer toTable 2.1 (Intel®processors),Table2.2
(Cyrix®processors)and Table 2.3 (AMD®processors) forproper
setting.

Table 2.2 Cyrix®processors
Cyrix®6x86 processor uses PR to rate the speed of their processors based
on Intel®Pentium®processor core speed. For example PR150 (120MHz) has
150MHz core speed of Intel®Pentium®processor but has 120MHz core
speed in Cyrix®. Cyrix®6x86 processor should always use a more powerful
fan (ask vendor for proper cooling fan).
