Introduction

The AZZA U601 Mainboard Series Page 9
The mainboard is capable of monitoring the following health conditions of your
system:
1. Processor temperature. It has an overheat alarm.
2. VCORE/2.5V/3.3V/5V/12V voltages and failure alarm.
3. Processor and chassis fan speeds. It has a failure alarm for these fans.
4. Read back capability that displays temperature, voltage and fan speed.
Note: Only use this utility in Windows ® 95 or Windows ® 98 operating systems.
1.4.1. Hardware Monitoring System Utility
The mainboard comes with the Hardware Monitoring System utility contained
on the CD. It is capable of monitoring the system’s hardware conditions such
as the temperature of the processor, voltage, and the speed of both the CPU
and chassis fans. You are allowed to manually set a range to the items being
monitored. If the values are over or under the set range a warning message
will automatically pop up. We recommend that you use the Default Settings,
which are the ideal settings that will maintain the system in a good working
condition.
1.4.2. Installation
To install this utility, please insert the CD into the CD-ROM drive. The auto run
screen (Driver Utility) will automatically appear. Click the Hardware Monitoring
button, choose the chipset, model number and the OS that is installed. Please
refer to the CD “Readme” file for further installation instructions.

You need to complete the following installation steps before you can use your PC.
!Check and Set the Mainboard Settings.
!Install the Central Processing Unit (CPU).
!Install the Memory Modules.
!Install the Expansion Cards.
!Connect the Ribbon Cables, Panel Wires and the Power Supply.
!Setup the system BIOS
Before you start installing your mainboard we strongly recommend
that you use a grounded anti-static mat. We further recommend
that you attach an anti-static wristband, which is grounded at the
same location as the mat, to your wrist.

2.4.1. Installation of the CPU
To install your processor, please complete the following set of instructions
1. Locate a small dot marked on the top of the CPU. This mark indicates
Pin 1 of the CPU.
2. Locate Pin 1 (Alignment Notch) the Socket on the mainboard.
3. There is a lever on the side of the socket. First push this lever side-
ways and then lift it to a 90-degree angle.
4. Insert the CPU into the Socket. Please make sure that Pin 1 for the
CPU is inserted into Pin 1 of the Socket.
5. When the CPU is installed correctly push the lever back into place.
6. Install a proper heat sink with cooling fan for proper heat dissi-
pation. Failing to install a heat sink with cooling fan may cause over-
heating which will burnout your CPU and damage your mainboard.
IMPORTANT: CPU COOLING FAN
Please ensure that you have an approved heat sink with cooling fan.
Without a proper heat sink with cooling fan you will damage both the
mainboard and the CPU.
2.4.2. Memory Modules
The U601 mainboards have two 168-pin DIMM slots and are able to support a
maximum of 1GB PC-100/PC-133 SDR SDRAM. The DIMM slots are located on
the right hand side of the board. To install the DIMM’s into these slots, make
sure the white lever at each side of the slot has been pulled down to an angle
of approximately 45°. Make sure that the DIMM is in the correct orientation.
Place the DIMM on the slot and push down firmly.The white levers will come
back up and lock the module in place (diagram on next page).
Important: The DIMM’s can only be fitted into the slots in one orien-
tation. Make sure that the DIMM’s are in the correct orientation and
the pins are correctly aligned before you insert them.

2.4.3. PCI Slots
The U601 mainboards come with two
PCI slots. They are located on the left
hand side of the board. Both PCI and
PCI expansion cards may require IRQ’s.
This mainboard complies with Plug and
Play (PnP) specifications. Whenever a
PnP compliant card is added the system
will automatically be configured and the
IRQ’s will be assigned automatically.
When you are inserting your PCI card
make sure that the pins are correctly
aligned. When the pins are properly
aligned with the hole’s in the slot, push
down gently.

NOTE: “Out Of Memory” Error Message
If you have installed more than 512 MB of RAM and are running Microsoft Windows
Millennium Edition, Windows 98 Second Edition, Windows 98 or Windows 95 you
may experience memory problems. Two symptoms of these problems are being
unable to run an MS-DOS session while you are running Windows or the computer
may stop responding while Windows is starting.
There are three possible solutions to this problem:
1) Reduce the amount of memory Vcache uses to 512 MB or less by altering the
MaxFileCache setting in the System.ini file.
2) Use the System Configuration Utility to reduce the amount of memory Win-
dows uses to 512 MB or less.
3) Reduce the memory installed on your computer to 512 MB or less.
This problem can also occur if you are using an Advanced Graphic Port (AGP)
video adapter.

The U601 mainboard has two IDE connectors: a primary and secondary. Each
IDE connector can support two IDE drives. These mainboards can therefore
support up to four IDE devices each. If you install two hard drives, you need to
configure the second drive to slave mode in the BIOS setup. Please refer to
your hard drive manual for the appropriate jumper settings.

2.5.7. USB 3 and USB 4 Connectors
Connector: CN 30 (USB 3)/CN 31 (USB 4)
Type: 5 pin / 5 pin
You already have two USB ports available, USB 1 and 2 (see external connec-
tors). The internal USB connectors allow you to add on an optional kit to ex-
pand the total number of USB ports available. The U601 mainboards have two
internal USB connectors (CN30 and CN31). This enables you to use an extra
two USB devices. Cable for these additional connectors needs to be purchased
separately.
2.5.6. CD Audio-in Connector
Connector: CN 21
Type: 4 pin un-housed
This mainboard has one CD Audio-in connectors. This connector is used to
connect the CD ROM audio out.
2.5.5. WOL Connector
Connector: CN 16 (WOL)
Type: 3 pin
The Wake-On-LAN (WOL) connector
must be connected to a LAN card that
has Wake-On-LAN output. This con-
nector powers up the system when a
wakeup packet or signal is received
through the LAN card.
In order to use the WOL LAN card or the modem to trigger the power on the
PC system, the switching power supply must have the ability to provide a driv-
ing current of at least 720 mA and be connected to a “5V standby” voltage.
