The mainboard comes with
one IDE cable. If you install
devices on the second IDE
channel with another cable,
it may not have the orienta-
tion extrusion on the side of
the cable connector, which
prevents attaching the cable
incorrectly. Please check the

Component Information
This section is a brief description of the components on the
mainboard that you might need to know about if you want to
upgrade or change your system configuration. If your mainboard
is already installed in a system, it isn’t necessary for you to re-
view this section.
This mainboard uses the ATX ‘form factor’, a design that inte-
grates many features onto the board including some number of
external ports.
Expansion Cards & Slots
The mainboard has seven expansion slots for system expan-
sion or ‘add-on’ cards. Three of them are ISA slots, the other four
arePCI slots.When youget anexpansion card,it mustuseone of
these to connect to the computer.
The ISA expansion slots are a legacy of the original IBM PC/
AT design.Theyare 16-bitslotsthat runat amoderatebus speed.
There are many kinds of expansion cards that use this slot design
to connect to the computer, some of the most common being
sound and modem cards.
PCI slots are the current high-speed 32-bit standard for sys-
tem expansion cards. They operate at a faster speed and have a
greater data throughput than ISA cards.
Expansion cards often make use of system resources, which
requiresmanagingthesystemresourceconfiguration.Mostnewer
expansion cards support the ‘Plug and Play’ standard that allows
an Operating System like Windows95 to automatically detect
them and configure system resources as needed. Some older ISA
designs may not support this standard and may therefore require
manual configuration. You should consult the specifications or
documentationfor acard todetermine ifthis isthe caseand what
needs do be done to properly configure the card.

Memory Sockets & Modules
There are three memory module sockets on the mainboard.
They use 168-pin DIMM memory modules. The sockets func-
tionindependently ofeach other. Thismainboard hasa veryflex-
ible memory design that allows the use of a variety of memory
options up to a total of 256MB. There is more information about
thisinAddingSystemMemorysectionofSection3:Reconfiguring
Your Mainboard.
CPU Socket & CPU
The Socket 7 CPU socket supports the full range of Pentium®-
class CPUs including MMX Pentiums®. Installing a CPU in the
socket is easy. The lever at the side of the socket latches the CPU
in place when it is down and releases it when raised.
If you want to install a CPU upgrade or are installing a CPU
on the board for the first time, please refer to ‘Installing a CPU’ in
Section 3: Reconfiguring Your Mainboard.
Port & Controller Connections
This mainboard has two external Serial ports, a Parallel port,
two USB (Universal Serial Bus) ports and both a PS/2-type key-
board and mouse port built onto the board. There are also sev-
eral connectors built onto the board. There are connectors for
fourIDEdevicesin two‘channels’andfortwo floppydiskdrives.
There are also connectors on the board for some system case
features, CPU and other cooling fans and some other hardware
features.
Details about these connectors are in Section 4: Reference In-
formation.

Using Your Mainboard
This section covers the following topics:
• System Controls & Indicators
• Hardware Features
• Firmware & Software
Theygo over thesystem control featuresand status indicators
that derive from the mainboard and explain the software that
comes with or is built-into the mainboard
System Controls
There are two topics in this section, a explanation of the hard-
ware controls and status indicators that connect from the main-
board to your system case and some information about the parts
of the CMOS Setup Utility that allow you customize some sys-
tem features.
Hardware Controls & Indicators
Therearesomecontrol featuresandstatusindicators thatcon-
nect from the mainboard to your system case, which is some-
times called the ‘Enclosure’ or ‘Chassis.’ These are:
• Power Switch
• Power Status Indicator
• Suspend Switch
• Suspend Status Indicator
• Reset Switch
• Hard Disk Drive Activity Indicator
• Keyboard Lock
All of these case features connect to the mainboard via con-
nector strip J10. Not all system cases have all of these features, so
your system may not have all of them. The functions and op-
tions for these are shown in the table on the next page.

CMOS Setup Utility Controls
Two sections of the CMOS Setup Utility allow you to config-
ure how some of your system’s features work. These are:
• BIOS Features Setup
• Power Management Setup
The CMOS Setup Utility is a program that is permanently
stored in the BIOS chip on the mainboard. The utility creates a
system hardware configuration record that it stores in a small
amount of battery-supported memory on the board. The BIOS
uses this record to function as an interface between the system
hardware and the operating system. Most of the settings in the
CMOS Setup Utility are made automatically, so you won’t nor-
mally need to use this program. You can, however, customize
some of the operational features to suit how you prefer to use
the system.
Thescreen illustrations on thenext two pages showtheSetup
Default settings for these two sections of the utility.
The CMOS Setup Utility Summary in Section 4: Reference
Information, lists the setting options for each section of the util-
ity including the two noted above.

P5TX–Apro User’s Manual
2: UsingYourMainboard–2.8
Case Security
The mainboard has a case security feature that will warn if the
system case or ‘chassis’ has been opened since the last time the
system was used. There is a photoelectric cell mounted on the
mainboard that is active when the system is turned off and will
detect the case being opened. The next time you turn the system
on a warning message will appear on screen during the POST
(Power On Self Test) before the Operating System loads.
The J18 connector on the mainboard connects to a chassis
intrusion signal cable.
Cooling Fan Connectors
There are three cooling fan connectors on the mainboard that
support cooling fans with power management features. If you
connect this type of fan, and the ‘CPU FAN Off In Suspend’ line
in the CMOS Setup utility’s Power Management Setup section is
set to Enabled, the system will turn the fans off when the system
is in Suspend mode.
Modem Wake-Up
The J19 connector on the mainboard is for connecting a signal
cable from a modem that supports a modem ring system wake
up feature. With such a modem installed and connected to the
mainboard via this connector, the system will wake up from Sus-
pend mode when an incoming call is received by the modem.
The ‘Ring-In Event’ line in the CMOS Setup utility’s Power
Management Setup section must be set to Enabled for this fea-
ture to function.
Power Supply Selection
There are two power supply connectors on the mainboard.
One is for a standard PS/2–type power supply and the other for
anATXpower supply.Youmustindicate whichtypeisconnected
to the mainboard for power management purposes. You do this
by setting the ‘Power Supply Type’ line in the CMOS Setup
utility’s Power Management Setup section to the correct type.
