Static Precautions
Static electricity can be a serious danger to the electronic components on this mainboard. To
avoid damage caused by electrostatic discharge, observe the following precautions:
üDon’t remove the mainboard from its anti-static packaging until you are ready to install
it into a computer case.
üBefore you handle the mainboard in any way, touch a grounded, anti-static surface, such
as an unpainted portion of the system chassis, for a few seconds to discharge any built-
up static electricity.
üHandle add-in cards and modules by the edges or mounting bracket.
Installing the CPU
üWARNING: Use of a CPU Cooling Fan to prevent CPU
from overheating is highly recommended. The Fan
should be installed first before inserting the CPU into
its socket.
1. Locate the ZIF (Zero Insertion Force) Socket 7. This
socket supports Pentium (P5) CPUs (75-233Mhz).
2. First open the socket by pulling the lever sideways,
then upwards. Notice how the lever locks in place
when pressed all the way down.
3. The CPU must be inserted with the correct orientation.
One corner of the CPU has a “notch” and looks
different that the other three. This corner is also
missing a pin unlike the other three and is marked with a white dot on top of the CPU.
Align this corner towards the end of the lever as shown in the figure below. Insert the
CPU, press it down, and close the lever until it locks into place.
Connecting the CPU Cooling Fan (J12)
This mainboard features a fan monitoring function to alert you when
the cooling fan starts to malfunction (Refer to page 27). If you are using
a fan with the standard 4-pin Molex-Type Power-Supply connector, you
should use the fan adaptive cable provided as shown:

INSTALLING THE CPU AND MEMORYINSTALLING THE CPU AND MEMORY
P5T30-B4 User’s Manual
10
Plug the Molex-Type connector of the adaptive cable to the fan’s power connector and plug
the other 3-pin Header Connector to J12, regardless of the polarity. If your Fan provides this
3-pin Header Connector, simply plug it into J12, regardless of the polarity.
Setting the CPU Clock Selection Jumper (JBF0-2 & JFS0-2)
After installing the CPU, you must set the clock selection jumper to match the frequency of
the CPU. Find the Jumper Blocks labeled JBF0-2 and JFS0-2 on the mainboard (Refer to
the diagram on page 8). Set the jumper according to the table below for your CPU
frequency.

Power Supply Connector
The two cables from the standard 5-volt power supply connect to
the power connector on the mainboard (refer to page 6). You
must align the connectors on the power cable at a slight angle to
correctly fit them onto the mainboards power connector. Then,
press down on the connectors to lock them in place. The (2)
connectors should be installed so that the BLACK wires meet in
the middle of the connector.
This mainboard also features a supplementary ATX Power
Connector. Please refer to Appendix A for details.
Serial and Parallel Ports
The cables from the supplied serial port connector bracket hook to the COM1 and COM2
connectors on the mainboard. Generally, the upper serial port on the bracket would be
configured as COM1 and the lower port as COM2. Make sure to orient Pin-1 marked on the
mainboard to the RED stripe on the ribbon cables.
IrDA-compliant infrared module connector
The IrDA connector bracket hooks directly to this connector on the
mainboard. This connector provides support for the optional wireless
transmitting and receiving infrared module. You must first configure
through “UART2 Mode” in INTEGRATED PERIPHERALS SETUP
where UART2 is directed, COM2 or IrDA. (* Pin-6 is reserved for
consumer IR input - remote control *)
USB Connector
This 8-pin connector permits connection of two USB peripheral
devices directly to the system without an external hub.

Keyboard Connector
This connection is for a standard IBM-compatible keyboard. May also be known as a 101
enhanced keyboard.
PS/2 Mouse Connector
If you are using a PS/2 mouse, you must purchase the optional
connector bracket. This bracket mounts in one of the slots in the
back of the case, and features a circular external connector for
the PS/2 mouse, plus a 6-pin ribbon cable that connects to the
PS/2 mouse connector on the mainboard.
Floppy drives
The on-board floppy controller supports (2) floppy disk drives with the floppy ribbon cable
provided. Make sure the RED stripe on the ribbon cable is oriented towards Pin-1. Notice
the “twist” between the sets of connectors on the floppy cable. The floppy drive “A”
position is at the END of the cable, whereas floppy drive “B” is hooked to one of the
connectors on the other side of the twist. The cable provides both “Edge” and “Pin”
connectors for both the A and B positions to match the connector on your floppy drives.
IDE Hard Drives and CD-ROMs
The on-board Enhanced IDE controller can support up to (4) IDE hard drives or other
ATAPI devices, such as CD-ROMs. This controller, as with all Enhanced IDE controllers,
consists of both Primary and Secondary ports. Each port has an associated connector and
cable which can support up to (2) ATAPI devices each.
All IDE devices have jumpers which allow the user to configure the device as either
“Master” or “Slave”. A Master device is one that is ALONE on the IDE cable, whereas a
Slave device is installed as a SECOND device on the same cable. Keep in mind that the
Master device will appear before the Slave device in the CMOS Setup, as well as the
Operating System software. *Refer to the device documentation for jumper settings.
The Secondary IDE port can be used for up to (2) additional ATAPI devices. Normally it’s
recommended that you connect your first hard drive to the Primary port, and the first CD-
ROM to the Secondary.
Make sure to align the RED stripe on the ribbon cable with Pin-1 on the mainboard IDE
connector. On most hard drives and CD-ROMs, the RED stripe should be oriented towards
the power connector of the device.

MAINBOARD BIOS SETUPMAINBOARD BIOS SETUP
P5T30-B4 User’s Manual 17
About the BIOS
The Mainboard BIOS (Basic Input/Output System) acts as the bridge between your
Hardware (CPU, Disk Drives, Video, etc.) and Operating System Software (Windows 95,
OS/2 and so on…) The BIOS Setup (also called CMOS Setup) is where many hardware
configuration options are set and stored. This configuration information will remain in the
BIOS until it is changed, or cleared by removing the battery for a while and then putting it
back.
CMOS (Complementary Metal Oxide Semiconductor) refers to the chip in which the BIOS
information is stored.
The P5T30-B4 mainboard features Award BIOS, which provides an easy to use Setup
program to aid in hardware configuration. In this section we will look at the various menus
and options contained in the Award BIOS Setup Program. This mainboard also features a
“Flash” BIOS. A Flash BIOS can be upgraded via software, thereby eliminating the need to
actually replace the “BIOS Chip” on the mainboard. Procedures for updating the BIOS
follow this section.
The Award BIOS installed in your computer system’s ROM (Read Only Memory) is a
custom version of an industry standard BIOS. This means that it supports Intel/Cyrix/AMD
processors in a standard IBM-AT compatible input/output system.
Using Setup
In general, you use the arrow keys to highlight items, press <Enter> to select, use the
PageUp and PageDown keys to change entries, press <F1> for help and press <Esc> to quit.
Getting Help
Pressing F1 will display a small help window that describes the appropriate keys to use and
the possible selections for the highlighted item. To exit the Help Window press <Esc>.
A Final Note About Setup
Not all systems have the same Setup. While the basic look and function of the Setup
program remains the same for all systems, individual motherboard and chipset combinations
require custom configurations. For example, you may find that your Setup main menu has a
different number of entries from the main menu displayed in this manual. These are simply
features not supported (or not user configurable) on your system.
The final appearance of the Setup program also depends on the Original Equipment
Manufacturer (OEM) who built your system. If your OEM has decided that certain items
should only be available to their technicians, those items may very well be removed from
the Setup program.
