1. INTRODUCTION
1.1 Overview
 PT-730A offers a 64-bit programming architecture compatible with the software base of the 486,
586 microprocessor. It is a reliable motherboard using a UMC chipset and a multi-layer printed
circuit board. The chipset consists of UM8891AF (Host Bridge & Cache Memory Controller),
UM8892AF (Write Buffer Data Path Controller) and UM8886AF (ISA Bridge & System I/O
Controller) which provides the most cost effective and high performance solution for a PCI
PENTIUM computer system.
 A block of 128K memory of the system DRAM is used for system and video shadow RAM to
increase the system performance. The video shadow RAM consists of four 16K pages which can
be enabled respectively.
 PT-730A is a PCI Local Bus motherboard. The three PCI Local Bus slots fully comply with the
PCI (Peripheral Component Interconnect) Local Bus Specification Rev. 2.0. The speed of I/O
peripherals can be dramatically increased by connecting PCI compatible interface cards to the
PCI Local Bus slots on the PT-730A. We are the member of PCI SIG (Special Interest Group).
 PT-730A is a green design mother-board which means when there is no system activity for a
specific period of time (this period is software programmable), the PT-730A will slow down its
original working frequency to zero. This will help to save the power consumption, reducing
energy related pollution and protecting our environment. PT-730A is also equipped with a unique
AUX Green connector which can be connected up to an external product, called an ‘ECO-PAD’
which can control the on/off switching of external power devices such as printers, monitors and
scanners, through the motherboard BIOS. If you do not use an ECO-PAD then the same
connector can also be used to control the vertical and horizontal sync of your monitor when
connected to a range of “PT-xxxx” VGA cards. For further information on the ECO-PAD or
other “PT” products please contact your dealer or sales representative.
"This is an ENERGY STARTM compliant product."
The Environmental Protection Agency ENERGY STARTM program defines that as an Ally of this
program the specified manufacturer must produce systems, or system components which enable a
computer system to operate and draw 30 watts or less of power in idle mode. Although the EPA do
not endorse any particular product or service, the program is designed to offer a cooperative effort
between the EPA and the component manufacturer (Ally) to provide energy saving products and
education to customers."
"It runs with Netware"
The PT-730A was authorized by Novell to use the Novell Yes, It runs with Netware certification
mark.

1.3 Green PC Power Management
The Green PC mode is a state that minimizes power consumption. There are three different Green
PC modes :
1) Doze mode. This mode is available for all kinds of CPU. The clock of the CPU will slow
down to 8 MHz.
2) Standby mode. The clock of the CPU will slow down to the pre-set frequency.
3) Inactive mode / Sleep Mode. The PT-730A can stop the CPU clock under this mode.
The PT-730A extends the Green PC feature to a Green AUX connector (JP35). Through this
connector, the user can connect the PT-730A with an ECO-PAD or a range of “PT-xxxx” VGA
cards and IDE I/O cards which have the unique Green Aux connector. This enables :
 ECO-PAD - Turn off video monitor,
 ECO-PAD - Turn off printer (or other peripheral) power.
 PT-xxxx VGA CARD - Turn off the vertical & horizontal sync of the monitor.
(Note : The hardware function on “PT-xxxx” VGA cards is more efficient than a green software
driver (screen saver) as it works with all types of software applications such as DOS or Windows. It
is completely independent of software being used at the time).
The PT-730A will be placed into Green PC mode as a result of one of the following events :
 Suspend switch (JP6) is pressed.
 Expiration of the internal Green PC Timer. The Green PC Timer is software
programmable which can configured in the "Power Management Setup" option of the
BIOS CMOS setup. The power management feature will be enabled as default, however
the timing may differ due to production control. It is recommended that you re-adjust
these timings according to your personal requirements/set-up.
Through system activity monitoring and management, the PT-730A will not go into Green PC mode
if any of the following activity is detected:
 PCI Master 0 activity
 PCI Master 1 activity
 PCI Master 2 activity
 PCI slave activity
 LPT port activity
 COM port activity
 ISA master & DMA activity
 IDE activity
 Floppy activity
 VGA activity
 Keyboard activity

2.3 SIMM MEMORY Configuration
This motherboard supports the 72-Pin SIMM memory.
72-Pin
This type of SIMM is a 32-bit module. (sometimes referred to as “..x32” or “..x36”). There are various types
of this module available ranging from 1MB capacity up to 32MB. However it should be noted that different
types can be split up into two groups - namely “single bank” and “dual bank”. The table below shows the
difference:
SIMM TYPE CAS Signals / bank
For 1 Pc SIMM
TOTAL MEMORY
For 1 Pc SIMM
256k x 32 (Non-
Parity)
one - single bank 1 MB
256k x 36 (Parity) one - single bank 1 MB
512k x 32 (Non-
Parity)
two - dual bank 2 MB
512k x 36 (Parity) two - dual bank 2 MB
1M x 32 (Non-
Parity)
one - single bank 4 MB
1M x 36 (Parity) one - single bank 4 MB
2Mx 32 (Non-
Parity)
two - dual bank 8 MB
2M x 36 (Parity) two - dual bank 8 MB
4M x 32 (Non-
Parity)
one - single bank 16 MB
4M x 36 (Parity) one - single bank 16 MB
8M x 32 (Non-
Parity)
two - dual bank 32 MB
8M x 36 (Parity) two - dual bank 32 MB
Since this motherboard supports the 586/Pentium processor, which has 64-bit architecture, you will require a
minimum of two pieces of SIMM (equal to 64-bit) in order to boot the system.
As such the four SIMM sockets of this motherboard can be looked upon as two separate 64-bit banks.
Although this motherboard can support both single-bank and double bank SIMM, it should be noted that you
cannot mix the two types within a 64-bit bank. Below is a diagram showing the correct and incorrect ways of
using single and dual banked SIMMs.
1M x 32/36 (Single Bank)
1M x 32/36 (Single Bank)
2M x 32/36 (Dual Bank)

1M x 32/36 (Single Bank)
2M x 32/36 (Dual Bank)
As The UMC chipset of this motherboard supports up to 8 CAS signals. Each CAS signal is equal to one 32-
bit bank. Therefore it is possible to use 4 pcs. of dual-banked SIMM allowing up to 128MB on board
memory.
