Note :
15-30
For the first time installation with error message on the screen, please leave the system on for about
minutes to recharge the battery, then you can enter the system configuration.
Leave your system on for about 24 hours to recharge the battery fully.
If you have switched off the computer system for more than two weeks, you might be required to repeat step
2 to recharge the battery fully.
Any hard disk cable longer than the standard type is not recommenced for used with PT-429G. Too long
hard disk cable will make the Green PC circuit unable to monitor the hard disk activity.

SECTION 1
INTRODUCTION
1.1 Overview
PT-429G offers a 32-bit programming architecture compatible with the software base of the 486
microprocessor. It is a reliable main board using a UMC chipset and a multi-layer printed circuit hoard
The chipset consists of UM82C491F-AC and UM82C493F which provide the most cost effective and high
xperformance solution for a 486 computer system.
The UK482C491F-AC contains a sophisticated direct-mapped cache controller with write-back operation,
and fast page mode DRAM Controller, AT Bus control logic, data bus conversion logic, CPU reset logic,
clock generation for CPU, keyboard and timer, DMA/refresh logic and peripheral interface logic. The
UMC493F contains a sophisticated VESA Controller which can run up to 5OMHz.
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.
The PT-429G is a VESA Local Bus motherboard The three Local Bus slots fully comply with the VESA (
Video Electronics Standards Association ) Master mode specifications. This means I/O data can run as
fast as CPU. The speed of I/O peripherals can be dramatically increased by connecting VESA compatible
controller cards to the VESA Local Bus slots on the PT-429G.
The PT-429G is a green design mother-board which means when there is no operation on the system for a
while (the period is software programmable), the PT-429G will slow down its original working frequency
to 8 MHz speed This will help to save the power consumption in order to protect our environment. The
PT-429G is equipped with a AUX Green connector which can be connected up to four external Green
devices through our Green cable.
“This is an
ENERGY STAR compliant product.”
“The Environmental Protection Agency ENERGY STAR 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”
PT-429G was authorized by Novell to use the Novell Yes, It runs with Netware certification mark.

INTRODUCTION
1.3 Green PC Power Management
The Green PC mode is a state that minimizes the power consumption. Through the BIOS setting of the
PT-429G can slow down the CPU clock to 8 MHz in Green PC mode. The PT-429G extends the Green PC
feature to four external devices (Green AUX
#l to # 4) by the AUX Green connector (J7 & JP32). The
Green PC mode option of these Green AUX connectors are :
- Remove the sync signals from the video monitor,
- Turn off video monitor power,
- Turn off printer power,
- Turn off hard disk drive power.
PT-429G will be placed into Green PC mode as a result of one of the following events :
- Power save button (GJl) is shorted.
- Expiration of one of five independent Green PC Timers, the 1st timer is used to slow down CPU
speed. The Green PC Timers are software programmable which can configured in the “Power
Management Setup!’ option of the BIOS CMOS setup. (Refer to 5.8 Power Management Setup)
- Execution of the system hot key for power down sequencing <CTRL> <ALT> <\>.
Through the system activity monitoring and management, the PT-429G will not go into Green PC mode
(or leaves Green PC mode and back to normal mode) if any activity is detected on the following signals:
- IRQ1 (Keyboard)
- IRQ3 (COM2)
- IRQ4 (COMl)
- IRQ6 (FDD)
- IRQ7 (LPTl)
- IRQ14 (HDD)
1.4 PT429G System Packages
The
PT-429G mother-board can act as the nucleus to various system con&nations, in order to optimize
your total power saving The following is a brief introduction to add-on cards and peripherals suited to
the
PT429G ;-
(1)
Optimum Power Saving system package.
PT-429G mother-board
Monitoring COMl, COM2, LPT 1, Keyboard, Floppy Drives, Hard Drives.
PT523G,

Turning off the vertical
& horizontal sync of monitors through the unique PT-429G hardware connection.
This hardware connection works in any environment @OS, WINDOWS etc), whereas software drivers
only work in WINDOWS.
PI-626 UMC VESA Local Bus IDE I/O Card
Powerful controller card with added Green
driver.
ECO PAD
This
external device connects to the second unique PT-429G connector to add on/off switching to
peripherals such as printers, monitors and scanners
- All timing and on/off controlled by the PT429G
mother-board. Utilizing a Zero Voltage Protection Circuit the ECO PAD ensures safe and reliable on/off
switching which will not harm your peripherals.
Testing results have shown that a system using the above products consumes only 17.6 watts of power at peak
voltage of 220v. The effective watts RMS) is less than 10 watts. Add an
ECO PAD to this configuration
and this covers your system, monitor, printer and scanner.
Alternative system packages.
The PT429G mother-board is equipped with two unique green connectors, however it can also use
conventional VGA cards to add power saving features to monitors using their respective software driver(s). All
efforts are made to ensure the PT429G is compatible with a wide range of add-on cards.
For further details on PT523G, PT524G, PT528G, PT626 and the ECO PAD please contact your local dealer or
sales representative for assistance.
