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)

3 Direct Memory Access
Each DMA channel is supported by the system. Two Intel 8237-5 DMA controller chips (Four channels in
each
chtp)
are used. DMA channels are assigned as follows
:
Channels from 0 through 3 are contained in DMA controller 1. Transfers of 8-bit data S-bit
I/O
adapters
and 8-bit or 16-bit system memory are supported by these channels. Each of these channels will transfer
data in 64KB blocks throughout the 6-megabyte system address space.
Channels from 4 through 7 are contained in DMA controller 2. To cascade channels 0 through 3 to the
microprocessor, use channel
1.
Transfer of
16-bit
data between 16-bit adapters and 16-bit system memory
are then supported by channels 5, 6,
&
7. DMA channels from 5 through 7 transfer data in
128K
blocks
throughout the 16-megabyte system address space.
These channels will not transfer data on odd-byte bowdaries.
The address for the page register is as follows :

About CMOS Setup
After the
PT-429G
mainboard has been integrated into the system, you need to run the Setup Program to
set system configuration. Upon finishing the Setup Program is then stored in read-only memory (ROM),
and can only be accessed when you turn on or reset the system.
The settings you specify with the Setup program are recorded in a special area of memory called CMOS
RAM. This memory is backed up by a battery so that it will not be erased when you turn off or reset the
system. Whenever you turn on the power, the system reads the settings stored in CMOS RAM and
compares them to the equipment check conducted during the POST. If an error occurs, an error message
will be displayed on screen, and you will be prompted to run the Setup program.
The
AMI
BIOS Setup program is accessed through a menu which allows you to easily configure your
system. Standard CMOS Setup allows you to record basic system information regarding date and time,
video type and installed drives. Advanced CMOS Setup gives you access to the advanced features
supported by the
AM1
BIOS and your mainboard
chipset.
5.2 Entering CMOS Setup
-
When you turn on the system and in the course of the system
POST,
you will be presented with the
screen depicted below.
To enter the Setup program at this time, press the [Del] key. This will display the first page of the
AMI
BIOS Setup menu.
-
If you do not press the
PEL]
key at the right time, press [Ctrl-Ah-Del] to restart the system and try
again.
-
If you do not press the key at the correct time and the system fails to boot, an error message
KEYBOARD ERROR will be displayed and you will again be asked to
:
RUN SETUP UTILITY
Press
<F
l>
to resume
If you press and hold the [Ins] key while the system is booting until you bear a single beep, the
default Setup values will be loaded into CMOS. Release the key after the beep to prevent a
keyboard error.
After you enter into the Setup Program, a main menu of the
AMI
Setup Program is shown,
-
Select Standard CMOS Setup to access the Standard CMOS Setup menu, which is discussed in section
5.5.

Setup menu, which is discussed in section
5.7.
Select Auto Configuration with BIOS Defaults to load the default system values. You will be prompted
for confirmation, and notified that the values have been loaded.
Select Auto Configuration with Power-On Defaults to load the default power-on values, which disable
all
performance options. This option serves a useful diagnostic function in the event of a compatibility
problem. You will be prompted for confirmation, and notified that the values have been loaded.
Select Change Password to access the password security menu, which is discussed in section 5.8 below.
Select Hard Disk Utility to access the hard disk utility menu, which is discussed in section 5 9 below.
Select Write to CMOS and Exit to save your configuration and exit the Setup program. You will be
prompted for confirmation before the changes are written to CMOS and the system reboots.
Select Do Not Write to CMOS and Exit to cancel any changes to your configuration and exit the Setup
program. You will be prompted for confirmation before the system reboots.
A warning message will appear each time you select Standard or Advanced CMOS Setup.
5.3 Getting Help
-
Help screens are displayed for each option in the Standard CMOS Setup menu. and can be accessed in
the Advanced CMOS Setup menu by pressing
Fl],
A “popup” window till appear, similar to the one
ptctured below, listing the available selections for that option. To exit the Help window, press any key.
