SOMETHING IMPORTANT !
¶TRADEMARKS
All trademarks used in this manual are the property of their respective owners.
¶LOAD SETUP DEFAULTS
“LOAD SETUP DEFAULTS” is the function which will have the BIOS default
settings loaded into the CMOS memory. These default settings are the suggested
settings which will optimize system performance and increase system stability Load
the setup default is recommended when you receive this mainboard or when the
system CMOS data is corrupted. Please refer to the Section 4.8 for the procedures.
¶DISCHARAGE CMOS DATA
Whenever you want to discharge the CMOS data or open the system chassis, Make
sure to disconnect the AC power first because there is always the 5V standby voltage
connected to the ATX form-factor mainboard. Without disconnecting the AC power
connector from the PC system, the mainboard can be damaged by any improper
action .
¶WAKE ON LAN
In order to support the Wake On LAN feature, the system requires a special SPS
(Switching Power Supply), Such power supply must be able to provide at least 800
mA of driving capability on the “5V standby” voltage. Please refer to the Section 3.3
for pin assignment.
¶WARNING !
The "Static Electricity" may cause damage to the components on the mainboard, In
order to avoid the damage to the mainboard accidentally, please discharge all static
electricity from your body before touching this mainboard.
¶NOTICE
Information presented in this manual has been carefully checked for reliability;
however, no responsibility is assumed for inaccuracies. The information contained in

1. INTRODUCTION
1.1 OVERVIEW
This Mainboard is a high performance personal computer mainboard. It is the
baby-AT form-factor with both Slot 1 (optional) and Socket 370 designed on the
board for different type of CPU package. The Intel® i810 chipset is chosen as the
core logic of the mainboard to give the most outstanding performance and
reliability. It is designed for 233, 266, 300, 333, 350, 366, 400, 433, 450, 466, 500,
550, 600MHz and higher speed Pentium™ II/III and Celeron™ processors
This mainboard has built-in two channels of “PIO” and “Ultra DMA33/66 Bus
Master” mode PCI IDE ports to connect the modern IDE devices. In addition, one
Floppy Disk control port, two high speed Serial ports (UARTs), one multi-mode
Parallel port, One PS/2™ mouse port, one IR interface and two USB ports are
designed on the board.
There are the 3D PCI audio and AGP VGA interfaces built on the board. These
onboard interfaces are the PnP devices (Plug and Play) and they are fully
compatible with the Windows environment. So you don't have to purchase another
sound card or VGA card because they are integrated on the mainboard.
Pentium™ II, Pentium™ III and Celeron™ are the 32-bit processors with RISC
technology, which offers several key features such as built-in 512K/256K/128K L2
cache, 12-stage super-pipeline architecture, out of order execution … etc. In order
to optimize of its capabilities and performances, the 32-bit Operating System (such
as Windows 95®, Windows 98®, Windows NT® and OS/2™ …etc.) and 32-bit
applications are recommended.
The 810 chipset is designed to support the 66MHz and 100MHz Front Side
Bus (FSB) CPUs. There is the CPU booster which comes with the 810DT+
and it will allow you to install 133MHz FSB Pentium III processor on the
socket 370 connector and deliver the performance of PC-133 architecture.
Please refer to the following picture for the outlook of the CPU booster:
Install the CPU booster on Slot 1 allows you to use the 133MHz FSB CPU on
socket 370 and it will increase the system performance.

1.2 AIR BUS -
There is a revolutionary new interface designed on the mainboard - the AIR Bus (
CN25 ). There is the "KEYBIOS" device is designed to connect to the AIR Bus
and it will give you lots of incredible features to your PC system.
Why AIR Bus?
One of the most significant and immediate feature from AIR bus is it will rescue
your system BIOS from virus attack. There was a virus called CIH virus and it
made users start to aware that the virus could also make serious damage to the
mainboard. Such virus will kill the system BIOS and make PC system failed to
work. Unfortunately, similar virus will become popular and the protection to the
mainboard will be surely necessary and extremely important.
Everyone can see that the PC system will be failed to boot when the system BIOS
is destroyed. There is no perfect prevention for such virus attack because there is
always the new virus invented. However, AIR Bus can be one of the best solution
to rescue your PC system from virus attack because it is an intelligent interface and
it will restore the system BIOS automatically.
In case that the PC system is infected by virus and the system BIOS is destroyed,
users have to call for help or send the PC system to the dealer for trouble shooting.
However, you do have to wait for such technical support because the AIR Bus will
have the system BIOS get recovered within a single minute. The recovery
procedure is done automatically and you do not have to make any hardware or
software setting. Simply plug in the " KEYBIOS " and click on the power button,
and then leave everything done by the " KEYBIOS ".
Besides, the " KEYBIOS " can be used as a spare copy of the system BIOS. No
matter how serious of damage is made to your system BIOS, whenever there is the
" KEYBIOS " connected to the AIR Bus, the system BIOS will be replaced by
the " KEYBIOS " and that will keep your PC system alive.
More than just a mainboard.
The " KEYBIOS " is a programmable device and many special software tools
can be introduced on it. Since " KEYBIOS " is active before the OS is loaded, so
it will provide lots of amazing feature. For example, the " KEYBIOS " can be
used for security purpose and that will keep the unauthorized person away from
your PC system. The design of the AIR Bus is simple, but the features introduced
to the " KEYBIOS " will come out with many amazing function and you will
discover that what you received is more than just a regular mainboard. Please
contact your dealer for more detail features on the AIR bus.

1.3 CPU BOOSTER
The 810DT+ comes with a CPU booster and it will allow you to install 133MHz
FSB Pentium III processor on the socket 370 to increase the system performance.
Why CPU Booster?
Over clock is popular to many users. Unfortunately, over clock the CPU may cause
serious damage to the CPU and mainboard. However, the CPU booster will increase
the system performance by changing the memory architecture to PC-133 and you do
not have to worry about the potential damage.
When CPU booster is installed on the mainboard. CPU and the memory subsystem
are both running at 133MHz and the system performance will be increased instantly.
When CPU booster is installed, it will provide the following features:
1. 810 mainboard will be able to support 133MHz FSB Pentium III processors.
2. The memory architecture will be changed from PC-100 to PC-133.
INSTALLATION OF CPU BOOSTER
When the CPU booster installed onto the slot 1 connector, it will fine-tune the
mainboard coupling interface so that you can use 133MHz FSB CPU. Please refer to
the following picture for the outlook of the CPU booster.
In order to make the CPU booster working normally, please refer to the following
notice when use CPU booster to increase the performance:
1. The Slot 1 connector supports only 66/100MHz FSB CPUs.
2. When CPU booster is not installed on the mainboard, you can install either 66MHz
or 100MHz FSB CPU onto the Socket 370.
3. When CPU booster is installed on the Slot 1, you can install 133MHz FSB CPU on
to the Socket 370 connector,
4. Always use PC-133 DIMM module when CPU booster is installed and refer to the
following to install the DIMM module.
