The mainboard features with highly flexible configurations and is fully IBM PC/AT compatible. The mainboard uses a high-end AGPset chipset that supports the PCI/ISA and Green standards, it provides the Host/AGP bridge, and integrates all system control functions such as ACPI(Advanced Configuration and Power Interface). The ACPI provides more energy saving features for the OSPM(OS Direct Power Management) function. The mainboard has a built in high performance 64-bit 3D AGP Graphics Accelerator with 8MB frame buffer and an onboard 3D PCI Sound to meet PC98's specifications for 3D Multimedia systems. Built-in Hardware Monitor circuit to monitor CPU/Chasis temperatures/fan speeds/voltages with AMI Desktop Client Manager and options to support Intel LANDesk Client Manager(LDCM). The mainboard BIOS provides Trend's ChipAwayVirus to ensure the entire boot process virus free. 2 Chapter 1 Key Features The advanced features of the mainboard include: t Intel 440BX AGP chipset: -- supports Pentium® II 233~500MHz and Celeron 266~433MHz CPUs -- supports both 66.6MHz and 100MHz FSB (Front Side Bus) -- provides CPU Plug and Play feature for faster and easier CPU installation t Memory: -- provides 3 DIMMs for SDRAM/EDO (for 66MHz FSB only) memory modules -- supports a maximum size of 768MB system memory -- supports ECC Error Correct function Expansion slots: -- provides 3 PCI, and 1 ISA slots; Onboard 2 IDE ports: -- supports 4 IDE devices maximum -- supports PIO, PCI Bus Master, and Ultra DMA/33 operation modes ATX Power Supply: -- provides ATX power connector and features of ATX power -- provides Power Button/Suspend Switch -- provides Alarm, LAN and Modem Wake Up t t t Introduction 3 Onboard DC-DC Step Down Regulator: -- complies with Intel VRM V8.2 specification Onboard 64-bit 3D AGP Graphics Accelerator, -- supports AGP Ver1.0 specification (x1 or x2) -- provides 8MB frame buffer -- high resolution graphic modes up to 1600x1200 Onboard CMI 8338 PCI Sound, -- full duplex playback and recording, built-in 16-bits CODEC. -- HRTF 3D positional audio, supports both Direct Sound 3D® and A3D® interfaces, and support four channel speakers mode. -- supports Windows 3.1/95/98 and Windows NT 4.0. -- built-in 32 ohm earphone buffer and 3D surround. -- supports MPU-401 Game/Midi port and SB16 -- downloadable Wave-table Synthesizer support Direct Music®. -- Digital Audio Interface(SPDIF) IN/OUT up to 24-bit stereo 44KHz sampling rate voice and measured 120dB audio quality. -- Stereo Mixer supports analog mixing from CD-Audio, Line-In, and digital mixing from voice, FM/Wavetable and digital CD-Audio.

This Mainboard and the Device Driver 2. The Slot1 Holder and AT cables 3. This User's Guide and COM2 cable/bracket 4. Internal SPDIF/IN cable (optional) 5. Optional Digital Audio cable/bracket The mainboard is easily damaged by static electricity. Follow the precautions below while unpacking or installing the mainboard. 1. Do not remove the mainboard from its original package until you are ready to install it. 2. Ground yourself to discharge static electricity that may build up in your body while working on the installation and/or configuration. For example, you may ground yourself by grasping an unpainted portion of the systemÕs metal chassis. 3. Remove the mainboard from its anti-static bag and place it on a grounded surface, component side up. 4. Handle the mainboard by its edges or by the mounting bracket. Avoid touching its components. 5. Check the mainboard for damage. If any integrated circuit appears loose, press carefully to seat it firmly in its socket. 6. Do not apply power if the mainboard appears damaged. If there is a visible damage on the board contact your dealer immediately. Chapter 2 Hardware Configuration Before you install the mainboard into the system chassis, you may find it convenient to first configure the mainboard's hardware. This chapter describes how to set jumpers and install memory modules, and where to attach components, however, the CMOS jumper is set on "Clear" position when this mainboard is shipped. You will need to set it to "Normal" position in order for the mainboard to perform properly. Warning: Set RTC to "Normal" position before setting other jumpers or memory modules. This mainboard will not function properly if you fail to do so.

Mainboard Component Locations 8 Chapter 2 CPU Installation This mainboard supports Intel Pentium® II CPU by a Single Edge Contact(SEC) slot and a retention clip set which is fit for 3 different mechanical types of Intel CPU (SEPP, SECC and SECC2). The following drawing shows the retention clip set. It has been preinstalled before shipping to make the CPU installation easier for users. However, there are still a few more steps needed to complete the CPU installation, please refer to the following procedures. Hardware Configuration 9 Installation Procedures Follow the following steps in order to install your intel Pentium® II properly. Step 1: Make sure that the mainboard is set in the same direction as the following drawing before installing. Sound VGA Chipset Chipset + 10 Chapter 2 Step 2: There is one set of Slot1 retention Holder which was installed on your motherboard. The two chutes of the retention Holder are screwed in. Lift up both chutes as shown in the drawing. Step 3: Flatten the two latches on the side of the CPU. Insert CPU into the retention Holder. Lock the two latches to secure CPU. If Celeron CPU is installed on CPU card, please continue the following steps. Hardware Configuration 11 Step 4: After installing CPU card ...
