Introduction
This mainboard is a SiS 620 100MHz high-performance mainboard based on the Slot 1 microprocessor, and provides CPU Plug and Play feature for faster and easier CPU installation. The mainboard features with highly flexible configurations and is fully IBM PC/AT compatible. The mainboard uses a highly integrated Slot 1 chipset with 3D video inside that is built-in a high performance 64-bit 3D AGP Graphics Accelerator with 8MB frame buffer shared from system memory. It 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 an onboard 3D PCI Sound to meet PC98 Audio requirement. It is also built-in Hardware Monitor circuit for abnormal CPU fan speed/temperature/ voltages detection. The mainboard BIOS provides Trend's ChipAway Virus to ensure the entire boot process virus free.

Unpacking the Mainboard & Static Electricity Precautions
This Mainboard package contains the following items: 1. 2. 3. 4. This Mainboard and the Device Driver The Slot1 holder and AT cables This UserÕs Guide
Optional Digital Audio cables/bracket
The mainboard is easily damaged by static electricity. Follow the precautions below while unpacking or installing the mainboard. 1. 2. Do not remove the mainboard from its original package until you are ready to install it. Frequently ground yourself to discharge any static electric charge that may build up in your body while working on installation and/or configuration. For example, you may ground yourself by grasping an unpainted portion of the systemÕs metal chassis. Remove the mainboard from its anti-static packaging and place it on a grounded surface, component side up. Handle the mainboard by its edges or by the mounting bracket to avoid touching its components. Check the mainboard for damage. If any integrated circuit appears loose, press carefully to seat it firmly in its socket. Do not apply power if the mainboard appears damaged. If there is damage to the board contact your dealer immediately.
