Introduction
This mainboard is an Intel 440BX 100MHz highly
integrated high-performance mainboard based on the
advanced Pentium® II 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 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.
