FCC and DOC Statement on Class B
This equipment has been tested and found to comply with the limits for a Class
B digital device, pursuant to Part 15 of the FCC rules. These limits are designed
to provide reasonable protection against harmful interference when the
equipment is operated in a residential installation. This equipment generates, uses
and can radiate radio frequency energy and, if not installed and used in
accordance with the instruction manual, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not occur
in a particular installation. If this equipment does cause harmful interference to
radio or television reception, which can be determined by turning the equipment
off and on, the user is encouraged to try to correct the interference by one or
more of the following measures:
 Reorient or relocate the receiving antenna.

1.1.1 Features / Caractéristiques / Leistungsmerkmale
Chipset
 Intel

440LX AGPset
Processor
The system board is equipped with Intel

Socket 370 for installing
an Intel CeleronTM processor that is packaged in PPGA (Plastic Pin
Grid Array). It is also equipped with a switching voltage regulator
that automatically detects 1.30V to 2.0V.
 300A/333/366/400/433/466MHz CeleronTM PPGA processor
System Memory
The system board supports 16MB to 384MB memory. It is
equipped with three 168-pin DIMM sockets using unbuffered
SDRAM DIMM (10/12/13ns), 3.3V. It also supports ECC (uses x72
DRAM).
Expansion Slots
The system board is equipped with 1 dedicated AGP slot, 3
dedicated PCI slots, 1 dedicated 16-bit ISA slot and 1 shared PCI/
ISA slot. All PCI and ISA slots are bus masters.
Desktop Management Interface (DMI)
The system board comes with a DMI 2.0 built into the BIOS. The
DMI utility in the BIOS automatically records various information
about your system configuration and stores these information in the
DMI pool, which is a part of the system board's Plug and Play
BIOS. DMI, along with the appropriately networked software, is
designed to make inventory, maintenance and troubleshooting of
computer systems easier.
Connectors
 2 connectors for external USB ports
 1 connector for IrDA interface
