Federal Communications Commission (FCC) Statement
This equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to Part 15 of FCC Rules. These limits are designed to provide reasonable
protection against harmful interference in a residential installation. This equipment
generates, uses and can radiate radio frequency energy and, if not installed and used in
accordance with instructions contained in this manual, may cause harmful interference
to radio and television 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
- INCREASE THE SEP ARATION BETWEEN THE EQUIPMENT AND THE RECEIVER
- CONNECT THE EQUIPMENT INTO AN OUTLET ON A CIRCUIT DIFFERENT FROM
THAT OF THE RECEIVER
- CONSULT THE DEALER OR AN EXPERIENCED AUDIO/TELEVISION TECHNICIAN
NOTE: Connecting this device to peripheral devices that do not comply with Class B
requirements, or using an unshielded peripheral data cable, could also result
in harmful interference to radio or television reception.

The user is cautioned that any changes or modifications not expressly approved
by the party responsible for compliance could void the user’s authority to
operate this equipment.
To ensure that the use of this product does not contribute to interference, it is
necessary to use shielded I/O cables.

HARDWARE CONFIGURATION
The Pentium® II motherboard is based on the Intel® 82440LX Chipset. The
chipset is a highly integrated solution for a cost-effective and compact
motherboard. The motherboard supports 3.3V EDO and SDRAM. Features
on-board include super-I/O, Ultra DMA33, PCI bus master IDE, AGP Ver 1.0,
PCI Ver 2.1 compliant, USB, VRM 8.1 compliant, ECC, LM79/75 System
monitoring (optional).
Key Features
Processor
• Full support for the Intel
Slot 1connector.
• Supports 60 and 66MHz bus speed including all Pentium® II and Celeron
processors operating from 200MHz to 333MHz.
VRM (Voltage Regulator Modules) on Board
• Flexible motherboard design with on-board VRM 8.1, easy to upgrade
with Intel’s future overdrive processors.
Cache
Pentium® II Processor built-in L2 cache (Tag RAM and 2 or 4 BSRAMs for
256KB or 512K).
System Memory
• Up to 384MB (SDRAM) or 768MB (EDO).
• A total of three 168-pin DIMM sockets(3.3V EDO/Synchronous DRAM).
• Supports 3.3V Extended Data Output (EDO) DRAM at 50 and 60ns
speed and Synchronous DRAM up to 66MHz.
• The board has DIMM sockets arranged as banks 0, 1 and 2. You can
install DIMMs in any of the three banks, and use different size DIMMs in
different banks. The BIOS detects the size and type of installed memory .
