Introduction
This mainboard is a versatile high-end and workstation class
product with an ATX form factor. The mainboard features dual
Socket 370 CPU sockets which uses an Intel CeleronTM PPGA/FC-
PGA series processors, or dual FC-PGA Pentium III series
processors, or a Cyrix III series processors at 66/100/133MHz
FSB.
The mainboard incorporates the VIA 82C694X and VT82C686B
chipsets, features an AC97 audio codec built-in. The mainboard
delivers high-level performance with a 4xAGP (Accelerated
Graphics Port) slot and two us Master Ultra DMA (UDMA) ports
that support four ATAPI (AT Attachment Packet Interface)
devices. The IDE also supports PIO Mode 3 and 4,
UDMA33/66 100 IDE, and an ATAPI CD-ROM.
The mainboard also has a full set of ATX I/O ports, such as two serial
port connectors, a parallel port connector, a dual US (Universal
Serial us) connector, and PS/2 keyboard and mouse connectors. An
extra US header gives you the option of connecting two more US
ports.
One AGP slot, four PCI local bus slots, and one AMR riser slot
provide expandability for add-on peripheral cards.

Static Electricity Precautions
Components on this mainboard can be damaged by static
electricity. Take the following precautions when unpacking the
mainboard and installing it in a system.
1. Keep the mainboard and other components in their original
static-proof packaging until you are ready to install them.
2. During installation, wear a grounded wrist strap if possible. If
you don’t have a wrist strap, discharge static electricity by
touching the bare metal of the system chassis.
3. Handle the mainboard carefully by the edges. Avoid touching
the components unless it is absolutely necessary. During
installation put the mainboard on top of the static-protection
packaging it came in with the component side facing up.
Pre-Installation Inspection
1. Inspect the mainboard for damage to the components and
connectors on the board.
2. If you suspect that the mainboard has been damaged, do not
connect power to the system. Contact your mainboard vendor
and report the damage.
