The ATX BX9 mainboard is a high-performance personal computer
mainboard based on the Intel®Pentium®II processor. This mainboard
combinesleadingedgeAGPATI®3D Rage PRO Turbo/Rage 128VR (re-
served) technology in graphics and Creative®ES1371/ES1373 (reserved) PCI
technology in audio. The Intel®Pentium®II processor supports MMXTM
(Multimedia Extension) technology.
The mainboard uses the highly integrated Intel®82443BX AGP chipset to
support the PCI/ISA and Green standards, and to provide the Host/AGP
bridge. The Intel®82371EB chipset 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 Intel®82371EB chipset also improves the IDE
transfer rate by supporting Ultra DMA/33 IDE that transfers data at the rate
of33MB/s.
The mainboard also supports the System Hardware Monitor Controller as an
optional function. Its functions include: CPU /power supply/chassis fan
revolution detect, CPU/system voltage monitor, system temperature monitor,
and chassis intrusion detect(optional).

HARDWARE INSTALLATION
2.1 Central Processing Unit: CPU
The mainboard operates with Intel®Pentium®II/CeleronTM processor. The
mainboard uses a CPU Slot called Slot 1 for easy CPU installation and a
jumper switch (SW1) to set the proper speed for the CPU. The CPU should
always have a Heat Sink and a cooling fan attached to prevent overheating.

A. OEM Pentium®II Processor Installation Procedures
Different kinds of Pentium®II processor that is currently used: the OEM
version, the Boxed version, and CeleronTM. OEM Pentium®II Processor has
no Heat Sink, Fan and Heat Sink Support, the Boxed Pentium®II Processor
is provided with Heat Sink w/ fan and Heat Sink Support, while the
CeleronTM processor is a plain processor card without cover or heatsink..
Required Things:
Pentium®IIprocessor-Processor.
*RetentionMechanism(RM)- Plastic Guide that holds the S.E.C.Catridge
in the Slot 1 connector.
*RetentionMechanism AttachMount(RMAM)-Bolt/Bridge assemblies
inserted up through the bottom of the
motherboard. RM secures to RMAM ( 2
RMAM required per RM ).
*Heat Sink SupportBase (HSSBASE) - Plastic support bar mounted to
the mainboard under the ATX heatsink.
