1. Introduction

Overview

The CB650M-BX motherboard integrates the latest advances in pro c e s s o r,
m e m o r y, and I/O technologies into a Micro ATX form factor(244x205mm) that
combines performance, flexibility, and easy of use into high integrated capable
of meeting a variety of price/performance levels.

The CB650M-BX motherboard supports Intel Pentium II/III processor or
C e l e ron processor based on the Intel 440BX AGPsets(82443BX and 82371EB).
The CB650M-BX motherboard supports not only a 66MHz host but also a
100MHz host bus. So Intel Pentium II/III 350~450MHz processor and
Pentium II/III(Katmai) processor with a 100MHz host bus can be supported
for higher performance level. Two standard 168-pin DIMM Sockets with
memory size up to 256MB support Synchronous DRAM memory.

The Intel 82371EB PCI-to-ISA/IDE Xcelerator(PIIX4E) provides an integrated
Bus Master IDE controller and Ultra DMA/33 with high performance IDE
interfaces for up to four devices.

In addition, the CB650M-BX comes with an AGP(Accelerated Graphics Port)
bus slot, a faster than the current 33MHz PCI bus. The AGP bus provides a
d i rect connection between graphics subsystem and system memory.

Caution :

There is the danger of an explosion if the battery is incorrectly replaced.
Replace the battery with the same or equivalent type recommended
by the manufacturer. Discard used batteries according to the battery

Main Features

1. Processor :

The CB650M-BX motherboard supports a single Pentium II/III or Celero n
p ro c e s s o r. The pro c e s s o r’s VID pins automatically program the voltage
regulator on the motherboard to the re q u i red processor voltage. The host bus
speed(66MHz or 100MHz) is automatically selected. The processor connects to
the motherboard through the 242-pin Slot 1 connector. The processor must be
s e c u red by a retention mechanism attached to the motherboar d .

Caution :

The CB650M-BX motherboard supports Pentium II/III processor with a 100
or 66MHz host bus and Celeron processor with a 66MHz host bus.
Processor with a 100MHz host bus should be used only with 100MHz
SDRAM;the motherboard will not operate reliably if a processor with a
100MHz host bus is paired with 66MHz SDRAM. However, processors with
a 66MHz host bus can be used with either 66MHz or 100MHz SDRAM.

2. Chipsets :

The Intel 82440BX AGPset consists of the Intel 82443BX PAC and the Intel
82371EB PIIX4E bridge chip. The PAC provides an optimized DRAM

CB650M-BX Mother Board

Installing the System Memory

The C B 6 5 0 M - B X m o t h e r b o a rd uses only DIMMs. Two sockets are available for

3.3V unbuff e red SDRAM for up to 256MB of SDRAM.

1. General DIMM Notes

■For the Host bus to operate at above 100MHz, use only PC100-compliant

DIMMs. The CB650M-BX motherboard operates at 100MHz, thus most
systems will not even boot if non-compliant modules are used because of
the strict timing issues involved under this speed. If your DIMMs are not
PC100-compliant, set the Host bus frequency to 66MHz for the system
s t a b i l i t y.

■Single-side and double-side memory modules are supported.

■BIOS shows SDRAM memory and using banks on bootup scre e n .

2. Memory Configuration

DIMM memory configuration is auto-banking and there f o re does not need to
be installed in any particular ord e r. The following table lists a number of
possible memory configurations.

Chapter 3.

This chapter provides information on how the SETUP program allows you to
c o n f i g u re the function and device of your computer and how to configure
each item on the SETUP menus.

B e f o re the computer can operate, it must know what devices are installed in it.
These devices include floppy and fixed-disk drives, video, and so forth. Ta k e n
t o g e t h e r, the presence or absence of these devices comprise the system
configuration. Use the SETUP program to verify or change the system
c o n f i g u r a t i o n .

BIOS Setup

BIOS Setup

O rd i n a r i l y, there should be no need to run SETUP the first time you start your
system, since your computer comes from the factory ready to use. You must,
h o w e v e r, run the SETUP program each time you make any changes to your
computer's configuration, such as adding drives, and so forth. you can also
run it to verify the system configuration.

Starting SETUP3.1

The SETUP program is permanently stored in a "Flash EEPROM" and not
contained on disk.
The SETUP program can be accessed:

■ When powering up the system and When resetting the system

■ When the system detects an error and prompts for the SETUP pro g r a m
