The CB650M-BX motherboard integrates the latest advances in processor,
memory, 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
Celeron 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
direct connection between graphics subsystem and system memory.

Overview
CB650M-BX Mother Board
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
manufacturer's instructions.
Caution :

1. Processor :
The CB650M-BX motherboard supports a single Pentium II/III or Celeron
processor. The processor’s VID pins automatically program the voltage
regulator on the motherboard to the required 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
secured by a retention mechanism attached to the motherboard.
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
controller and Accelerated Graphic Port(AGP) interface. The I/O subsystem of
the 82440BX is based on the PIIX4E, which is a highly integrated PCI ISA IDE
Xcelerator Bridge.
2-1. 82443BX PCI/AGP Controller
●Processor interface control
Support for processor host bus frequencies of 100MHz and 66MHz
●Integrated DRAM controller
+3.3V only DIMM DRAM configurations
100MHz or 66MHz SDRAM
●Accelerated Graphics Port interface
Main Features
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.

3. AGP
The integrated AGP is a high-performance bus for graphics-intensive
applications, such as 3D applications. AGP, while based on the PCI Local Bus
Specification, Rev.2.1, is independent of the PCI bus and is intended for
exclusive use with graphical display devices. AGP overcomes certain
limitations of the PCI bus related to handling large amount of graphics data
with the following features:
CB650M-BX(1,2¿Â) 00.5.12 2:8 PM ∆‰¿Ã¡ˆ1-3
CB650M-BX Mother Board
1-4
●Pipelined memory read and write operations that hide memory access
latency
●Demultiplexing of address and data on the bus for nearly 100% bus efficiency
4. USB
The CB650M-BX motherboard has two USB ports;one USB peripheral can be
connected to each port. The two USB ports are implemented with stacked
back panel I/O connectors. The CB650M-BX motherboard fully supports
UHCI and uses UHCI-compatible software drivers.
The +5V lines to these ports are protected with a PolySwitch circuit that, like a
self-healing fuse, reestablishes the connection after an overcurrent condition is
removed.
●Self-identifying peripherals that can be plugged in while the computer is
running
●Automatic mapping function to driver and configuration
●Support for up to 127 physical devices
5. IDE Support
The CB650M-BX motherboard has two independent bus-mastering IDE
interfaces. These interface support:
●ATAPI devices(such as CD-ROM devices)
●ATA devices using these transfer modes
PIO Mode 3
PIO Mode 4
Ultra DMA/33 synchronous-DMA mode
Computer systems that have an unshielded cable attached to a USB
port may not meet FCC Class B requirements, even if no device or a
low-speed USB device is attached to the cable. Use shielded cable that
meets the requirements for full-speed devices.

6. Real-Time Clock, CMOS RAM, and Battery
The real-time clock is compatible with DS1287 and MC146818 components.
The clock provides a time-of-day clock and a multi-century calendar with
alarm features and century rollover. The real-time clock supports 256 bytes of
battery-backed CMOS SRAM in two banks that are reserved for BIOS use.
A coin-cell battery powers the real-time clock and CMOS memory. When the
computer is plugged into a wall socket, the battery has an estimated life of
three years. When the computer is plugged in, the 3.3V standby current from
the power supply extends the life of the battery. The clock is accurate to +13
minutes/year at 25˚C with 3.3V Stand-by voltage applied.
7. I/O Controller
The IT8671F controller from ITE is an ISA Plug and Play-compatible,
multifunctional I/O device that provides following features:
●Two serial ports
●One parallel port with ECP and EPP support
●Interface for one 1.2MB, 1.44MB, and 2.88MB diskette drive
●PS/2 style mouse and keyboard interfaces
The BIOS Setup program provides configuration options for the I/O
controller.
7-1. Serial Ports
The motherboard has two 9-pin D-sub serial connectors located on the back
panel. The serial ports support NS16C550-compatible UARTs and can be
assigned as COM1(3F8), COM2(2F8), COM3(3E8), or COM4(2E8).
7-2. Parallel Ports
The connector for the multimode bidirectional parallel port is a 25-pin D-Sub
connector located on the back panel.

The I/O controller support two diskette drive that is compatible with the
82077 diskette drive controller and support both PC-AT and PS/2 modes.
7-4. Keyboard and Mouse Interface
PS/2 keyboard and mouse connectors are located on the back panel. The +5V
lines to these connectors are protected with a Fuse circuit from an overcurrent
condition.
8. Audio Subsystem
The audio subsystem contains of these devices.
●Yamaha YMF724F or YMF740C
●AKM AK4542 stereo audio codec or compatible part

values
CB650M-BX(1,2¿Â) 00.5.12 2:8 PM ∆‰¿Ã¡ˆ1-6
CB650M-BX Mother Board

When suggested ratings for temperature, fan speed, or voltage are exceeded,
an interrupt is activated.
10. Wake on LAN Technology
Wake on LAN technology enables remote wakeup of the computer through a
network. Wake on LAN technology requires a PCI add-in network interface
card(NIC) with remote wakeup capabilities. The remote connector on the NIC
must be connected to the motherboard Wake on LAN connector. The NIC
monitors network traffic at the MII interface;upon detecting a Magic Packet,
the NIC asserts a wakeup signal that powers up the computer.
11. Wake on Ring
Wake on Ring enables the computer to wake from sleep or soft-off mode when
a call is received on a telephony device, such as a faxmodem, configured for
operation on either serial port.
12. Expansion Slots
●One AGP slot
●Two dedicated PCI slots
●One shared ISA/PCI slot
