Desktop Management Interface (DMI)
The system board comes with a DMI 2.0 built into the BIOS. The
DMI utility in the BIOS automatically records various information
about your system configuration and stores these information in the
DMI pool, which is a part of the system board's Plug and Play
BIOS. DMI, along with the appropriately networked software, is
designed to make inventory, maintenance and troubleshooting of
computer systems easier. Refer to Chapter 4 for instructions on
using the DMI utility.

Integrated Peripherals setup of the Award BIOS in Chapter 3 for
more information.
Important:
 The power button will not function once a keyboard
password has been set in the KB Power On Password
field of the Integrated Peripherals setup. You must type the
correct password to power-on the system.
 The 5VSB power source of your power supply must
support ≥ 720mA (minimum).

CB64-ZX
Note:
The illustrations on the following pages are based on the CB64-BX
system board, which is the board equipped with three DIMM sockets.
Warning:
Electrostatic discharge (ESD) can damage your system board, processor, disk
drives, add-in boards, and other components. Perform the upgrade instruction
procedures described at an ESD workstation only. If such a station is not
available, you can provide some ESD protection by wearing an antistatic wrist
strap and attaching it to a metal part of the system chassis. If a wrist strap is
unavailable, establish and maintain contact with the system chassis throughout
any procedures requiring ESD protection.

2.2 System Memory
The CB64-BX system board is
equipped with three 168-pin DIMM
(Dual In-line Memory Module)
sockets that support x64/x72
unbuffered or registered PC SDRAM
DIMM, 3.3V.
The CB64-ZX system board is
equipped with two 168-pin DIMM
(Dual In-line Memory Module)
sockets that support x64 unbuffered
PC SDRAM DIMM, 3.3V.
PC SDRAM (Synchronous Dynamic
Random Access Memory) uses a fast memory interface technology
that includes using the clock on the chip to synchronize with the
CPU clock so that the timing of the memory chips and the timing of
the CPU are synchronized. This saves time during transmission of
data, subsequently increasing system performance.

2.2.1 Installing the DIM Module
A DIM module simply snaps into a DIMM socket on the system
board. Pin 1 of the DIM module must correspond with Pin 1 of the
socket.

1. Pull the tabs which are at the ends of the socket to the side.
2. Position the DIMM above the socket with the notches in the
module aligned with the keys on the socket.
3. Seat the module vertically into the socket. Make sure it is
completely seated. The tabs will hold the DIMM in place.
2.3 DIP Switch Settings for Processors
(For Factory Use Only)
You can not overclock an Intel Celeronprocessor (PPGA) because
its frequency ratio is fixed by the manufacturer. The table on the next
page is for factory use only.
In the example above:
Switch 1: Off
Switch 2: On
Switch 3: Off
Switch 4: On

2.4 Jumper Settings for the CPUs Front Side Bus
Jumper JP2
CPUs Front Side Bus Select
The default setting of jumper JP2 is
Auto - the system will automatically
run according to the FSB of the
processor.The 100MHz setting (1-
2-3 Off) is reserved for future
100MHz FSB processors. Refer to
the figure on the next page.
Warning:
If your system is installed with
a 66MHz FSB processor, do
not move the jumper cap from
its default setting which is pins
1 and 2 On; otherwise your
system will not boot.

2.5 Jumper Settings for Clearing CMOS Data
Jumper JP3
Clear CMOS Data
If, for some reason, the CMOS data
becomes corrupted or you forgot the
supervisor/user/keyboard password,
the system can be reconfigured with
the default values stored in the ROM
BIOS. To load the default values,
power off your system and unplug
the power cord. Set JP3 pins 2 and
3 to On. Wait for a few seconds and
set JP3 back to its default setting,
pins 1 and 2 On. You may now plug
the power cord and power-on your
system.

Wake-On-Keyboard/Wake-On-Mouse
The system board supports the Wake-
On-Keyboard/Wake-On-Mouse
function.This function allows you to use
the keyboard or mouse to power-on
the system. By default, JP1 is disabled.
To use this function, set JP1 to 2-3 On.
Keyboard/Mouse Power On in the
Integrated Peripherals setup of the
Award BIOS must be set accordingly.
Refer to chapter 3 for details.
Warning:
1. If JP1 was previously enabled
with a password set in the
KB Power On Password field, and now you wish to disable
the Wake-On-Keyboard (password) function, make sure to
set the Keyboard/Mouse Power On field to Disabled prior
to setting JP1 to disabled. You will not be able to boot up
the system if you fail to do so.
2. The power button will not function once a keyboard
password has been set in the KB Power On Password
field of the Integrated Peripherals setup. You must type the
correct password to power-on the system.

2.7.2 PS/2 Mouse and Keyboard Ports
The PS/2 mouse port uses IRQ12. If a
mouse is not connected to this port, the
system will reserve IRQ12 for other
expansion cards.
Warning:
Make sure to turn off your
computer prior to connecting or
disconnecting a mouse or
keyboard. Failure to do so may
damage the system board.
