To clear CMOS, please follow the steps below:

1. Power off the system and unplug the chassis AC power cord.

2. Short JP1 at pin 2-3 for few seconds.

3. Set JP1 back to its Normal position at pin 1-2.

4. Plug the AC power cord to the chassis.

5. Power on the system and load the BIOS setup default.

JP2 Power On Mode

The mainboard supports two kinds of system power on mode, panel switch
power on (PAN SW. PWR ON) mode and keyboard power on (KB PWR ON)
mode. Set JP2 at pin 1-2 to use power switch/button to power on your system.

If you want to use the “Keyboard Power On” function, make sure you have a
300mA/+5VSB or above ATX power supply and the supporting mainboard
BIOS. Set JP2 at pin 2-3 to enable the keyboard power on mode.

Attach the ATX power button or suspend switch cable to this connector.
In the ATX power system, this connector will be not only an ATX power

button, but a suspend switch as well. Details are describes as below:
When the system is off, push the power button to turn the system on. When

the system is on, push the power button rapidly within 4 seconds to switch the
system to the suspend mode, and, by pushing and holding the button for
more than 4 seconds, it will turn the system completely off. When the system
is in the suspend mode, push the power button rapidly to turn the system on.

When the system is in suspend mode, the GRN LED will flash. And when the
system is in normal working mode, the GRN LED will not work.

2-3 System Memory Installation

There are 3 pcs 168-pin DIMM (Dual Inline Memory Module) sockets on the
mainboard which support Synchronous DRAM and Registered SDRAM, and
allow you install system memory maximum up to 768MB.

IBBP ATX Mainboard User’s Manual

<2-10>

II. HARDWARE INSTALLATION

2-3.1 Type

This mainboard supports Synchronous DRAM and Registered SDRAM.
However, mixing SDRAM and Registered SDRAM is not allowed. Install one
type only in your system for better compatibility.

2-3.2 Speed

The memory speed normally marked as: -15, -12, -10, -7, -8, PC-100.
The meaning is,

-15 = 15ns, and the maximum clock is 66MHz

-12 = 12ns, and the maximum clock is 83MHz

-10 = 10ns, and the maximum clock is 100MHz

-8 = 7ns, and the maximum clock is 125MHz

-7 = 8ns, and the maximum clock is 142MHz
PC-100 = New Intel specification for high memory speed
with 100MHz or above CPU Bus Clock.
This motherboard supports all the above memory speed. For better system

performance and reliability, we suggest that you use PC-100 SDRAM if
100MHz or above CPU Bus Clock is used in your system.

2-3.3 Buffered and Non-buffered

Only the non-buffered DIMM can be used in this mainboard.

The difference between buffered and non-buffered DIMM can be identified by
the notch position shown above.

II. HARDWARE INSTALLATION

2-3.4 2-clock and 4-clock signal

Both 2-clock and 4-clock SDRAM DIMM supported by this mainboard.

2-3.5 Parity and Non-parity

This mainboard supports standard 64 bit (Non-parity) and 72 bit (Parity)
DIMM modules.

2-3.6 Memory Auto detection by BIOS

This mainboard BIOS can automatically detect the DIMM memory size and
type, so you do not need to adjust any hardware or software settings. The
maximum memory size supported up to 768MB.

2-3.7 Suggested SDRAM combination

This mainboard supports the following SDRAM combination.

DIMM Location

DIMM 1 SDRAM 8, 16, 32, 64 128,

DIMM 2 SDRAM 8, 16, 32, 64 128,
