Chapter II – Jumper Setting 2.1 Precautions Computer components and electronic circuit boards can be easily damaged by discharges of static electricity. Working on the computers that are still connected to a power supply can be extremely dangerous. Please make sure the guidelines below are followed to avoid damage to your computer or yourself:

Always disconnect the unit from the power outlet whenever you are working inside the chassis.

If possible, wear a grounded wrist strap when you are working inside the chassis. Alternatively, discharge any static

electricity by touching the bare metal chassis of the unit, or the bare metal body of any other grounded appliance.

Hold electronic circuit boards (such as BEX-220 board) by the edges only. Do not touch the components on the board

unless it is necessary to do so. Do not flex or stress the circuit board.

Leave all components in the static-proof package, which they were shipped with, until they are ready for installation.

Use correct screw and do not over drive the screw.


2.2 Jumper Settings A jumper is the simplest kind of electric switch consisting of two metal pins, which function as electrical contact points, in the form of a cap or plug. When setting the jumpers, ensure that the jumper caps are placed on the correct pins. When the jumper cap is placed on both pins, the jumper is short. If you remove the jumper cap, or place the jumper cap on just one pin, the jumper is open. Refer to the illustrations below for examples of what the 2-pin and 3-pin jumpers look like when they are short (on) and open (off). 2-Pin Jumper Open Short

3-Pin Jumper Pin-1 and Pin-2 are short

Chapter III – Installation This chapter shows you how to install Memory. 3.1 Installing and Removing Memory BEX-220 comes with 1x 200-pin SO-DIMM socket. To install the DDR modules: 1. Locate the memory slot on the board. 2. Hold the DDR module so that the key of the DDR module align with those on the memory slot. 3. Insert the module into the socket at a slight angle (approximately 30 degrees). Note that the

socket and module are both keyed, which means that the module can be installed only in one direction.

4. Apply firm and even pressure to each end of the module until you feel it was snapped down into the socket.

5. With the module properly seated in the socket, rotate the module downward. Continue pressing downward until the clips at each end lock into positions.

To remove the DDR module, press the clips with both hands.


Chapter IV – Configuring The BIOS Settings What you can configure

1. Hard drives, Diskette Drives, and Peripherals.

2. Video display types and display options.

3. Password protection against unauthorized use.

4. Power management features.

When do you need to access BIOS

1. System configuration needs to be changed.

2. System detects a configuration error and prompts a message

3. System clock needs to be updated.

4. Communication ports need to be re-defined.

5. System power management needs to be reconfigured.

6. System password needs to be reconfigured.

4.1 Entering The BIOS When the system is powered on, the BIOS will starts a Power-On Self Test (POST) routines. These routines perform

various diagnostic checks. If an error is detected, the error will be reported in two different ways:

If the error is detected before the display device is initiated, a series of beep sound will be transmitted.

If the error is detected after the display device is initiated, an error message will be prompted on the screen.

To enter the BIOS, please attach a PS/2 or USB keyboard on BEX-220 USB port, and press “DEL” key after BEX-220 is

powered on.

load the BIOS default values for the most stable, minimal-performance system operations.


4.11 Load Optimized Defaults Use this menu to load the BIOS default values that are factory settings for optimal performance system operations. While

Award has designed the custom BIOS to maximize performance, the factory has the right to change these defaults to meet

their needs. Press <Y> to load the default values setting for optimal performance system operations.


4.12 Set Password The User Password utility sets the password. The main board is shipped with the password disabled. If you want to change

the password, you must first enter the current password, and at the prompt enter your new password. The password is

case-sensitive. You can use up to eight alpha-numeric characters.

Press <Enter> after entering the password. At the next prompt, confirm the new password by retyping it and pressing

<Enter> again.

To disable, the password dialog box appears, and a message prompts confirming that the password has been disabled. If

you have set supervisor and user password, only the supervisor password allows you to enter the BIOS setup program.

Note: If you forget your password, the only way to solve this problem is to discharge the CMOS memory by turning power

off and placing a shunt (jumper cap) on jumper JP2 to short pin 2 and pin 3 for five seconds, then putting the shunt back to

pin 1 and pin 2 of JP2.


4.13 Save & Exit Setup Selecting this option and pressing <Enter> will save the new setting information in the CMOS memory and continue with

the booting process.

4.14 Exit Without Saving Selecting this option and pressing <Enter> will exit the Setup utility with-out recording any new values or changing old

ones.
