Jumper Setting

This chapter of the User’s Manual describes how to set jumpers.

2.1 Before You Begin

Ensure you have a stable, clean working environment. Dust and dirt can get into components and cause a

malfunction. Use containers to keep small components separated.

Adequate lighting and proper tools can prevent you from accidentally damaging the internal components.

Most of the procedures that follow require only a few simple tools, including the following:

 A Philips screwdriver  A flat-tipped screwdriver  A set of jewelers screwdrivers  A grounding strap  An anti-static pad

Using your fingers can disconnect most of the connections. It is recommended that you do not use needle-

nosed pliers to disconnect connections as these can damage the soft metal or plastic parts of the connectors.

Before working on internal components, make sure that the power is off. Ground yourself before touching

any internal components, by touching a metal object. Static electricity can damage many of the electronic

components. Humid environment tend to have less static electricity than dry environments. A grounding

strap is warranted whenever danger of static electricity exists.

2.2 Precautions

Computer components and electronic circuit boards can be damaged by discharges of static electricity.

Working on the computers that are still connected to a power supply can be extremely dangerous. Follow the

guidelines below to avoid damage to your computer or yourself:

 Always disconnect the unit from the power outlet whenever you are working inside the case.  If possible, wear a grounded wrist strap when you are working inside the computer case. Alternatively,

discharge any static electricity by touching the bare metal chassis of the unit case, or the bare metal

body of any other grounded appliance.

 Hold electronic circuit boards (such as the EBC575 board) by the edges only. Do not touch the

components on the board unless it is necessary to do so. Don’t flex or stress the circuit board.

 Leave all components inside the static-proof packaging that they shipped with until they are ready for

installation.

 Use correct screws and do not over tighten screws.

2.3 Setting Jumpers

A jumper is the simplest kind of electric switch. It consists of two metal pins and a cap. 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. Please see the following illustrations:

The illustrations on the right show

a 2-pin jumper. 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.

These illustrations show a 3-pin

jumper. Pins 1 and 2 are SHORT.

3.4 Change CPU

To change the CPU:

1. Pull the handling bar of the socket upward to the other end to loosen the socket’s openings. Carefully lift

the existing CPU up to remove it from the socket.

2. Place the new CPU on the middle of the socket, orienting its beveled corner to line up with the socket’s

beveled corner. Make sure the pins of the CPU fit evenly to the socket openings. Replace the handling bar to

fasten the CPU to the socket.

Figure 3-7: How to Change CPU

25 Chapter 3EBC575 User’s Manual

3.5 Installing the Fan Heatsink

Use the following instructions for installing the fan heatsink:

1. The heatsink has a thermal interface material attached to the bottom, shown in Figure 3-10. Do not

damage the thermal interface material while installing.

2. Align the fan heatsink and slip assembly (A in Figure 3-9) with the retention mechanism (the fan heatsink

is symmetrical) and place it on the processor (as shown in Figure 3-10). Allow the heatsink base to compress

(without rotating or twisting) the thermal interface material over the surface of the processor’s integrated heat

spreader.

3. With the clip levers (C in Figure 3-9) in the upward position, push down on all four clip frame corners (D in

Figure 3-9) to secure the clip frame latches (E in Figure 3-9) to the retention mechanism hooks (F in Figure

3-9), as shown in Figure 3-11.

Note: Make sure the processor fan cable is free from any obstruction and is not trapped under slip frame (B

in Figure 3-9)

4. Close the clips levers in the opposite direction, one at a time (levers require force to be completely closed),

as shown in Figure 3-12a, in the same time, hold the topside of th fan heatsink with your other hand, please

refer to Figure 3-12b.

Note: It is important to prohibit the heatsink from rotate or twist on the processor’s integrated heat spreader.

Securing the fan heatsink while closing the clip levers will prevent the thermal interface material from

damage and the processor will operate correctly.

5. Close the clip lever (2 in Figure 3-12c), while holding the topside of the fan heatsink with your other hand

(B in Figure 3-12c).

6. Once the clip levers are closed, verify that the heatsink is securely retained and that the clip frame latches

are properly engaged with the retention mechanism hooks.

7. Lastly, connect the processor fan cable to the motherboard fan power header (Figure 3-13). Consult the

motherboard manual to determine the correct fan header to use.

Award BIOS Setup

This chapter explains how to use the BIOS Setup program for the EBC 575. The current BIOS setup pictures

in the chapter is for reference only, which may change by the BIOS modification in the future. User can

download any major updated items or reversion from NEXCOM web site http://www.nexcom.com.tw. If any

unclear message occurs, please contact NEXCOM customer service representative for help or log onto

http://www.nexcom.com.tw/contact/contact.htm.

4.1 About the BIOS

The BIOS (Basic Input and Output System) Setup program is a menu driven utility that enables you to make

changes to the system configuration and tailor your system to suit your individual work needs. It is a ROM-

based configuration utility that displays the system’s configuration status and provides you with a tool to set

system parameters. These parameters are stored in non-volatile battery-backed-up CMOS RAM that saves

this information even when the power is turned off. When the system is turned back on, the system is

configured with the values found in CMOS.

With easy-to-use pull down menus, you can configure such items as:

 Hard drives, diskette drives, and peripherals  Video display type and display options  Password protection from unauthorized use  Power management features

The settings made in the Setup program intimately affect how the computer performs. It is important, therefore,

first try to understand all the Setup options, and second, to make settings appropriate for the way you use the

computer.

4.2 When to Run BIOS

This program should be executed under the following conditions:

 When changing the system configuration  When a configuration error is detected by the system and you are prompted to make changes to the

Setup program

appear when anything attempts to access the boot sector or hard disk partition table:

! WARNING !

Disk boot sector is to be modified

Type “Y” to accept write or “N” to abort write

Award Software, Inc.

 Disabled: No warning message will appear when an attempt is made to access the boot sector or hard

disk partition table.

Note: This function is available only for DOS and other operating systems that do not trap INT13. For

complete protection against viruses, install virus software in your operating system and update the

virus definitions regularly.

Many disk diagnostic programs that access the boot sector table can trigger the virus warning message.

If you plan to run such a program, we recommend that you disable the virus warning.

CPU L1 & L2 Cache

Cache memory is additional memory that is much faster than conventional DRAM (system memory). This

BIOS feature is used to enable or disable the processor’s Level 1 and Level 2 cache. Naturally, the default

and recommended setting is Enabled.

Hyper Threading Technology

The Intel Hyper-Threading Technology allows a single processor to execute two or more separate threads

concurrently. When hyper-threading is enabled, multi-threaded software applications can execute their threads

in parallel, thereby improving the processor’s performance.

Quick Power-On Self-Test

Select Enabled to reduce the amount of time required to run the Power-On Self-Test (POST). A quick POST

skips certain steps. We recommend that you normally enable quick POST.

entered at the prompt.

 Setup: The system will boot, but access to Setup will be denied if the correct password is not entered

at setup.

APIC Mode

The APIC Mode BIOS feature is used to enable or disable the motherboard’s APIC (Advanced Program-

mable Interrupt Controller). If your single-processor motherboard supports APIC and you are using a Win32

operating system (Windows NT, 2000 and XP), it’s recommended that you enable this feature to allow faster

and better IRQ handling. If you are using a multiprocessor motherboard, you must enable this feature be-

cause it’s required for IRQ handling in multiprocessor systems.

MPS Version Control for OS

This feature is only applicable to multiprocessor motherboards as it specifies the version of the Multi-Proces-

sor Specification (MPS) that the motherboard will use. The MPS is a specification by which PC manufactur-

ers design and build Intel architecture systems with two or more processors.

MPS version 1.4 is required for a motherboard to support a bridgeless secondary PCI bus.

OS Select for DRAM>64MB

Set to OS2 if the system memory size is greater than 64 MB and the operating system is OS/2, otherwise

select Non-OS2 option.

4.9 Advanced Chipset Features

Since the features in this section are related to the chipset in the CPU board and all are optimized, you are not

recommended to change the default settings in the setup table, unless you understand the chipset features.

This section allows you to configure the system based on the specific features of the installed chipset. This

chipset manage bus speeds and access to system memory resources, such as DRAM and the external

cache. It also coordinates communications between the conventional ISA bus and the PCI bus. The default

settings have been chosen because they provide the best operating conditions for your system. The only

time you might consider making any changes would be if you discovered that data was being lost while using

your system.

The first chipset settings deal with CPU access to dynamic random access memory (DRAM). The default

timings have been carefully chosen and should only be altered if data is being lost. Such a scenario might

well occur if your system has mixed speed DRAM chips installed so that greater delays may be required to

preserve the integrity of the data held in the slower memory chips.

Selecting Advanced Chipset Features on the main program screen displays this menu:

40 Chapter 4EBC575 User’s Manual

Figure 4-5: BIOS – Advanced Chipset Features

DRAM Timing Selectable

The choices are: Manual, and By SPD. The option “By SPD” enables the system to automatically set the

SDRAM timing by Serial Presence Detect (SPD). SPD is an EEPROM chip on the DIMM module that stores

information about the memory chips it contains, including size, speed, voltage, row and column addresses,

and manufacturer. Select “Manual” allows users manually set the following four timing parameters for the

system memory.

CAS Latency Time

When synchronous DRAM is installed, the number of clock cycles of CAS latency depends on the DRAM

timing. Do not reset this field from the default value specified by the system designer. The choices are: 1.5,

to, read from, or refreshed. Fast gives faster performance; and slow gives more stable performance. This

field applies only when synchronous DRAM is installed in the system. The choices are: 2, 3.

DRAM RAS# Precharge

If an insufficient number of cycles is allowed for the RAS to accumulate its charge before DRAM refresh, the

refresh may be incomplete and the DRAM may fail to retain data. Fast gives faster performance; and Slow

gives more stable performance. This field applies only when synchronous DRAM is installed in the system.

The choices are 2 and 3.

System BIOS cacheable

Selecting Enabled allows caching of the system BIOS ROM at F0000h-FFFFFh, resulting in better system

performance. However, if any program writes to this memory area, a system error may result. The available

choices are Enabled, Disabled.

HDD Power Down

After the selected period of drive inactivity, the hard disk drive powers down while all other devices remain

active.

Wake-Up by Onboard LAN/PCI

When the system enters a Soft-off mode (Standby power exist but system is not working), it will wake up

system when specific signals occurred. The BIOS monitors the system for “activity” to determine when to

enable power management.

If you enable this feature, the computer specifies that any signal noticed on the LAN and PCI (Peripheral

Component Interconnect) bus channel must make go out from the hibernation state. The choices: Enabled,

Disabled.

Power On by Ring

An input signal on the serial Ring Indicator (RI) line (in other words, an incoming call on the modem) awakens

the system from a soft off state. The choices: Enabled, Disabled.

Resume by Alarm

When enabled, you can set the data and time at which the RTC (real-time clock) alarm awakens the system

from Suspend mode. The choices are Enabled, and Disabled. If you enabled this function, set the date and

time for the followings.

assigned to PCI devices in the chosen slot. Options available: Auto, 3, 4, 5, 7, 9, 10, 11, 12, 14 and 15.

Memory Resource

Memory length can be reserved as 8 KB, 16 KB, 32 KB or 64 KB and its address can be selected from C800

to DC00. Reserved memory address can not be modified when "Resource Controlled" is Auto.

PCI/VGA Palette Snoop

This setting is used only to solve the visualization problems with dedicated MPEG decompression cards. In

such specific case, setup the voice on Enabled to allow the BIOS to monitor the visualization passages

between the principal card and the card of decodes. The default setting is Disabled.

Assign IRQ for VGA

Enable this setting assigns an IRQ channel to the graphic card, allows the revival of the system from a

hibernation state when activity is noticed on the graphic card. If you are not using your system’s VGA controller,

select Disabled to free the IRQ resource.

Assign IRQ for USB

Select Enabled if your system has a USB controller and you have one or more USB devices connected. If you

are not using your systems USB controller, select Disabled to free the IRQ resource.

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.

4.17 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.

4.18 Exit Without Saving

Appendix B Watchdog Timer Setting

The EBC575 series features a watchdog timer that reset the CPU or generates an interrupt if the processor

stops operating for any reason. This feature ensures system reliability in industrial standalone or unmanned

environments.

B.1 Watchdog Timer Working Procedure

The Watchdog Timer (WDT) is a special hardware device that monitors the computer system during normal

operation. The WDT has a clock circuit that times down from a set number to zero. If a monitored item occurs

before the timer reaches zero, the WDT resets and counts down again. If for some reason the monitored

item doesn’t occur before the timer reaches zero, the WDT performs an action, such as a diagnostic opera-

tion (rebooting the computer) or generate an NMI.

You must enter timer values into the WDT Configuration Register (Write the control value to the Configura-

tion Port), and clear (read the Configuration Port).

WDT Configuration Port F2 Default at F2

B.2 Watchdog Timer Control Register

The Watchdog Timer Control Register controls the EDT working mode. Write the value to the WDT Configu-

ration Port.

The following table describes the Control Register bit definition.

Table B-2: Control Register Bit Definition

B.3 Watch Dog Timer Programming Procedure

Power on or reset the system

The initial value of WDT Control Register (D4~D0) is zero, when power is on or reset the system. The

following shows the initial value of WDT (00000000b):

Bit Value Mean

4 0 Select Reset

Table B-3: WDT Control Register Initial Value

76 Appendix BEBC575 User’s Manual

Initialize the SQW of RTC (set SQW output period = 0.5 second)

To initialize the SQW of RTC processor is to set the SQW signal which is output period = 0.5 second. It offers

the basic frequency of the WDT counter.

The following is an example of initializing the SQW signal program in Intel 8086 assembly language.

; (General SQW = 0.5 Sec.)

Mov dx, 70h

Mov ax, 0Ah

Out dx, al ; Out port 70h = 0Ah

Mov dx 71h

Mov as 2Fh

Out dx, al ; Out port 71h = 2Fh

; (enable the SQW output)

Mov dx, 70h

Mov ax, 0Bh

Out dx, al ; Out port 70h = 0Bh

Mov dx, 71h

Mov ax, 0Ah

Out dx, al ; Out port 71h = 0Ah

Clear the WDT

Repeatedly read WDT Configuration Port and the interval cannot be longer than the preset time, otherwise,

the WDT will generate NMI or Reset signal for the system. The following is an example of clear the WDT

program in Intel 8086 assembly language.

; (Clear the WDT)

Mov dx, F2h ; Setting the WDT configuration port

In al, dx

Note: Before running WDT, you must clear WDT working mode. The initial value of WDT Control Register

is shown as follows:.

WDT Control Register (Write to WDT configuration port)

You can set the WDT Control Register to control the WDT working mode.

The initial value of the WDT Control Register is as the following:

; Setting the WDT Control Register as AL

Mov al, 0h ; Setting initial value = 0 for the WDT Control

77 Appendix BEBC575 User’s Manual

Follow these instructions below to set the register:

1. Select the time-out intervals of WDT (decide the values of D2, D1, D0 in F2)

Exampe: If D2~D0 = 0, the time-out internal is 64 seconds.

AND al, 11111000b ; Setting the time-out internal as 64 seconds.

2. Enable or Disable WDT (decide D3 value in F2)

Example: D3 = 0, Disables WDT

OR al, 11110111b ; Disable the WDT

Example: D3 = 1, Enables WDT

OR al, 00001000b ; Enable the WDT

After finishing the above setting, you must be output for the Control Register’s value to the WDT Configura-

tion Port. Then WDT will start according to the above setting.

MOV dx, F2h ; Setting WDT Configuration Port

OUT dx, al ; Output the Control Register Value
