BIOS Setup

4.1 Introduction

This chapter discusses the Setup program built into the BIOS. The
Setup program allows users to configure the system. This
configuration is then stored in battery-backed CMOS RAM so that it
retains the Setup information while the power is off.

4.2 Starting Setup

The BIOS is immediately active when you turn on the computer. While
the BIOS is in control, the Setup program can be activated in one of
two ways:

1. By pressing <Del> immediately after switching the system on, or

2. by pressing the <Del> key when the following message appears
briefly at the bottom of the screen during the POST (Power On
Self-Test).

Press DEL to enter SETUP.

If the message disappears before you respond and you still wish to
enter Setup, restart the system to try again by turning it OFF then ON
or pressing the "RESET" button on the system case. You may also
restart by simultaneously pressing <Ctrl>, <Alt>, and <Delete> keys.
If you do not press the keys at the correct time and the system does
not boot, an error message will be displayed and you will again be
asked to...

PRESS F1 TO CONTINUE, DEL TO ENTER SETUP

20

4.3 Using Setup

In general, you can use the arrow keys to highlight items, press
<Enter> to select, use the PageUp and PageDown keys to change
entries, press <F1> for help and press <Esc> to quit. The following
table provides more details about how to navigate in the Setup
program using the keyboard.

Menu Level 

This section allows you to configure the system based on the specific
features of the installed chipset. This chipset manages 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. It must be stated that these
items should never need to be altered. The default settings have been
chosen because they provide the best operating conditions for your
system.

34

DRAM Settings

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 had 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.

SDRAM CAS Latency Time

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

The Choice: 2, 3

SDRAM Cycle Time Tras/Trc

Select the number of SCLKs for an access cycle.

The Choice: 5/7, 6/8.

SDRAM RAS-to-CAS Delay

This field lets you insert a timing delay between the CAS and RAS
strobe signals, used when DRAM is written 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 Choice: 2, 3.

SDRAM RAS Precharge Time

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.

35

The Choice: 2, 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 choice: Enabled, Disabled.

Video BIOS Cacheable

Select Enabled allows caching of the video BIOS , resulting in better
system performance. However, if any program writes to this memory
area, a system error may result.

The Choice: Enabled, Disabled.

Memory Hole At 15M-16M

You can reserve this area of system memory for ISA adapter ROM.
When this area is reserved, it cannot be cached. The user information
of peripherals that need to use this area of system memory usually
discusses their memory requirements.

The Choice: Enabled, Disabled.

CPU Latency Timer

Enabled :CPU cycle will only be Deferred after in has been in a
“Snoop Stall” for 31 clocks and another ADS# has arrived.

Disabled: CPU cycle will only be Deferred immediately after the
GMCH receives another ADS#.

The Choice: Enabled, Disabled.

36

Delay Transaction

The chipset has an embedded 32-bit posted write buffer to support
delay transactions cycles. Select Enabled to support compliance with
PCI specification version 2.1.

The Choice: Enabled, Disabled.

Onboard VGA

This item controls the Onaboard VGA to enabled or disabled.

4.14 Supervisor/User Password Setting

You can set either supervisor or user password, or both of then. The
differences between are:

supervisor password :
can enter and change the options of the setup menus.

user password :
just can only enter but do not have the right to change the options of
the setup menus. When you select this function, the following
message will appear at the center of the screen to assist you in
creating a password.

ENTER PASSWORD:

Type the password, up to eight characters in length, and press
<Enter>. The password typed now will clear any previously entered
password from CMOS memory. You will be asked to confirm the
password. Type the password again and press <Enter>. You may
also press <Esc> to abort the selection and not enter a password.

To disable a password, just press <Enter> when you are prompted to
enter the password. A message will confirm the password will be
disabled. Once the password is disabled, the system will boot and
you can enter Setup freely.

PASSWORD DISABLED.

When a password has been enabled, you will be prompted to enter it
every time you try to enter Setup. This prevents an unauthorized
person from changing any part of your system configuration.

Additionally, when a password is enabled, you can also require the
BIOS to request a password every time your system is rebooted. This
would prevent unauthorized use of your computer.

You determine when the password is required within the BIOS
Features Setup Menu and its Security option (see Section 3). If the
Security option is set to password will be required both at boot and at
entry to Setup. If set to “Setup”, prompting only occurs when trying to
enter Setup.

Pressing “Y” stores the selections made in the menus in
CMOS – a special section of memory that stays on after you
turn your system off. The next time you boot your computer,
the BIOS configures your system according to the Setup
selections stored in CMOS. After saving the values the system
is restarted again.

Exit Without Saving

Pressing <Enter> on this item asks for confirmation:

Quit without saving (Y/N)? Y

This allows you to exit Setup without storing in CMOS any
change. The previous selections remain in effect. This exits
the Setup utility and restarts your computer.

Appendix A. WatchDog Timer

The WatchDog Timer is provided to ensure that standalone
systems can always recover from catastrophic conditions that
cause the CPU to crash. This condition may have occurred by
external EMI or a software bug. When the CPU stops working
correctly, hardware on the board will either perform a
hardware reset (cold boot) or a Non-Maskable Interrupt (NMI)
to bring the system back to a known state.

A BIOS function call (INT 15H) is used to control the
WatchDog Timer:

INT 15H:

AH – 6FH

Sub-function:

AL – 2 : Set the Watchdog Timer’s period
BL : Time-out value(Its unit--second or minute, is
dependent on the item “WatchDog Timer unit

select” in CMOS setup).

You have to call sub-function 2 to set the time-out period of
Watchdog Timer first. If the time-out value is not zero, the
Watchdog Timer will start counting down. While the timer
value reaches zero, the system will reset. To ensure that this
reset condition does not occur, the WatchDog Timer must be
periodically refreshed by calling sub-function 2. However the
Watchdog timer will be disabled if you set the time-out value
to be zero.

A tolerance of at least 10% must be maintained to avoid
unknown routines within the operating system (DOS),
such as disk I/O that can be very time-consuming.

Note: when exiting a program it is necessary to disable the

WatchDog Timer, otherwise the system will reset.

Appendix C. ATX Power Supply

The following notes show how to connect ATX Power Supply to the
backplanes and / or the ISBC card.

A. For backplanes with ATX Connector

1. Please, disconnect the AC cord of the Power Supply from the AC
source to prevent sudden electric surge to the board.

2. Please, check the type of your CPU board. All CPU board listed
on the next page support ATX power supply but has two types of
power switch connection:

2.1. PSB-810EAV (through Power Button & GND):

Connect the ATX power button switch to the pin 17 (power
button) and pin 19 (+5VSB) of CN19 on the board. And
connect the power cable from CN4 of backplane to CN2 of
CPU card.

If you want to turn ON the system, just press the button once.
And If you want to turn off the power supply, please press the
ATX power switch button for about 4 seconds.

57

B. For the backplanes with ATX power supply

connector

For some SBC without ATX power ON/OFF function, then you
can control the ATX power supply through backplane’s PS ON
connector. Refer to the figure below: for the backplanes with ATX
connector, the connection can be made simply as following:

1. Connect the ON/OFF (ordinary one) switch to Pin 2 (PS ON) and
Pin 3 (GND) of connector CN2

2. You may now turn the power ON/OFF by the power switch

Note

If you have used ATX power supply, and want to change to
AT power supply, you must clear CMOS data(JP7). Otherwise
the board may could not work while applying the AT power
supply to it.

Appendix D. PSB-810EAV With Intel82559 LAN

Chip

The PSB-810EAV With Intel82559 provides two kind of Wake
Up functions. This page describes how to use Modem Wake-Up and
LAN Wake-Up function.

Wake-Up function is working while you use ATX power supply.

Wake-Up By Modem Ring On(All versions of PSB­810EAV):

You must set the option Power On By Ring of CMOS SETUP to
be enabled. The ATX power supply will be switched on when there
is a ring signal detected on pin “RI” of serial port.

Wake-Up On LAN(Intel 82559 Only):
When your computer is in power-down status, you can see LAN
Link/Active LED is flashing. This status indicates that the LAN chip
has entered standby mode and waits for Wake-Up signal. You can
use other computers to wake up your computer by sending ID to it.

: ID is the address of your system LAN. Every LAN chip has a

ID
factory set ID which you can find it from network information in
WINDOWS.

ID’s format is xx-xx-xx-xx-xx-xx

Example ID: 00905C21D4
