Award 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 Self­Test).

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

22

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.

36

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.

The Choice: 2, 3.

37

System BIOS Cacheable

Selecting Enabled allows caching of the system BIOS ROM at F0000h­FFFFFh, 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.

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.

4.13 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

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. Install CPU with Cooler

We provide a special designed cooler for the Wafer7850 CPU board.
There are two kind of installation directions which base on the CPU
package. If the CPU you would like to install is FCPGA package then
read the case one. If CPU is PPGA Celeron then start from case two.

Case one:
Step 1. Loose the four screws on the top of cooler about three rounds

screw

Step 2. To prevent form the CPU holders of the clip part interfere
with the other components those on the board. Make sure the two CPU
holder edges toward the left and right hand side.

Step 3. Make sure the pin-one marking on CPU toward the left hand
side. Push CPU lightly into the clip to make the CPU holder hold-

-ing the CPU base board then slowly tighten the screws.

Be careful, too tight would cause the CPU base board broken. Using
fingers to rotate the screws instead of screwdriver is recommended.
