2.2 CPU INSTALLING AND UPGRADING

To upgrade to a higher power CPU, simply remove the old CPU and install the new one;
be sure to set the jumpers for the new CPU type and speed.

WARNING!

Disconnect the power cord from your system when you intend to work on it or

you plan to open the chassis of your IPC. Do not make connections when the
power is turned on, the sensitive electronic components could be damaged
by the sudden rush of power. Please only allow experienced electronics
technicians to do this job.

STATIC ELECTRICITY
PRECAUTION!

Caution! Computer components are very sensitive to damage from static
electric discharge. Always ground yourself to remove static charge build-up
before touching the boards in the computer. Use a grounding wrist strap at

all times. Place all electronic components on the anti-static pad for static-

dissipation or in a static-shielded bag when they are not in the chassis.

2.3 JUMPER SETTING OVERVIEW

In order to select the operation modes of your system, configure and set the jumpers on
the your MB to match the need of your application. To set a jumper, a plastic cap
containing metal contacts is placed over the jumper pins as designated by the required
configuration as listed in this section. A jumper is said to be “ on ” or “ 1-2 ” when the
black cap has been placed on two of its pins, as show in the figure below:

A pair of needle-nose pliers is recommended when working with jumpers. If you have
any doubts about the best hardware configuration for your application, contact your local
sales representative before you make any changes. In general, you simply need a
standard cable or jumper to make most connections.

CHAPTER 3.
AWARD BIOS SETUP

The Basic Input / Output System (BIOS) is a program that takes care of the basic level of
communication between the processor and peripherals. In addition, the BIOS also
contains codes for various advanced features found in the system board. Award' s ROM
BIOS provides a built-in Setup program that allows user to modify the basic system
configuration and settings. The modified data will be stored in a battery-backed CMOS
RAM so that the data will be retained even when the power is turned off. In general,
the information saved in the CMOS RAM stay unchanged unless there is configuration
change in the system, such as hard drive replacement or new equipment is installed.

3.1 RUNNING AWARD BIOS

The Setup Utility is stored in the BIOS ROM. When the power of the computer system
is turned on, a screen message appears to give you an opportunity to call up the Setup
Utility; while the BIOS will enter the Power On Self Test (POST) routines. The POST
routines perform various diagnostic checks while initializing the board hardware. If the
routines encounter an error during the tests, the error will be reported in either of the two
different ways, you may hear a series of short beeps or see an error message on the
screen display. There are two kinds of error: fatal or non-fatal. The system can
usually continue to boot up sequence with the non-fatal errors. Non-fatal error
messages usually appear on the screen along with the following instructions:

“ Press <F1> to RESUME ”

Write down the message and press the F1 key to continue the boot up sequence. After
the POST routines are completed, the following message appears:

“ Press DEL to enter SETUP ”

Entering Setup

Turn on the power of the computer system and press <Del> immediately. If you don’ t
have the chance to respond, reset the system by simultaneously typing the <Ctrl>, <Alt>
and <Delete> keys, or by pushing the ‘ Reset ’ button on the system cabinet. You can
also restart by turning the system OFF then ON.

The Standard CMOS Setup utility is used to configure the following components such as
date, time, hard disk drive, floppy drive, display, and memory. Once a field is
highlighted, on-line help information is displayed in the left bottom of the Menu screen.

Set Date : Month, Date, Year.

Set Time : Hour, Minute and Second. Use 24 Hour clock format (for p.m. time, add 12

to the hour number, you would enter 4:30p.m. as 16:30).

BIOS SETUP

TF-486 / 26

Hard Disks : There are four hard disks listed: “Primary Master”, “Primary Slave”,
“Secondary Master” and “Secondary Slave”. For each IDE channel, the first device is
the “Master” and the second device is “Slave”. Hard disk types from 1 to 45 are the
standard ones. To select or change the configuration, move the cursor to the desired
position and press <Page Up> or <Page Down> to change the option : (1) Press “Auto”
for IDE HDD auto detection, (2) Press “User” for user definable, and Press “None” for not
installed (e.g. SCSI). There are six categories of information that you must enter for a
HDD: “CYLS.” for (number of cylinders), “HEADS” for (number of heads), “PRECOMP”
for (write pre-compensation), “LANDZ” for (landing zone), “SECTOR” for (number of
sectors) and ”MODE“ for (Normal, LBA, LARGE and AUTO). The hard disk vendor‘ s or
system manufacturer’ s documentation should provide you with the drive specifications.
For an IDE hard drive, you can set “TYPE” to “Auto” or use the “IDE HDD AUTO
DETECTION” utility in the main program screen to enter the drive specifications.

Here is a brief explanation of drive specifications:
l Type : The BIOS contains a table of pre-defined drive types. Each defined

drive type has specified number of cylinders, number of heads, write compensation
factor, landing zone, and number of sectors. Drives whose specifications do not
accommodate any pre-defined type are classified as type USER.

l Size : Disk drive capacity (approximate). Note that this size is usually slightly

greater than the size of a formatted disk given by a disk checking program.

l Cyls : Number of cylinders.
l Head : Number of heads.
l Precomp : Write pre-compensation cylinder
l Landz : Landing zone.
l Sector : Number of sectors.
l Mode : Auto, Normal, Large, or LBA.

• Auto: The BIOS automatically determines the optimal mode.

• Normal: Maximum number of cylinders, heads, and sectors supported are 1024,

16, and 63.

• Large: For drives that do not support LBA and have more than 1024 cylinders.

• LBA (Logical Block Addressing): During drive accesses, the IDE controller

transforms that data address described by sector, head, and cylinder number
into physical block address, significantly improving data transfer rates. For
drives that greater 1024 cylinders.

BIOS SETUP

TF-486 / 27

There are four hard disks listed: “Primary Master”, “Primary Slave”, “Secondary Master”
and “Secondary Slave”. For each IDE channel, the first device is the “Master” and the
second device is “Slave”. Hard disk types from 1 to 45 are the standard one. To
select or change the configuration, move the cursor to the desired position and press
<Page Up> or <Page Down> to change the option.

The AWARD BIOS supports three HDD modes: NORMAL, LBA and LARGE.

NORMAL mode : This is a Generic Access mode in which neither the BIOS nor the IDE
controller will make any transformation during the accession. The maximum HDD size
is supported by the NORMAL mode that is 528 Megabytes.

LBA mode : This is a Logical Block Addressing mode which is a HDD accessing method
to overcome the 528 Megabytes restriction. The number of cylinders, heads and
sectors that are shown in setup may not be the physical number contained in the HDD.

During the HDD accessing, the IDE controller will transform the logical address that is
described by the cylinder, head and sector numbers into its own physical address as
contained inside the HDD. The maximum HDD size that is supported by the LBA mode
is 8.4 Gigabytes.

LARGE mode : Some IDE HDD contains more than 1024 cylinders without the LBA
support. This access mode tricks DOS (or other OS) with the number of cylinders that
is less than 1024 by dividing it by 2. At the same time, the number of heads is multiplied
by 2. A reverse transformation process will be made inside INT13H in order to access
to the right HDD address. The maximum HDD size that is supported by the LARGE
mode is 1 Gigabytes.

Note : 1. To support LBA or LARGE mode, there are softwares located in the AWARD

HD Service Routine“INT13H”. It may fail to access a HDD with LBA or
LARGE modes selected if you are running under an Operating System that
replaces the whole INT13H service routine.

2. Entering incorrect drive specifications will result in a hard disk drive that will
function improperly or no function at all.

Memory : You cannot change any values in the Memory fields; they are only for your
information. The fields show the total installed random access memory (RAM) and
amounts allocated to base memory, extended memory, and other (high) memory. RAM
is counted in kilobytes (KB: approximately one thousand bytes) and megabytes (MB:
approximately one million bytes).

RAM is the computer’ s working memory, where the computer stores programs and data
currently being used, so they are accessible to the CPU. Modern personal computers
may contain up to 64MB, 128MB, or more.
l Base Memory : Typically 640KB. Also called conventional memory. The DOS

operating system and conventional applications use this area.

l Extended Memory : Above the 1-MB boundary. Early IBM personal computers

could not use memory above 1MB, but current PCs and their software can use
extended memory.

l Other Memory : Between 640KB and 1MB; called High memory. DOS may load

terminate-and-stay-resident (TSR) programs, such as device drivers, in this area, to
free as much conventional memory as possible for applications. Lines in your
CONFIG.SYS file that start with LOADHIGH load programs into high memory.

The following explains the options for each of the features as listed in the above menu:

Virus Warning : The default setting of the Virus Warning is “Disabled”. When it is
enabled, any attempt to write the boot sector and partition table will halt the system and
cause a warning message to appear. If this happens, you can use an anti-virus utility
on a virus free, bootable floppy diskette to reboot, to clean and to investigate your
system.

BIOS SETUP

TF-486 / 31

CPU Internal Cache : The default setting is “Enabled”. This setting enables the CPU
internal cache.

External Cache : The default setting is “Enabled”. This setting enables the external
cache.

Quick Power On Self Test : The default setting is “Enabled”. This speeds up the
Power On Self Test (POST) by skipping some items that are normally checked during the
full POST. If your system is functioning normally, you can choose this feature to speed
the booting process.

Boot Sequence : The default setting is “A:,C SCSI”; the other options are “C,A,SCSI”;
“C,CDROM,A”; “CDROM,C,A”; “D,A,SCSI”; “E,A,SCSI”; “F,A,SCSI”; “SCSI,A,C”;
“SCSI,C,A”; “C only”; and “LS/ZIP,C”. This setting determines where the computer
looks first for an operating system, the hard disk, or the floppy disk, … or other. The
BIOS will load the operating system from the disk drives in the sequence as selected
here.

Swap Floppy Drive : The default setting is “Disabled”. This setting gives you an option
to swap A and B floppy disks. Normally, the floppy drive A is the one at the end of the
cable and drive B is at the other end. If you set this option to “Enabled”, the Drive A will
function as Drive B, and vice-versa under the DOS.

Boot Up Floppy Seek : The defaults setting is “Disabled”. When enabled, the BIOS
will check whether there is a floppy disk drive installed.

Boot Up Numlock Status : The default setting is “On”. If set “Off”, the cursor controls
will function on the numeric keypad.

Boot Up System Speed : The default setting is “High”. This sets the CPU speed at boot
up.

Gate A20 Option : The default setting is “Fast”. This is the optimal setting for the CPU
card. The other option is “Normal”.

Typematic Rate Setting : The default setting is “Disabled”. If enabled, you can set the
typematic rate and typematic delay.

BIOS SETUP

TF-486 / 32

Typematic Rate (Chars/Sec) : This setting controls the speed at which the system
registers the repeated keystrokes. The choices range from 6 to 30 Chars/Sec. The
default setting is “6” Chars/Sec.

Typematic Delay (Msec) : This setting controls the time between the display of the first
and second characters. There are four delay choices: 250ms, 500ms, 750ms and
1000ms. The default setting is “250” ms.

Security Option : This setting controls the password in the main screen. The options
are “Setup” and “System”. Select “Setup” and it will protect the Setup Utility settings
from being tampered with. Select “System” if you want to use password feature every
time the system boots up. The default setting is “Setup”. You can create your password
by using the “SUPERVISOR/USER PASSWORD” utility on the main program screen.

PCI/VGA Palette Snoop : The default setting is “Disabled”. Set to “Enable” if any ISA
adapter card installed requires VGA palette snooping.

OS Select For DRAM > 64MB : The default setting is “Non-OS2”. Set to “OS2” if the
system memory size is greater than 64MB and the operating system is OS/2.

Video BIOS Shadow : The default setting is “Enabled” which will copy the VGA display
card BIOS into system DRAM to improve performance.

C8000-CFFFF Shadow to D8000-DFFFF Shadow : The default setting for the shadow
feature is “Disabled”. When enabled, the ROM with the specific address is copied into
system DRAM. It will also reduce the size of memory available to the system. After
you have made your selection in the BIOS FEATURES SETUP, press the <ESC> key to

environment.

Auto Configuration : The default setting is “Enabled” which will optimize DRAM timing
automatically depending on whether the DRAM used is either 70ns or 60ns. The other
option is “Disabled” which allows you to change DRAM timing manually.

BIOS SETUP

TF-486 / 34

AT-BUS Clock : You can set the speed of the AT bus in terms of the CPU clock speed,
or at the fixed speeds of 7.16M Hz.

DRAM Read / Write Timing : Timing that the system uses when reading from and
writing to DRAM. Do not reset from the manufacturer default value.

SRAM Reading Timing : These SRAM timing numbers are the pattern of cycles the
CPU uses to read data from the cache. Do not reset this option from its default.

SRAM Writing Timing : If necessary, you can insert a wait state in the SRAM write
cycle.

Hidden Refresh : When Disabled, DRAM is refreshed by IBM AT methodology, using a
CPU cycles for each refresh. When hidden refresh is Enabled, the DRAM controller
seeks the most opportune moment for a refresh, regardless of CPU cycles, with least
disruption of system activity and least performance penalty. Hidden refresh is faster
and more efficient, and it also allows the CPU to maintain the status of the DRAM even if
the system goes into a power management “suspend” mode.

Memory Holes (15M-16M) : The default setting is “Disable”. Set to “Enable” means
that when the system memory size is equal to or greater than 16M bytes, the physical
memory address from 15M to 16M will be passed to PCI or ISA and there will be 1M
Bytes hole in your system memory. This option is designed for some OS with special
add-on cards which need 15M-16M memory space.

ISA I/O Recovery : The CPU and local bus are much faster than industry standard
architecture (ISA) input / output (I/O) bus. Select Enabled to allow additional time for
I/O devices to respond to the system. Otherwise, data could be lost. If all your I/O
devices are capable of fast I/O, selecting Disabled can speed up processing.

Fast-Back-to-Back : When Enable, consecutive write cycles targeted to the same slave
become fast back-to-back on the PCI bus.

Special Functions Port : Select Touch Screen I/O ports address.

Touch Controller IRQ : Select Touch Screen IRQ.

Slot X Using INT# : Some PCI devices use interrupts to signal that they need to use the
PCI bus. Other devices, notably most graphics adapters, do not need interrupt service
at all. Each PCI slot can activate up to four interrupts, INT#A, INT#B, INT#C and INT#D.
By default, a PCI slot is allowed INT#A. Assigning INT#B has no meaning unless the
device in the slot requires two interrupt services rather than just one. Likewise, using
INT#C can only mean the device requires three interrupts; and using INT#D, four
interrupts. The default, AUTO, allows the PCI controller to automatically allocate the
interrupts.

PCI IRQ Activated by : Leave the IRQ trigger set at Level unless the PCI device
assigned to the interrupt specifies Edge-triggered interrupts.

PCI IDE 2nd Channel : You can use this selection to enable or disable the second IDE
channel.

BIOS SETUP

TF-486 / 38

PCI IDE IRQ Map to : The PCI IDE interface in the chipset has two channels, it requires
two interrupt services. The primary and secondary IDE INT# fields default to values
appropriate for two IDE channels, with the primary PCI IDE channel having a lower
interrupt than the secondary.

CPU to PCI Write Buffer : When Enable, the CPU can write up to four dwords of data to
the PCI write buffer before the CPU must wait for the PCI bus cycles to finish. When
Disabled, the CPU must wait after each write cycle until the PCI bus signals that it is
ready to receive more data.

CPU to PCI Byte Merge : Byte merging permits merging of the data in consecutive
CPU-to-PCI byte / word writes with the same dword address, into the same posted write
buffer location. The merged collection of bytes is then sent over the PCI Bus as a
single dword. Byte merging is performed in the compatible VGA range only (0A0000­0BFFFF)

PCI to DRAM Buffer : The system supports buffered writes from the PCI bus to DRAM
for greater efficiency.

3.11 Supervisor/User Password

The “SUPERVISOR/USER PASSWORD” utility sets the password. The CPU card is
shipped with the password disabled. If you want to change the password, you must first
enter the current password, then at the prompt enter your new password. The
password is case sensitive and you can use up to 8 alphanumeric characters, press
<Enter> after entering the password. At the next prompt, confirm the new password by
typing it and pressing <Enter> again.

To disable the password, press the <Enter> key instead of entering a new password
when the “Enter Password” dialog box appears. A message will appear confirming that
the password is disabled.

If you have set both supervisor and user password, only the supervisor 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 on the S1 (open pad) for 5 seconds,
then removing the shunt.
