Setting jumpers

You can configure your card to match the needs of your application
by setting jumpers. A jumper is the simplest kind of electric switch.
It consists of two metal pins and a small metal clip (often protected
by a plastic cover) that slides over the pins to connect them. To
“close” a jumper you connect the pins with the clip. To “open” a
jumper you remove the clip. Sometimes a jumper will have three
pins, labeled 1, 2, and 3. In this case you would connect either pins
1 and 2 or 2 and 3.

The jumper settings are schematically depicted in this manual as
follows:

A pair of needle-nose pliers may be helpful when working with
jumpers.

If you have any doubts about the best hardware configuration for
your application, contact your local distributor or sales representa­tive before you make any changes.

CPU installing and upgrading

Y ou can upgrade to a more powerful Celeron CPU at any time.
Simply remove the old CPU, install the new one, and set the
jumpers for the new CPU speed.

Warning! Always disconnect the power cord from your

chassis when you are working on it. Do not
make connections while the power is on as
sensitive electronic components can be dam­aged by the sudden rush of power. Only experi­enced electronics personnel should open the
system chassis.

Caution! Always ground yourself to remove any static

charge before touching the system board.
Modern electronic devices are very sensitive to
static electric charges. Use a grounding wrist
strap at all times. Place all electronic components
on a static-dissipative surface or in a static­shielded bag when they are not in the chassis.

Instala a CPU in the ZIF socket

SBC-675 Series provides a Zero Insertion Force (ZIP) socket for
easy CPU installation.

1. Make sure the ZIF socket lever is in the upright position. To

raise the lever, pull it out to the side a little and raise it as far as
it will go.

2. Place the CPU in the empty socket. Follow the instructions that

came wth the CPU. If you have no instructions, do the follow­ing: Carefully align the CPU so it is parallel to the socket and
the notch on the corner of the CPU corresponds with the notch
on the inside of the socket. Gently slide the CPU in. It should
insert easily . If it doesn't, pull the lever up a little more.

16 SBC-675 User Manual

3 . Press the lever down. The plate will slide forward. Y ou will feel

some resistance as the pressure starts to secure the CPU in the
socket. This normal and won't damage the CPU.

When the CPU is installed, the lever should snap into place at the
side of the socket.

Note: To remove a CPU, pull the lever out to the side a

little and raise it as far as it will go. Lift out the
CPU chip.

When you install a new CPU, be sure to adjust the board settings,
such as CPU type and CPU clock. Improper settings may damage

the CPU.

Chapter 2 Installation 17

Installing DRAM (DIMMs)

System Memory

The left edge of the SBC-675 contains three sockets for 168-pin
dual inline memory module (DIMM). The socket uses 3.3 V
unbuffered synchronous DRAM (SDRAM). DIMM is available in
capacities of 16, 32, 64, or 128 MB. The socket can be filled in the
DIMM of any size, giving your SBC-675 single board computer
between 16 and 128 MB of memory .

Supplementary information about DIMM

Y our SBC-675 can accept both regular and PC-100 SDRAM DIMM
Module(with or without parity). However, if the Celeron with
100MHz FSB CPU is used. The SBC-675 can only accept PC-100
SDRAM DIMM Module.

Single-sided modules are typically 16 or 64 MB; double-sided
modules are usually 32 or 128 MB.

Memory Installation Procedures

T o install DIMM, first make sure the two handles of the DIMM
socket are in the "open" position. i.e. The handles remain outward.
Slowly slide the DIMM module along the plastic guides on both
ends of the socket. Then press the DIMM module right down into
the socket, until you hear a click. This is when the two handles
have automatically locked the memory module into the correct
position of the DIMM socket. (See Figure below) T o take away the
memory module, just push both handles outward, and the memory
module will be ejected by the mechanism in the socket.

18 SBC-675 User Manual

Cache memory

Since the second level cache has been embedded into the Celeron
CPU, you do not have to take care of either SRAM chips or SRAM
modules. The built-in second level cache in the Celeron yields
much higher performance than the external cache memories. The
cache size in the Celeron CPU is either 128 KB.

You can attach up to four Enhanced Integrated Device Electronics
hard disk drives to the mainboard's internal controller. The
mainboard's IDE controller uses a PCI local-bus interface. This
advanced interface supports faster data transfer and allows the IDE
hard drive to exceed 528 MB.

Connecting the hard drive

Connecting drives is done in a daisy-chain fashion and requires
one of two cables, depending on the drive size.

Wire number 1 on the cable is normally red or blue, and the other
wires are usually gray .

1. Connect one end of the cable to CN2 or CN8. Make sure that
the red (or blue) wire corresponds to pin 1 on the connector,
which is labeled on the board (on the right side).

2. Plug the other end of the cable to the Enhanced IDE hard drive,
with pin 1 on the cable corresponding to pin 1 on the hard
drives. (see your hard drive's documentation for the location of
the connector).

Connect a second drive as described above.
Unlike floppy drives, IDE hard drives can connect to either end

of the cable. If you install two drives, you will need to set one
as the master and the other one as the slave by using jumpers
on the drives. If you install just one drive, set it as the master .

Floppy drive connector (CN3)

You can attach up to two floppy drives to the mainboard control­ler. You can use any combination of 5¼" (360 KB and 1.2 MB)
and/or 3½" (720 KB, 1.44 MB, and 2.88 MB) drives.

A 34-pin daisy-chain drive connector cable is required for a dual­drive system. On one end of the cable is a 34-pin flat-cable
connector. On the other end are two sets of floppy disk drive
connectors. Each set consists of a 34-pin flat-cable connector
(usually used for 3½" drives) and a printed-circuit board connec­tor (usually used for 5¼" drives).

Wire number 1 on the cable is normally red or blue, and the other
wires are usually gray.

Connecting the floppy drive

1 . Plug the 34-pin flat-cable connector into CN3. Make sure that

the red or blue wire corresponds to pin 1 on the connector.

2. Attach the appropriate connector on the other end of the cable
to the floppy drive(s). You can use only one connector in the
set. The set on the end (after the twist in the cable) connects to
the A: drive. The set in the middle connects to the B: drive.

3. If you are connecting a 5¼" floppy drive, line up the slot in the
printed circuit board with the blocked-off part of the cable
connector.

If you are connecting a 3½" floppy drive, you may have trouble
determining which pin is pin number 1. Look for a number
printed on the circuit board indicating pin number 1. Also,

the connector on the floppy drive connector may have a slot.

When the slot is up, pin number 1 should be on the right.

Check the documentation that came with the drive for more

information.

If you desire, connect the B: drive to the connectors in the
middle of the cable as described above.

CHAPTER

42 SBC-675 User Manual

Starting setup

The A ward BIOS is immediately activated when you first turn on
the computer. The BIOS reads system configuration information in
CMOS RAM and begins the process of checking out the system
and configuring it through the power-on self test (POST).

When these preliminaries are finished, the BIOS seeks an operating
system on one of the data storage devices (hard drive, floppy
drive, etc.). The BIOS launches the operating system and hands
control of system operations to it.

During POST , you can start the Setup program in one of two ways:

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

2.By pressing Del or pressing Ctrl-Alt-Esc when the following
message appears briefly at the bottom of the screen during POST:

TO ENTER SETUP BEFORE BOOT PRESS DEL KEY

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 Ctr-Alt-Del. If you do not
press the keys at the correct time and the system does not boot, an
error message appears and you are again asked to

key again.

In Case of Problems

If, after making and saving system changes with Setup, you
discover that your computer no longer is able to boot, the Award-
BIOS supports an override to the CMOS settings that resets your
system to its default configuration.

You can invoke this override by immediately pressing Insert; when
you restart your computer. You can restart by either using the ON/
OFF switch, the RESET button or by pressing Ctrl-Alt-Delete.

The best advice is to alter only settings that you thoroughly
understand. In particular, do not change settings in the Chipset
screen without a good reason. The Chipset defaults have been
carefully chosen by Award Software or your system manufacturer
for the best performance and reliability . Even a seemingly small
change to the Chipset setup may causing the system to become
unstable.

HARD DISKS

The BIOS supports up to four IDE drives. This section does not
show information about other IDE devices, such as a CD-ROM
drive, or about other hard drive types, such as SCSI drives.

NOTE: We recommend that you select type AUTO for all drives.

The BIOS can automatically detect the specifications and optimal
operating mode of almost all IDE hard drives. When you select
type AUTO for a hard drive, the BIOS detects its specifications
during POST, every time the system boots.

If you do not want to select drive type AUTO, other methods of

Chapter 3 Award BIOS Setup 49

selecting the drive type are available:

1.Match the specifications of your installed IDE hard drive(s) with
the preprogrammed values for drive types 1 through 45.

2.Select USER and enter values into each drive parameter field.

3.Use the IDE HDD AUTO DECTECTION function in Setup.
Here is a brief explanation of drive specifications:

•T ype: The BIOS contains a table of pre-defined drive types. Each

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

•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.

• Cyls: Number of cylinders

• Head: Number of heads

• Precomp: W rite precompensation cylinder

• Landz: Landing zone

• Sector: Number of sectors

• 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.

50 SBC-675 User Manual

- LBA (Logical Block Addressing): During drive accesses, the
IDE controller transforms the data address described by

sector, head, and cylinder number into a physical block
address, significantly improving data transfer rates. For
drives with greater than 1024 cylinders.

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 64 MB, 128 MB, or more.

•Base Memory

T ypically 640 KB. Also called conventional memory . The DOS
operating system and conventional applications use this area.

Chapter 3 Award BIOS Setup 53

•Extended Memory

Above the 1-MB boundary . Early IBM personal computers could
not use memory above 1 MB, but current PCs and their software
can use extended memory .

•Other Memory

Between 640 KB and 1 MB; often 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 .

Virus Warning

When enabled, you receive a warning message if a program
(specifically , a virus) attempts to write to the boot sector or the
partition table of the hard disk drive. You should then run an anti­virus program. Keep in mind that this feature protects only the boot
sector, not the entire hard drive.

NOTE: 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 first disable the virus
warning.

CPU Internal Cache/External Cache

Cache memory is additional memory that is much faster than
conventional DRAM (system memory). CPUs from 486-type and up
contain internal cache memory , and most, but not all, modern PCs
have additional (external) cache memory . When the CPU requests
data, the system transfers the requested data from the main DRAM
into cache memory , for even faster access by the CPU.

The External Cache field may not appear if your system does not
have external cache memory .

CPU L2 Cache ECC Checking

When you select Enabled, memory checking is enable when the
external cache contains ECC SRAMs.

Quick Power On Self T est

Select Enabled to reduce the amount of time required to run the
power-on-self-test (POST). A quick POST skips certain steps. W e
recommend that you normally disable quick POST . Better to find a
problem during POST than lose data during your work.

56 SBC-675 User Manual

Boot Sequence

The original IBM PCs loaded the DOS operating system from drive
A (floppy disk), so IBM PC-compatible systems are designed to
search for an operating system first on drive A, and then on drive C
(hard disk). However, the BIOS now of fers many boot sequence
options.

Swap Floppy Drive

This field is effective only in systems with two floppy drives.
Selecting enabled assigns physical drive B to logical drive A, and
physical drive A to logical drive B.

Boot Up Floppy Seek

When Enabled, the BIOS tests (seeks) floppy drives to determine
whether they have 40 or 80 tracks. Only 360-KB floppy drives have
40 tracks; drives with 720 KB, 1.2 MB, and 1.44 MB capacity all
have 80 tracks. Because very few modern PCs have 40-track floppy
drives, we recommend that you set this field to Disabled to save
time.

Boot Up NumLock Status

T oggle between On or Of f to control the state of the NumLock key
when the system boots. When toggled On, the numeric keypad
generates numbers instead of controlling cursor operations.

Gate A20 Option

Gate A20 refers to the way the system addresses memory above 1
MB (extended memory). When set to Fast, the system chipset
controls Gate A20. When set to Normal, a pin in the keyboard
controller controls Gate A20. Setting Gate A20 to Fast improves
system speed, particularly with OS/2 and Windows.

Security Option

If you have set a password, select whether the password is
required every time the System boots, or only when you enter
Setup.

Chapter 3 Award BIOS Setup 57

Shadow

Software that resides in a read-only memory (ROM) chip on a
device is called firmware. The A wardBIOS permits shadowing of
firmware such as the system BIOS, video BIOS, and similar operat­ing instructions that come with some expansion peripherals, such
as, for example, a SCSI adaptor.

Shadowing copies firmware from ROM into system RAM, where
the CPU can read it through the 16-bit or 32-bit DRAM bus.
Firmware not shadowed must be read by the system through the 8­bit X-bus. Shadowing improves the performance of the system
BIOS and similar ROM firmware for expansion peripherals, but it
also reduces the amount of high memory (640 KB to 1 MB) avail­able for loading device drivers, etc.

Enable shadowing into each section of memory separately . Many
system designers hardwire shadowing of the system BIOS and
eliminate a System BIOS Shadow option.

V ideo BIOS shadows into memory area C0000-C7FFF . The remain­ing areas shown on the BIOS Features Setup screen may be
occupied by other expansion card firmware. If an expansion
peripheral in your system contains ROM-based firmware, you need
to know the address range the ROM occupies to shadow it into the
correct area of RAM.

CHIPSET features setup

By choosing the CHIPSET FEA TURES SETUP option from the
INITIAL SETUP SCREEN menu, the screen below is displayed.

Chapter 3 Award BIOS Setup 59

The displayed configuration is based on the manufacturer's SETUP
DEF AUL TS settings.

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 SDRAM.
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. The only time you might consider making any changes
would be if you discovered that data was being lost while using
your system.

Because of the complexity and technical nature of some of the
options, not all of the options are described here.

SDRAM RAS-to-CAS Delay

This field lets you control the number of DCLKs between a Row
Activate command and a read or write command.

SDRAM RAS Precharge Time

The precharge time is the number of cycles it takes for the RAS to
accumulate its charge before DRAM refresh. If insufficient time is
allowed, refresh may be incomplete and the DRAM may fail to
retain data. This field applies only if synchronous DRAM is
installed in the system.

SDRAM CAS Latency Time

When synchronous DRAM is installed, you can control the
number of CLKs between when the SDRAMs sample a read
command and when the contoller samples read data from the
SDRAMs. Do not reset this field from the default value specified
by the system designer.

60 SBC-675 User Manual

SDRAM Precharge Control

When Enabled, all CPU cycles to SDRAM result in an All Banks
Precharge Command on the SDRAM interface.

DRAM Data Integrity Mode

Select Non-ECC or ECC (error-correcting code), according to the
type of installed DRAM.

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.

Video BIOS Cacheable

Selecting Enabled allows caching of the video BIOS ROM at
C0000h to C7FFFh, resulting in better video performance. However,
if any program writes to this memory area, a system error may
result.

Video RAM Cacheable

Selecting Enabled allows caching of the video memory (RAM) at
A0000h to AFFFFh, resulting in better video performance. Howev­er, if any program writes to this memory area, a memory access error
may result.

8/16 Bit I/O Recovery Time

The I/O recovery mechanism adds bus clock cycles between PCI­originated I/O cycles to the ISA bus. This delay takes place
because the PCI bus is so much faster than the ISA bus.

These two fields let you add recovery time (in bus clock cycles) for
16-bit and 8-bit I/O.

Chapter 3 Award BIOS Setup 61

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.

Passive Release

When Enabled, CPU to PCI bus accesses are allowed during
passive release. Otherwise, the arbiter only accepts another PCI
master access to local DRAM.

Delayed 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.

Auto Detect DIMM/PCI Clk

When the Auto Detect DIMM/PCI clk enable, the Utility will
automatically detect the DIMM/PCI clock in your system.

Spread Spectrum

When the system clock generator pulses, the extreme values of the
pulse generate excess EMI. Enabling pulse spectrum spread
modulation changes the extreme values from spikes to flat curves,
thus reducing EMI. This benefit may in some cases be outweighed
by problems with timing-critical devices, such as a clock-sensitive
SCSI device

IN0-IN6(V)

These fields display the current voltage of up to seven voltage
input lines, if your computer contains a monitoring system.

MODEM Use IRQ

Name the interrupt request (IRQ) line assigned to the modem (if
any) on your system. Activity of the selected IRQ always awakens
the system.

Doze Mode

After the selected period of system inactivity , the CPU clock
throttles to a small percentage of its duty cycle — between 10
percent and 25 percent for most chipsets. All other devices still
operate at full speed.

Chapter 3 Award BIOS Setup 65

Standby Mode

After the selected period of system inactivity , the CPU clock stops,
the hard drive enters an idle state, and the L2 cache enters a power­save mode. All other devices still operate at full speed.

Suspend Mode

After the selected period of system inactivity, the chipset enters a
hardware suspend mode, stopping the CPU clock and possibly
causing other system devices to enter power management modes.

HDD Power Down

After the selected period of drive inactivity , any system IDE
devices compatible with the AT A-2 specification or later power
manage themselves, putting themselves into an idle state after the
specified timeout and then waking themselves up when accessed.

Throttle Duty Cycle

When the system enters Doze mode, the CPU clock runs only part
of the time. You may select the percent of time that the clock runs.

VGA Active Monitor

When Enabled, any video activity restarts the global timer for
Standby mode.

Software drivers

This chapter describes the operation and installation of the display
drivers supplied on the Supporting CD-ROM that are shipped with
your product.

The onboard VGA adapter is based on the CHIPS VGA Flat Panel/CR T
controller and is fully IBM VGA compatible. This controller offers a
large set of extended functions and higher resolutions. If you intend to
use your VGA adapter in standard VGA modes only , you do not need
to install any of these drivers. Since your VGA adapter is fully compat­ible, it does not require any special drivers to operate in standard
modes.

The purpose of the enclosed software drivers is to take advantage of
the extended features of the CHIPS VGA Flat Panel/CR T controller .

Hardware configuration

Some of the high-resolution drivers provided in this package will work
only in certain system configurations. If a driver does not display
correctly , try the following:

1 . Change the display controller to CRT-only mode, rather than flat

panel or simultaneous display mode. Some high-resolution drivers
will display correctly only in CR T mode.

2. If a high-resolution mode is not supported on your system, try
using a lower-resolution mode. For example, 1024 x 768 mode will
not work on some systems, but 800 x 600 mode is supported on
most.
