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. T o “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.

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.

14 PCM-4897 User Manual

CPU installing and upgrading

Y ou can upgrade to a more powerful Cyrix GXm 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 PC chassis.

Caution! Always ground yourself to remove any static

charge before touching the PC 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 static-shielded
bag when they are not in the chassis.

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

the CPU.

Chapter 2 Installation 15

Installing DRAM (DIMMs)

System Memory

The PCM-4897 contains a socket 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 PCM-4897 single board computer between 16 and 128 MB of
memory.

Supplementary information about DIMM

Y our PCM-4897 can accept both regular and PC-100 SDRAM
DIMM Module(with or without parity).

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.

Chapter 2 Installation 39

Connecting the hard drive

Connecting drives is done in a daisy-chain fashion and requires
one of two cables, depending on the drive size. 1.8" and 2.5"
drives need a 1 x 44-pin to 2 x 44-pin flat-cable connector. 3.5"
drives use a 1 x 44-pin to 2 x 40-pin connect.

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 CN1. 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.

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.

CHAPTER

Award BIOS Setup

This chapter describes how to configure
the BIOS for the PCM-4897.

Chapter 3 Award BIOS Setup 59

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

PRESS F1 TO CONTINUE, DEL TO ENTER SETUP

Getting help

Press F1 to pop up a small help window that describes the appro­priate keys to use and the possible selections for the highlighted
item. T o exit the Help Window press Esc or the F1 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.

Y ou 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 A ward 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: W e r ecommend that you select type AUT O 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.

66 PCM-4897 User Manual

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

Chapter 3 Award BIOS Setup 67

- 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.

Halt On

During the power-on-self-test (POST), the computer stops if the
BIOS detects a hardware error. You can tell the BIOS to ignore
certain errors during POST and continue the boot-up process.
These are the selections:

• No errors: POST does not stop for any errors.

• All errors If: the BIOS detects any non-fatal error, POST stops
and prompts you to take corrective action.

• All, But Keyboard: POST does not stop for a keyboard error , but

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

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

Chapter 3 Award BIOS Setup 69

•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.

Cache memory is additional memory that is much faster than
conventional DRAM (system memory). CPUs from 486-type on 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 .

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. W e
recommend that you normally disable quick POST . Better to find a
problem during POST than lose data during your work.

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 offers 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 Off 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.

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.

Video 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 75

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 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.

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.

Power Management

This option allows you to select the type (or degree) of power
saving for Doze, Standby, and Suspend modes.

This table describes each power management mode:

Max Saving Maximum power savings. Only Available for

SL CPUs. Inactivity period is 1 minute in
each mode.

User Define Set each mode individually. Select time-out

periods in the section for each mode,
below.

Min Saving Minimum power savings. Inactivity period is

1 hour in each mode (except the hard
drive).

78 PCM-4897 User Manual

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.

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 ATA-2 specification or later power
manage themselves, putting themselves into an idle state after the
specified timeout and then waking themselves up when accessed.

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.

Throttle Duty Cycle

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

Soft-Off by PWR-BTTN

When you select Instant Off or Delay 4 Sec., turning the system off
with the on/off button places the system in a very low-power­usage state, either immediately or after 4 seconds, with only
enough circuitry receiving power to detect power button activity or
Resume by Ring activity .

defaults

LOAD BIOS DEF AUL TS loads the default system values directly
from ROM. The BIOS DEF AUL TS provides the most stable
settings, though they do not provide optimal performance. LOAD
SETUP DEF AUL TS, on the other hand, provides for maximum
system performance. If the stored record created by the setup
utility becomes corrupted (and therefore unusable), BIOS defaults
will load automatically when you turn the PCM-4897 on.

IDE HDD Block Mode

Select Enabled only if your hard drives support block mode.

IDE PIO Modes (Primary Master/Slave)

The four IDE PIO (Programmed Input/Output) fields let you set a
PIO mode (0-4) for each of up to four IDE devices that the internal
PCI IDE interface supports. Modes 0 through 4 provide succes­sively increased performance. In Auto mode, the system automati­cally determines the best mode for each device.

IDE Primary Master/Slave UDMA

UDMA (Ultra DMA) is a DMA data transfer protocol that utilizes
ATA commands and the ATA bus to allow DMA commands to
transfer data at a maximum burst rate of 33 MB/s. When you select
Auto in the four IDE UDMA fields (for each of up to four IDE
devices that the internal PCI IDE interface supports), the system
automatically determines the optimal data transfer rate for each IDE
device.
