Chapter 3 AMIBIOS Setup 43

Power management/APM

Power management lets you set up your computer to save
electricity when it is not actively in use by putting the system into
progressively greater power saving modes. In the power manage­ment scheme there are four system states which proceed in the
following sequence:

Disabled à SMI

There are two selections for Power Management (Mode):

Disabled Turns off PM
SMI Maximized power saving by activating

maximum power saving settings after one
minute of system inactivity.

With the exception of Disabled, SMI selections have "fixed-
mode" settings. Therefore, when PM is set to Disabled, some
items which are predefined will become unmodifiable.

Power down HDD mode

When enabled and after the selected time of system inactivity, the
hard disk drive will be powered down while all other devices will
remain active.

Doze mode timeout

This sets the period of system inactivity after which the system
goes into Doze mode, the most limited power saving state. The
settings range from 10 seconds to 2 hours and can be set manual­ly when power management is in SMI. The default setting is
Disabled. When the system goes into power saving mode, power
management will skip to the next mode in the sequence if this is
disabled.

44 PCM-4335 User Manual

Standby mode timeout

This sets the period of system inactivity after which the system
goes into Standby mode, the intermediate power saving state.
The settings range from 10 seconds to 2 hours and can be set
manually when power management is in SMI. The default setting
is Disabled. When the system goes into power saving mode,
power management will skip to the next mode in the sequence if
this is disabled.

Suspend mode timeout

This sets the period of system inactivity after which the system
goes into Suspend mode, the maximum power saving state. The
settings range from 10 seconds to 2 hours and can be set manual­ly when power management is in SMI. The default setting is
Disabled. When the system goes into power saving mode, power
management will skip to the next mode in the sequence if this is
disabled.

These options specify bus that the named interrupt request lines
(IRQs) are sued on. These options allow you to specify IRQs for
use by legacy ISA adapter cards.

These options determine if AMIBIOS should remove an IRQ from
the pool of available IRQs passed to BIOS configurable devices.
The available IRQ pool is determined by reading the ESCD
NVRAM. If more IRQs must be removed from the pool, the end
user can use these PCI/PnP Setup options to remove the IRQ by
assigning the option to the ISA/EISA setting. Onboard I/O is
configurable by AMIBIOS. The IRQs used by onboard I/O are
configurable by AMIBIOS. The IRQs used by onboard I/O are
configured as PCI/PnP.

The settings are PCI/PnP or ISA/EISA. The default settings are
PCI/PnP.

Setting jumpers

You 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.

1

Open Closed Closed 2-3

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

1 2 3

Open Closed Closed 2-3

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

2

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.

Generally, you simply need a standard cable to make most
connections.

8 PCM-4335 User's Manual

Safety precautions

Warning! Always completely disconnect the power cord

from your chassis whenever you are working on
it. Do not make connections while the power is
on because 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 CPU card. 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.

Floppy drive connector (CN2)

You can attach up to two floppy disks to the PCM-4335's on­board 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.

The PCM-4335 CPU card comes with a 34-pin daisy-chain drive
connector cable. On one end of the cable is a 34-pin flat-cable
connector. There are two sets of floppy disk drive connectors,
one in the middle, and one on the other end. Each set consists of a
34-pin flat-cable connector (usually used for 3.5" drives) and a
printed-circuit board connector (usually used for 5.25" drives).

Connecting the floppy drive

1. Plug the 34-pin flat-cable connector into the floppy disk
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: floppy. The set in the middle connects to the B:
floppy.

IDE hard drive connector (CN4)

You can attach one or two 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. 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 red or blue, and the other wires are
gray.

1. Connect one end of the cable to CN4. 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 1on 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 one as the slave by using jumpers on the
drives. If you install just one drive, set it as the master.

The mainboard provides a keyboard connector which supports
both a keyboard and a PS/2 style mouse. In most cases, especially
in embedded applications, a keyboard is not used. The standard
PC/AT BIOS will report an error or fail during power-on self-test
(POST) after a reset if the keyboard is not present. The mainboard
BIOS Advanced setup menu allows you to select "System Key­board" under the "Present" or "Absent" selection. This allows no­keyboard operation in embedded system applications without the

CHAPTER

Flat Panel/CRT

Controller Display

Drivers and Utilities

This chapter provides information about:

• Driver types and installation

Chapter 4 Driver Installation 57

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/CRT
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/CRT 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 CRT 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.

58 PCM-4335 User Manual

Necessary prerequisites

The instructions in this manual assume that you understand elementa­ry concepts of MS-DOS and the IBM Personal Computer. Before you
attempt to install any driver from the Supporting CD-ROM, you
should:

• Know how to copy files from a CD-ROM to a directory on the hard
disk

• Understand the MS-DOS directory structure

If you are uncertain about any of these concepts, please refer to the
DOS or OS/2 user reference guides for more information before you
proceed with the installation.

Before you begin

Make sure you know the version of the application for which you are
installing drivers. The Supporting CD-ROM contain drivers for several
versions of certain applications. For your driver to operate properly ,
you must install the driver for your version of the application program.
