Chapter 2 Hardware Configuration

2-3 HOW TO SET JUMPERS

You can configure your board by sett i ng jumpers. A jumper co nsists of two or
three metal pins with a plastic base mounted on the card, and a small plastic
“cap”( with a metal contact inside) to connect the pins. So you can set up your
hardware confi guration by “open” or “close” the pins.

The jumper can be combined into sets which called jumper blocks. When the
jumpers are all in the block, you have to put them together to set up the
hardware configuration. The figure below shows how this looks.

JUMPERS AND CAPS

If a jumper has three pins, for examples, labelled PIN1, PIN2, and PIN3. You
can connect PIN1 & PIN2 to create one setting and shorting. You can either
connect PIN2 & PIN3 to create another setting. The same jumper diagrams are
applied a ll through this manual. The figure below shows what the manual
diagrams look and what they represent.

Chapter 5 Award BIOS Setup

5-1. INTRODUCTION

This chapter will show you the function of BIOS in managing the features of
your system. The PC-550 Pentium Embedded Card is equipped with the BIOS
for system chipset from Award Software Inc. This page briefly explains the
function of BIOS in managing the special features of your system. The
following pages describe how to use the BIOS for system chipset Setup menu.

Your application programs (such as wo rd processing, spreadsheets, and games)
rely on an operating system such as DOS or OS/2 to manage such things as
keyboard, monitor, disk drives, and memory.

The operating system relies on BIOS (Basic Input and Output system), a
program stored on a ROM (Read-only Memory) chip, to initialize and
configure your computer's hardware. As the interface between the hardware
and the operating system, the BIOS enables you to make basic changes to your
system's hardware without having to write a new op erating system.

The following diagram illustrates the interlocking relationships between the
system hardware, BIOS, operating system, and application program:

HDD MODE

The Award BIOS supports 3 HDD mode: NORMAL, LBA, & LARGE

NORMAL mode:

Generic access mode in which neither the BIOS nor the IDE controller will
make any transformations during accessing.

The maximum number of cylinders, heads & sectors for NORMAL mode are
1024, 16, &63.

no. Cylinder (1024)
x no. Head ( 16)
x no. Sector ( 63)
x no. Per sector ( 512)

--------------------------------------­ Total: 528 Mega byte

If user set his HDD to NORMAL mode, the maximum accessible HDD size
will be 528 Megabytes even though its physical size may be greater than that.

LBA (logical Block Addressing) mode:

A new HDD accessing method to overcome the 528 Megabyte bottleneck. The
number of cylinders. head & sectors shown in setup may not be the number
physically contained in the HDD.

During HDD accessing, The IDE controller will transform the logical address
described by sector, head & cylinder number into its own physical address
inside the HDD.

The maximum HDD size supported by LBA mode is 8.4 Gigabyte which is
obtained by the following formula:

no. Cylinder (1024)
x no. Head ( 255)
x no. Sector ( 63)
x no. Per sector ( 512)

--------------------------------------­ Total: 8.4 Giga byte

Chapter 5 Award BIOS Setup

LARGE mode

:

Some IDE HDDs contain more than 1024 cylinder without LBA support (in
some cases, user do not want LBA). The BIOS provides another alternative to
support these kinds of HDD.

CYLS HEADS SECTOR MODE

----------------------------------------------------------------­ 1120 16 59 NORMAL
560 32 59 LARGE

BIOS tricks DOS (or other OS) that the number of cylinder 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 INT 13h in order to
access the right HDD address the right HDD address.

Maximum HDD size:

no. Cylinder (1024)
x no. Head ( 32)
x no. Sector ( 63)
x no. Per sector ( 512)

--------------------------------------­ Total: 1 Giga byte

REMARKS

:

To support LBA or LARGE mode of HDDs, there must be some softwares
involved. All these softwares are located in the Award HDD Service Routine
(INT 13h). It may be failed to access a HDD with LBA(LARGE) mode
selected if you are running under a Operating System which replaces the whole
INT 13h.

Appendix C Trouble Shooting

C-1 TROUBLE SHOOTING FOR ERROR MESSAGE

The following information informs you the error messages and the trouble
shooting. Please adjust your systems according to the messages below. And
make sure all the components and connectors are in proper position and firmly
attached. If the errors still encountered, please contact with your distributor for
maintenance.

POST BEEP :

Currently there are two kinds of beep codes in BIOS. The one code indicates
that a video error has occurred and the BIOS cannot initialize the video screen
to display any additional information. This beep code consists of a single long
beep followed by three short beeps. The other one code indicates that your
DRAM error has occurred. This beep code consists of a single long beep
repeatedly.

CMOS BATTERY FAILURE :

When the CMOS battery is out of work or has run out, the user has to replace
the whole unit.

CMOS CHECKSUM ERROR :

This error message informs you that the CMOS is corrupted. When the battery
runs weak, this situation might happen. Please check the battery and change a
new one when necessary.

DISPLAY SWITCH IS SET INCORRECTLY :

Display switch on the motherboard can be set to either monochrome or color.
This indicates the switch is set to a different setting than indicated in Setup.
Determine which setting is correct, and then either turn off the system and
change the jumper, or enter Setup and change the video selection.

DISK BOOT FAILURE:

When you can‘t find the boot device, insert a system disk into Drive A and
press < Enter >. Make sure both the controller and cables are all in proper
positions, also make sure the disk is formatted correct device. Then reboot the
system.

PC-550 USER′S MANUAL

Page: C-2

Appendix C Trouble Shooting

DISKETTE DRIVES OR TYPES MISMATCH ERROR :

When the diskette drive type is different from CMOS, please run setup or
configure the drive again.

ERROR ENCOUNTERED INITIALIZING HARD DRIVE :

When you can‘t initialize the hard drive. Assure the adapter is installed
correctly and all cables are correctly and firmly attached. Also be sure the
correct hard drive type is selected in Setup.

ERROR INITIALIZING HARD DISK CONTROLLER :

When this error occurs. Be sure the cord is exactly installed in the bus. Make
sure the correct hard drive type is selected in Setup. Also check whether all of
the jumpers are set correctly in the hard drive.

FLOPPY DISK CONTROLLER ERROR OR
NO CONTROLLER PRESENT :

When you cannot find or initialize the floppy drive controller, please check the
controller whether in proper Setup. If there are no floppy drive installed,
Ensure the Diskette Drive selection in Setup is set to NONE.

KEYBOARD ERROR OR NO KEYBOARD PRESENT

When this situation happens, please check keyboard attachment and no keys
being pressed during the boot. If you are purposely configuring the system
without a keyboard, set the error halt condition in Setup to HALT ON ALL,
BUT KEYBOARD. This will cause the BIOS to ignore the missing keyboard
and continue the boot.

MEMORY ADDRESS ERROR :

When the memory address indicates error. You can use this location along
with the memory map for your system to find and replace the bad memo ry
chips.

MEMORY SIZE HAS CHANGED :

Memory has been added or removed since the last boot. In EISA mode use
Configuration Utility to re-configure the memory configuration. In ISA mode
enter Setup and enter the new memory size in the memory fields.

MEMORY VERIFYING ERROR :

It indicates an error verifying a value already written to memo ry. Use the
location along with your system's memory map to locate the bad chip.

OFFENDING ADDRESS MISSING :

This message is used in connection with the I/O CHANNEL CHECK and
RAM PARITY ERROR messages when the segment that has caused the
problem cannot be isolated.

REBOOT ERROR :

When this error occurs that requires you to reboot.. Press any key and the
system will reboot.

SYSTEM HALTED :

Indicates the present boot attempt has been aborted and the system must be
rebooted. Press and hold down the CTRL and ALT keys and press DEL.

C-2 TROUBLE SHOOTING FOR POST CODES

When you power on your PC, and the scree n display nothing. You ha ve to
insert the POST Card for test. The address for ISA POST port is 80h. Make
sure the card is in correct slot. The lists below indicate you the error messages.
