2-3. HOW TO SET THE JUMPERS

You can configure your board by setting the jumpers. Jumper is consists of
two or three metal pins with a plastic base mounted on the card, and by using
a small plastic "cap", Also known as the jumper cap (with a metal contact
inside), you are able to connect the pins. So you can set-up your hardware
configuration by "opening" or "closing" pins.

The jumper can be combined into sets that 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 like.

JUMPERS AND CAPS

If a jumper has three pins (for example, 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 all through this manual. The figure below shows what the manual
diagram looks like and what they represent.

This board has watchdog timer function for monitoring whether the system
is still work or not after a period of time. The user can select watchdog
timer to system reset or NMI (Non Maskable interrupt) depending on the
jumper set in “Reset/NMI/Clear Watchdog Selection” found in chapter 2.
This is defined at I/O port 443H. When you want to enable the watchdog
timer, please write I/O port 443H, and then the system will either reset itself
or perform the NMI function. Likewise, when you want to disable the
function, write I/O port 441H, the system will run the command to stop the
Watchdog function.

In Prox-1635 watchdog function, you must write your program so when it
writes I/O port address 443 for enable watchdog and write I/O port address
441 for disable watchdog. The timer's intervals have a tolerance of 25% so
you should program an instruction that will refresh the timer about every
second.

The following program shows you how to program the watch timer in your
program.

Watchdog enable program:

MOV AX, 000FH (choose the values you need; start from 0)

Chapter 4 Award BIOS Setup

4-1. INTRODUCTION

This chapter will show you the function of the BIOS in managing the
features of your system. The Prox-1635 Socket 370 CPU Card is equipped
with the BIOS for system chipset from Award Software Inc. This page
briefly explains the function of the 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 word 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 the 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 operating system.

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

IDE Primary Master / Slave:
IDE Secondary Master / Slave:

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 detect its specifications during POST, every time system
boots.

If you do not want to select drive type AUTO, other methods of selecting
drive type are available:

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

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

3. Use the IDE HDD AUTO DETECTION function in Setup.

Here is a brief explanation of drive specifications:

Type: 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 predefine type are
classified as type USER.

Chapter 4 Award BIOS Setup

• Size: Disk drive capacity (approximate). Note that this size is usually
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 cylinders.

• 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, sectors

supported are 1024, 16 and 63.

 Large: For drives that do not support LBA and have more

than 1024 cylinders.

Chipset Features Setup Screen

This parameter allows you to configure the system based on the specific
features of the installed chipset. The chipset manages bus speed and
access to system memory resources, such as DRAM and the external cache.

It also coordinates communications between 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 the system. The only time you might consider making
any changes would be if you discovered that data was being lost while
using your system.

SHOOTING

This section outlines the error messages that may occur when you
operate the system. It also gives you the suggestions on solving the
problems.

Section includes:

z Trouble Shooting for Error Messages

z Trouble Shooting for POST Code

Page: C-1

Appendix C Trouble Shooting

TROUBLE SHOOTING FOR ERROR MESSAGES

The following information gives you the error messages and the trouble­shooting. 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. 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 two short beeps. The other code indicates that
your DRAM error has occurred. This beep code consists of a single long
beep repeatedly.

CMOS BATTERY HAS FAILED :

This message informs you that the CMOS battery is no longer functional.
The user should replace it.

CMOS CHECKSUM ERROR :

This message informs you that the CMOS is incorrect. This error may
have caused by a weak battery. Check the battery and replace if necessary.

DISK BOOT FAILURE, INSERT SYSTEM DISK AND PRESS ENTER :

No boot device was found. This could mean that either a boot drive was
not detected or the drive does not contain proper system boot files. Insert a
system disk into Drive A: and press < Enter >. If you assumed the system
would boot from the hard drive, make sure the controller is inserted
correctly and all cables are properly attached. Also make sure the disk is
formatted as a boot device. Then reboot the system.

DISKETTE DRIVES OR TYPES MISMATCH ERROR - RUN SETUP :

Type of diskette drive installed in the system is different from the CMOS
definition. Run Setup to reconfigure the drive type correctly.

Page: C-2

Prox-1635 USER′S MANUAL

Appendix C Trouble Shooting

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.

DISPLAY TYPE HAS CHANGED SINCE LAST BOOT :

Since last powering off the system, the display adapter has been changed.
You must configure the system for the new display type.

EISA CONFIGURATION CHECKSUM ERROR
PLEASE RUN EISA CONFIGURATION UTILITY :

The EISA non-violatile RAM checksum is incorrect or cannot correctly
read the EISA slot. This can indicate either the EISA non-volatile
memory has become corrupt or the slot has been configured incorrectly.
Also be sure the card is installed firmly in the slot.

EISA CONFIGURATION IS NOT COMPLETE
PLEASE RUN EISA CONFIGURATION UTILITY :

The slot configure information stored in the EISA non-volatile memory is
incomplete.
Note: When either of these errors appear, the system will boot in ISA mode,
which allows you to run the EISA Configuration Utility.

ERROR ENCOUNTERED INITIALIZING HARD DRIVE :

Hard drive cannot be initialized. Be sure 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 :

Cannot initialize controller. Make sure the cord is correctly and firmly
installed in the bus. Be sure the correct hard drive is selected in Setup. Also
check to see if any jumper needs to be set correctly on the hard drive.

Prox-1635 USER′S MANUAL

Page: C-3

Appendix C Trouble Shooting

FLOPPY DISK CNTRLR ERROR OR NO CNTRLR PRESENT :

Cannot find or initialize the floppy drive controller. Make sure the
controller is installed correctly and firmly. If there are no floppy drives
installed, be sure the Diskette Drive selection in Setup is set to NONE.

INVALID EISA CONFIGURATION
PLEASE RUN EISA CONFIGURATION UTILITY

:

The non-volatile memory containing EISA configuration information was
programmed incorrectly or has become corrupt. Re-run EISA configuration
utility to correctly program the memory.
Note: When this error appears, the system will boot in ISA mode, which
allows you to run the EISA Configuration Utility.

KEYBOARD ERROR OR NO KEYBOARD PRESENT

:

Cannot initialize the keyboard. Make sure that the keyboard is properly
attached 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 AT ... :

Indicates a memory address error at a specific location. You can use this
location along with the memory map for your system to find and replace the
bad memory chips.

MEMORY PARITY ERROR AT ... :

Indicates a memory parity error at a specific location. You can use this
location along with the memory map for your system to find and replace the
bad memory chips.

MEMORY SIZE HAS CHANGED SINCE LAST BOOT :

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

Page: C-4

Prox-1635 USER′S MANUAL

Appendix C Trouble Shooting

MEMORY VERIFY ERROR AT ... :

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

OFFENDING ADDRESS NOT FOUND :

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

OFFENDING SEGMENT :

This message is used in conjunction with the I/O CHANNEL CHECK and
RAM PARITY ERROR messages when the segment that has caused the
problem has been isolated.

PRESS A KEY TO REBOOT :

This will be displayed at the bottom screen when an error occurs that
requires you to reboot. Press any key and the system will reboot.

PRESS F1 TO DISABLE NMI, F2 TO REBOOT :

When BIOS detects a Non-maskable Interrupt condition during boot, this
will allow you to disable the NMI and continue to boot, or you can reboot
the system with the NMI enabled.

RAM PARITY ERROR – CHECKING FOR SEGMENT :

Indicates a parity error in Random Access Memory.

Should be Empty But EISA Board Found
PLEASE RUN EISA CONFIGURATION UTILITY :

A valid board ID was found in a slot that was configured as having no
board ID.
Note: When this error appears, the system will boot in ISA mode, which
allows you to run the EISA Configuration Utility.

Should Have EISA Board But Not Found
PLEASE RUN EISA CONFIGURATION UTILITY :

The board installed is not responding to the ID request, or no board ID has
been found in the indicated slot.
Note: When this error appears, the system will boot in ISA mode, which
allows you to run the EISA Configuration Utility.

Prox-1635 USER′S MANUAL

Page: C-5

Appendix C Trouble Shooting

Slot Not Empty :

Indicates that a slot designated as empty by the EISA Configuration Utility
actually contains a board.

SYSTEM HALTED, (CTRL-ALT-DEL) TO REBOOT :

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.

Wrong Board in Slot
PLEASE RUN EISA CONFIGURATION UTILITY :

The board ID does not match the ID stored in the EISA non-volatile
memory.
