2.3 Unpacking Precautions

Some of the components on the NOVA-7895 are very sensitive to
static electric charges and can be damaged by a sudden rush of
power. To protect them from accidental damage, please be sure to
follow these precautions:

 Ground yourself to remove any static charge before touching your

NOVA-7895. You can do it by using a grounded wrist strap at all
times or by frequently touching any conducting materials that are
connected to the ground.

 Handle your NOVA-7895 at the edges. Don’t touch IC chips, leads

or circuitry if not necessary.



Do not plug in any connector or jumper while the power is on.

 Do not put your NOVA-7895 unprotected on a flat surface as it has

sensitive components on both sides.

2.4 Clear CMOS Setup

If you forget the CMOS password, you can clear or reset it by
closing the

JP6

. After JP6 (1-2) is closed, turn on the power for
about 3 seconds then turn it off and re-open the JP6 (1-2). Now,
the password has been cleared from your CMOS.

AWARD BIOS SETUP

4.1 Introduction

This section of the manual discusses Award's Setup program built into the ROM
BIOS. The Setup program allows users to modify the basic system configuration.
This special information is then stored in battery-backed RAM so that it retains
the Setup information when the power is turned off.

4.2 Starting Setup

The Award BIOS is immediately activated when the computer is first powered up.
The BIOS reads the system information contained in the CMOS and begins the
process of checking out the system and configuring it. Once complete, the BIOS
will seek an operating system on one of the disks and then launch and turn
control over to the operating system.
While the BIOS is in control, the Setup program can be activated in one of two
ways:

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

2. by pressing the <Del> key when the following message appears briefly at the
bottom of the screen during the POST (Power On Self Test).

Press DEL to enter SETUP.

NOVA-7895 Socket 370 Celeron

TM

& Pentium III ®

Multimedia & Dual Ethernet ,IEEE1394, Embedded Board

34

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 the
<Ctrl>, <Alt>, and <Delete> keys. If you do not press all three keys at the correct
time and the system does not boot, an error message will be displayed and the
following will appear on your screen:

PRESS F1 TO CONTINUE, DEL TO ENTER SETUP

4.3 Using Setup

In general, by using the arrow keys, items can be highlighted, whereas pressing
<Enter> will select the highlighted option. Use the PageUp and PageDown keys
to change entries, press <F1> for help and <Esc> to quit. The following table
provides more details about how to navigate in the Setup program using the
keyboard.

Up arrow Move to previous item
Down arrow Move to next item
Left arrow Move to the item in the left hand
Right arrow Move to the item in the right hand
Esc key Main Menu -- Quit without saving changes into CMOS

F7 key Load the default
F8 key Reserved
F9 key Reserved
F10 key Save all the CMOS changes, only for Main Menu

4.4 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. To exit the Help Window
press <Esc> or the F1 key again.

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 which resets your system to its defaults.
The best advice is to only alter settings which you thoroughly understand. To this
end, we strongly recommend that you avoid making any changes to the chipset
defaults. These defaults have been carefully chosen by both Award and your
systems manufacturer to provide the absolute maximum performance and
reliability. Even a seemingly small change to the chipset setup has the potential
to cause the override to kick in.

4.5 Main Menu

Once you enter the AwardBIOS™ CMOS Setup Utility, the Main Menu
will appear on the screen. This allows you to select from several setup
functions and two exit choices. Use the arrow keys to select among the
items and press <Enter> to accept and enter the sub-menu.

4.8 Advanced Chipset Features

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 DRAM and the external
cache. 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.

Advanced DRAM Control 1 / 2 Settings

The first chipset settings deal with CPU access to dynamic random
access memory (DRAM). The default timings have been carefully chosen
and should only be altered if data is being lost. Such a scenario might
well occur if your system had mixed speed DRAM chips installed so that
greater delays may be required to preserve the integrity of the data held
in the slower memory chips.

every time you try to enter Setup. This prevents an unauthorized user
from changing any part of your system configuration.
Additionally, when a password is enabled, you can also require the BIOS
to request a password every time your system is rebooted. This prevents
unauthorized use of your computer.
You determine when the password is required within the BIOS Features
Setup Menu and its Security option (see Section 3). If the Security option
is set to password, then the password will be required both at boot and at
entry to Setup. If set to “Setup”, prompting only occurs when trying to

Appendix A. Watch-Dog Timer

The Watchdog Timer is a device to ensure that standalone systems can
always recover from abnormal conditions that cause the system to crash.
These conditions may result from an external EMI or a software bug.
When the system stops working, hardware on the board will perform a
hardware reset (cold boot) to bring the system back to a known state.

Three I/O ports control the operation of Watch-Dog Timer.

443 (hex) Write Set Watchdog Time period
443 (hex) Read Enable the refresh the Watchdog Timer.
043/843 (hex) Read Disable the Watch-Dog Timer.

Prior to enabling the Watch-Dog Timer, the user should set the time-out
period. The resolution of the timer is 1 second and the range of the timer
is from 1 to 255 sec. You need to send the time-out value to the I/O
port – 443H, and then enable it by reading data from the same I/O port –
443H. This will activate the timer that will eventually time out and reset
the CPU board. To ensure that this reset condition does not occur, the
Watch-Dog Timer must be periodically refreshed by reading the same I/O
port 443H. This must be done within the time-out period, please refer to
the example program. Finally, be sure to disable the Watch-Dog timer by
reading the I/O port -- 843H or 043H, otherwise the system could reset
unconditionally.

A tolerance of at least 5% must be maintained to avoid unknown routines
in the operating system (DOS), such as disk I/O that can be very time­consuming. Therefore if the time-out period has been set to 10 seconds,
the I/O port 443H must be read within 7 seconds.

Appendix B. POST Messages

POST Messages

During the Power On Self Test (POST), if the BIOS detects an error requiring you
to fix something, it will either sound a beep code or display a message.
If a message is displayed, it will be accompanied by:
PRESS F1 TO CONTINUE, CTRL-ALT-ESC OR DEL TO ENTER SETUP

POST Beep

Currently there are two kinds of beep codes in BIOS. This 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 code indicates that a DRAM error has
occurred. This beep code consists of a single long beep repeatedly.

Error Messages

One or more of the following messages may be displayed if the BIOS detects an
error during the POST. This list includes messages for both the ISA and the EISA

How to Upgrade a New BIOS

You can install an upgrade BIOS for the CPU Board after
downloading from the manufacturer’s web site ( www.iei.com.tw

).
New BIOS may provide support for new peripherals,
improvements in performance or fixes to addressed known bugs.

BIOS Update Procedure:

1. Make a boot disk. Go to the DOS command prompt in MS-DOS
or Windows 9x and, with an available floppy disk in "A", type
"format A: /s" That will format the floppy and transfer the needed
system files to it.

NOTES:
A. This procedure will erase any prior data on that floppy, so
please proceed accordingly.
B. Typically four files will be transferred, only COMMAND.COM
being visible when running a simple directory listing.
C. Please leave the diskette UN-write protected for the balance of
this procedure.

2. Download the BIOS upgrade file and awdflash.exe utility from
an ICP web site to a temp directory on your hard drive, or directly
to the floppy you made in step 1..

3. Copy ( BIOS file and awdflash.exe) two files to the boot floppy.

4. Reboot the system to the DOS command prompt using the boot
diskette you just made.

5. At the DOS command prompt, type "awdflash filename.xxx",

NOVA-7895 Socket 370 Celeron

TM

& Pentium III ®

Multimedia & Dual Ethernet ,IEEE1394, Embedded Board

78

where filename.xxx is the file name of the BIOS file. Press enter.

6. Your first option, in sequence, will be to save the old BIOS. We
recommend that you do that in case, for whatever reason, you
decide you don't wish to use the new version once it is installed.
NOTES:
A. If you decide to save the old BIOS, PLEASE make sure you do
NOT save it to the same file name as the new BIOS - if you use
the same BIOS name the old file will be written over the new file
with NO warning prompt. A simple file name to save the old BIOS
under is OLDBIOS.BIN.
B. If you do NOT decide to save the old BIOS, PLEASE at least
write down the version number of the old BIOS and store that
information with your important computer documents. Enter N (for
"no") and skip to step 9.

7. To save the old BIOS, hit Y (for "yes")

8. Enter a name for the OLD BIOS file and hit enter.
NOTE:PLEASE be sure you do NOT save the old BIOS file to the
same file name as the new BIOS - if you use the same BIOS name,
the old file will write over the new BIOS file WITHOUT a warning
prompt. A simple file name for saving the old BIOS under is
OLDBIOS.BIN.

9. Your second option, in sequence, will be whether or not you
want to flash your BIOS. Enter Y (for "yes").
NOTE: This is a critical step. Once you press the enter key, do
NOT touch the keyboard, the reset button, or the power switch
while the flashing is in progress. There will be bar progressing
across the screen while the flashing is taking place.

10. When the flashing process is complete, you will be asked to
reset or power off the system. Remove the floppy diskette from the

NOVA-7895 Socket 370 Celeron

TM

& Pentium III ®

Multimedia & Dual Ethernet ,IEEE1394, Embedded Board

79

floppy drive and either hit the reset button or the power button.

11. Reboot the system and note that the BIOS version on the initial
boot-up screen has changed to the new BIOS version. Your BIOS
upgrade is now complete.

Recovering Your Old BIOS:

1. Assuming you have made a back-up of the old BIOS on the
floppy during the upgrade procedure noted above, boot the system
with that diskette in the floppy drive. If you have not backed up to a
floppy during the upgrade procedure noted above, you will need to
repeat steps 1 though 3 (above) for the version of the BIOS you
wish to recover to.

2. Complete steps 4, 5, 6B, 9, 10, and 11 (above) substituting the
name of the BIOS you wish to recover for the upgrade BIOS at
step 5.

Appendix E. Digital Input / Output

NOVA-7895 has a 4-bit IN and 4-bit OUT built-in digital I/O connector. An
external power supply to the connector’s pin-9 and pin-10 is needed to
activate the digital I/O circuit. The external power supply’s DC output
should be connected with NOVA-7895’s power supply at either 5V, 12V
or GND to isolate NOVA-7895 main system and the external I/O device.
Should you not be able to find any external power supply to activate the
digital I/O, the 5V or 12V of the system’s power supply can be used.
Under this condition, the digital I/O is not isolated.

Flat Panel Connection Module

The FP24-02 V1.0 connection module is installed on the NOVA­7895 as standard. The FP24-02 V1.0 converts NOVA-7895’s on
board 50pin LCD interface signal to the 44-pin LCD connectors.
The 44-pin connector will only support a 24-bit flat panel. The major
function of FP24-02 V1.0 is to enhance the drive strength of LCD
signal to provide NOVA-7895 with a better connection.
