Introduction
Thank you for purchasing the NOVA-7895 Socket 370 Celeron®,
Pentium III®(FC-PGA) with two 10/100Mbps Ethernet ports,
VGA, IEEE1394 and Audio Board. It is equipped with a high
performance Intel®Celeron up to 1.4GHz, Pentium III (FC-PGA)
1 GHz (or above) Processor and an advanced high performance
multi-mode I/O, designed for system manufacturers, integrators,
or VARs looking to combine excellent performance, reliability
and quality at a reasonable price.
This board has a built-in IDE Interface CompactFlash™ Disk
(Type II) for embedded applications. The CompactFlash™ Disk
is 100% compatible with all hard drives. Users can use any DOS
command without installing any extra software utility. The Flash
Disk is currently available from 128MB to 1GB.
Two advanced high performance LPC super I/O chips – ITE
(IT8705F) and NS (NS87366) are used in the NOVA-7895 board.
The on-chip UARTs are compatible with NS16C550. The parallel
port and FDD interface are compatible with IBM PC/AT
architecture.
NOVA-7895 uses the advanced SIS SIS630STT Chipset which
is a 100% PCI compatible chipset (PCI 2.1 standard). In addition,
this board provides one 168-pin socket for on-board DRAM.
Each DIMM module is 3.3V SDRAM with max. 512MB.
The VGA chip (On chip SIS300) used on NOVA-7895 supports
dual view functions which can display simultaneously on two
monitors under WINDOWS 9X/ME. In general, this function is
achieved by two VGA chips.

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
Status Page Setup Menu and Option Page Setup
Menu -- Exit current page and return to Main Menu
PgUp key Increase the numeric value or make changes
PgDn key Decrease the numeric value or make changes
+ key Increase the numeric value or make changes
- key Decrease the numeric value or make changes
F1 key General help, only for Status Page Setup Menu and
Option Page Setup Menu
(Shift)F2 key Change color from total 16 colors. F2 to select color
forward, (Shift) F2 to select color backward
F3 key Calendar, only for Status Page Setup Menu
F4 key Reserved
F5 key Restore the previous CMOS value from CMOS, only
for Option Page Setup Menu
F6 key Load the default CMOS value from BIOS default
table, only for Option Page Setup Menu

NOVA-7895 Socket 370 Celeron TM & Pentium III ®
Multimedia & Dual Ethernet ,IEEE1394, Embedded Board 35
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.

36
Note that a brief description of each highlighted selection appears at the
bottom of the screen.
The main menu includes the following main setup categories. It is
important to remember that some systems may not include all entries.
Standard CMOS Features
Use this menu for basic system configuration. See Section 4.6 for details.
Advanced BIOS Features
Use this menu to set the Advanced Features available on your system.
See Section 4.7 for details.
Advanced Chipset Features
Use this menu to change the values in the chipset registers and optimize
system performance. See section 4.8 for details.
Integrated Peripherals

Use this menu to specify your settings for integrated peripherals. See
section 4.9 for details.
Power Management Setup
Use this menu to specify your power management settings. See section
4.10 for details.
PnP / PCI Configuration
This entry appears if your system supports PnP / PCI. See section 4.11
for details.
PC Health Status
Use this menu to monitor your hardware. See section 4.12 for details.
Frequency/Voltage Control
Use this menu to specify frequency/voltage control settings. See section
4.13 for details.
Load Fail-Safe Defaults
Use this menu to load the BIOS default values for minimal/stable
performance for your system to operate. See section 4.14 for details.
Load Optimized Defaults
Use this menu to load the factory BIOS default values for optimal
performance system operations. While Award has designed the custom
BIOS to maximize performance, the factory has the right to change these
defaults to meet their needs. See section 4.14 for details.
Set Password
Use this menu to set User and Supervisor Passwords. See section 4.15
for details.
