SECTION 3
SETTING JUMPERS

This Section describes how to configure hardware options by setting jumper switches on
the VIPer board.

3.01 TERMINOLOGY

Jumper switches are small pins that you can set by using jumper caps. Two pins can be
joined by a jumper cap, thereby closing or shorting a circuit. So you short (or close) a
jumper by placing a plastic jumper cap over two pins of the jumper switch, and you open
a jumper switch by removing a jumper cap.

3.02 JUMPER LOCATIONS ON THE BOARD

Diagram 3-1 on the next page shows 13 jumpers. These appear as rectangular boxes
containing small circles which represent the pins. The jumpers are labeled on the board as
well. When there are more than two pins in a jumper, then some of the pins are also
numbered on the diagram and on the board, so that it will be possible to locate each pin
and its number.

INSTALLING & WORKING WITH SYSTEM COMPONENTS

4.01 MICROPROCESSOR & FAN

4.01.1 MICROPROCESSOR

The VIPer808 supports the following microprocessors (maximum internal CPU clock
speed and CPU voltage are indicated):

• AMD 486DX2SV running at 66 MHz (3.3V);

• AMD 486DX4SV running at 100 MHz (3.3V);

• AMD 5x86 running at 133 MHz (3.3V) .

This processor is also referred to a 486DX5;

• Intel 486DX running at 33 MHz (5V);

• Intel 486DX2 running at 66 MHz (5V);

• Intel 486DX4 running at 100 MHz (3.3V);

• SGS 486DX2V running at 66 MHz (3.3V);

• SGS 486DX4V running at 100 MHz (3.3V).

The Math Co-processor is internal to the CPU (Central Processing Unit).

The above processors also have Internal Cache Memory available.
The following jumpers are related to the CPU:

• W1: Selects the voltage for powering CPU:

- Shorted: 5V,

- Or open: 3.3V.

WARNING: Incorrect CPU voltage can damage your CPU!

• W18: Selects the desired external CPU bus speed:

- W18 pins 3 and 4 shorted: 25MHz,

- Or W18 pins 1 and 2 shorted: 33MHz.

• W15A, W15B and W15C: These jumpers are used in conjunction with W15 to select

CPU Type. See Jumper Settings tables in Section 3 for supported types and their
settings.

Installing & Working With System Components 4-1

• W15: Selects the desired multiplier to set the internal CPU clock speed (2, 3 or 4

times the external bus speed):

- Shorted: 2X (or 4X for AMD 5x86-133 only),

- Or open: 3X.

For DX microprocessors, external bus speed is set to the maximum CPU internal clock
speed or less.

For DX2 microprocessors, external bus speed is set to half the maximum CPU internal
clock speed or less.

For DX4 microprocessors, external bus speed is set to one third the maximum CPU
internal clock speed or less.

For 5x86 microprocessors, external bus speed is set to one fourth the maximum CPU
internal clock speed or less.

Jumper locations and settings appear in Section 3 of this manual.

4.01.2 CPU FAN

You must use a 5V CPU fan on the VIPer808. Pin 1 of the fan connector at J11 is supplied
with 5V (not 12V). A 5V CPU fan assembly (including cables) is available from
TEKNOR.

IMPORTANT: Use a 5V CPU fan on the VIPer808.

Installing & Working With System Components 4-2

4.02 CONFIGURING CACHE

The microprocessors have Internal Cache Memory available for faster execution of
applications.

Cache copies the most recently accessed data and places it in its fast Internal Cache
Memory. The CPU can then access this data at a very high speed. Since most program
executions are sequential and repetitive, the likelihood is great that the CPU will find data
already stored in Cache.

When the CPU retrieves data from Cache, a Cache hit occurs. On the other hand, when
the CPU must access data from System Memory, a Cache miss occurs .

Internal Cache Memory is enabled or disabled in the Advanced Setup screen of the
AMIBIOS Setup program. To run the AMIBIOS Setup program, boot-up your computer
and hit the DELETE key before or when the message - "Hit <DEL> if you want to run
SETUP" - appears near the top of the screen. Set the Internal Cache option in the
Advanced Setup screen to Enabled or Disabled.

Internal Cache Memory is configured as Write Through or Write Back with VIPer808
jumpers. The jumper settings for various CPUs appear on pages 3-7 to 3-10.

The onboard Ethernet controller and port has these features:

ù Supports IEEE 802.3 / ANSI 8802-3 and Ethernet standards.
ù Individual 136-byte transmit and 128-byte receive FIFOs optimize system overhead,

providing sufficient latency during packet transmission and reception, and minimizing
intervention during normal network error recovery.

ù Supports Microsoft’s Plug and Play System configuration for jumperless designs.

Information stored in the serial EEPROM is used to identify the card and to describe
the system resources required by the Plug and Play card, such as I/O space, Memory
space, IRQs and DMA channels. This information is stored in a standardized read only
format.

Installing Peripherals (Parallel/Serial/ Ethernet) 5-10

5.03.2 SETTING UP ETHERNET

Cabling

The VIPer808 is configured with either the Ethernet 10 Base-T or 10 Base-2 interface.
The 10 Base-T interface uses UTP (Unshielded Twisted Pair) cables, category 5,4 or 3 (5
is better). The 10 Base-2 interface uses Thin Ethernet coaxial cables (RG-58). The
impedance is 50 ohms.

Configuration

The Ethernet controller on the VIPer808 is Plug and Play, therefore no manual
configuration is normally required. A diskette entitled “Network Drivers for AM79C961”
is included with the Ethernet option. This diskette contains several operating system
network drivers. You must refer to the READ_NET.TXT (ASCII) or READ_NET.DOC
(WORD 6.0) file, also on the diskette, for instructions on installing the drivers.

Once the proper Ethernet driver is installed, the onboard Plug and Play BIOS and the
driver automatically allocates resources - I/O addresses, IRQ and DMA channels - to the
Ethernet device.

In some cases, it might be absolutely necessary to manually configure the Ethernet
Controller. This is the case when several ISA cards (non Plug and Play) use resources that
might be allocated to the Ethernet controller. A special utility called the PCNETCFG.EXE
was designed for such situations; it will allow you to manually configure the Ethernet
controller.

For the PCNETCFG.EXE utility, other operating system drivers and installation
instructions, or for more information, contact TEKNOR’s Technical Support department.

INSTALLING VIDEO

The VIPer808 video system includes a local bus CRT video controller and 1MB of video
memory (optional 512KB).

7.01 CRT SVGA CONTROLLER

The VIPer808's CRT Super VGA controller is a single-chip video controller from Cirrus
Logic (CL-GD5429). It is fully compatible with the IBM VGA standard at the

hardware and BIOS level.

7.01.1 CRT SUPPORT

The video controller supports both monochrome and color VGA/SVGA displays with
resolution of up to 1280 x 1024 (256 colors). However, since the video controller outputs
only analog signals for CRT display, it will not drive TTL level signals. This means it
does not function with CGA, EGA and Hercules monitors.

7.01.2 DISABLING VIDEO

The video controller can be disabled by removing the W4 jumper. See Section 3 for
jumper location and settings.

This feature is useful when an external video card is required for testing or other purposes.

Installing Video 7-1

7.02 CONNECTING CRT VIDEO DISPLAY

Connecting CRT video to the VIPer808 is simple. Merely connect the standard VGA
DB15 male connector to the board's J12 high density, right angle, female connector. See
Diagram 7-1 on the following page for the location of J12.

POWER MANAGEMENT

8.01 POWER SUPPLY SOURCE

The VIPer808 is powered from one of two sources:

• Power connector (J9): Stand-alone systems are powered from an outside power

supply

through the J9 connector.

• ISA (AT) bus: When the board is in a passive backplane system, it is

powered

through the ISA bus.

The pinout for the J9 power connector is shown in the table below:

Pin Number Signal

2 GND

3 GND

4 +12V

5 -12V

6 PD (Power Fail Detection Input)

Power Management 8-1

8.02 POWER MANAGEMENT MODES

The VIPer808 supports a very flexible and powerful power management scheme. The
System Controller provides progressively higher levels of power conservation whenever
the system is idle through the following special power saving modes: Doze Mode, Sleep
Mode and Suspend Mode (power management test results are given in Table A-2 on page
A-2). These modes are fully programmable through the AMIBIOS Setup Program.

The CPU power consumption is reduced through the STOPCLOCK protocol, which is
used to shut down the CPU’s internal clock during the various power management modes.
In general, each progressive level of power management is entered when inactivity is
detected by the System Controller which monitors activity from the Keyboard, Video,
Serial and Parallel I/O, and the Hard and Floppy Drives.

The timeouts which are used to enter into Doze Mode, then Sleep Mode, and finally
Suspend Mode, are programmable via the AMIBIOS Power Management Setup screen.
Each mode is described below.

8.02.1 DOZE MODE

The Doze Mode is the System Controller’s first level of power conservation. During Doze
Mode, the display and hard drive will remain active. In fact, this mode is transparent to
the user. Exit from Doze Mode is by a keypress or a serial port interrupt (e.g., mouse
movement). Exit from Doze Mode is immediate.

8.02.2 SLEEP MODE

The Sleep Mode is the System Controller’s second level of power conservation. During
Sleep Mode, the display becomes inactive and the hard drive motor is stopped. Exit from
Sleep Mode is by a keypress or a serial port interrupt (e.g., mouse movement). Exit from
Sleep Mode takes approximately 5 seconds.

8.02.3 SUSPEND MODE

The Suspend Mode is the System Controller’s third and deepest level of power
conservation. During Suspend Mode, the display and the hard drive motor remain
inactive. Exit from Suspend Mode is via a contact closure on the J16 Suspend / Resume
Momentary Switch Connector (see Diagram 7-1) or via the RING signal from an external
modem. Thus, if Suspend Mode is to be used, a Normally Open momentary switch should
be connected to this connector. Exit from Suspend Mode takes approximately 7 seconds.

Power Management 8-2

8.03 RESET CIRCUIT

8.03.1 EXTERNAL RESET CIRCUIT SWITCH

The VIPer can be reset by activating an external reset switch.

This switch should be connected between pin 13 (PBRES*) and pin 14 (GND) on the
Keyboard / Speaker Connector (J3).

This provides an easy and effective way of resetting the system.

See Section 4.04 for more information.

8.03.2 ONBOARD POWER DETECTION

An onboard device, which is part of the reset circuit, constantly monitors the voltage
which powers the board. Normally, the board is powered with 5V; if the supply voltage
drops below 4.65V (a typical threshold), the onboard circuitry will reset the VIPer board
and the system. This reset has the same effect on the system as the reset button.

Power Management 8-3

8.04 POWER FAIL DETECTION CIRCUIT

The Power Failure Detector always monitors:

• The backup battery to warn of a low battery condition, and

• The +5V power supply to detect when it falls below 4.75V.

If either of the two above conditions occur, the PFO (Power Fail Output signal) goes low.
In the case of the +5V power supply, a reset will result as explained in the previous
section (8.03.2). In the case of the low battery, what happens will depend on the setting of
the W21 jumper and user-defined algorithm.

The W21 jumper, when shorted, will generate a NMI (Non Maskable Interrupt), through
the IOCHK* line, when the PFO goes low. In turn, this NMI may be serviced by an
interrupt handler to locate the source and notify the user or the system.

If the W21 jumper is left open, no NMI is generated, however an algorithm could be used
to detect a low battery condition and respond accordingly. An example of such an user­defined program appears below.

INDEXREGISTER = 0x24;
DATAREGISTER = 0x26;

boolean Good;
word Data;

outport( INDEXREGISTER , 0x111 ); Set bit 13 Pin Select Register to Low;
Data = inport( DATAREGISTER ); that sets the GPIO1 pin to Enabled.
Data = Data &(~0x2000); Mask on bit 13.
outport( INDEXREGISTER , 0x111 );
outport( DATAREGISTER , Data );

outport( INDEXREGISTER , 0x007 ); Set bit 15 Gen. Purp.Ctrl Reg. to High;
Data = inport( DATAREGISTER ); that puts the GPIO1 pin in Input.
Data = Data &(~0x2000); Mask on bit 15.
outport( INDEXREGISTER , 0x007 );
outport( DATAREGISTER , Data );

Read the PF0 signal …

outport( INDEXREGISTER , 0x007 ); Read the GPIO1 signal (Pwr Fail 0utput).
Data = inport( DATAREGISTER ); If Good is True then the battery is OK,
If (Data & 0x200) Good = True; else the battery voltage is Low.
else Good = False;

Power Management 8-4

The W22 jumper is used to select whether the battery is onboard (1-2) or external (2-3).

The W23 jumper is used to select what voltage is monitored:

• Short pins 1-2 to monitor an external voltage that is present on the power fail input,
through pin 6 of the J9 power connector,

• Or short pins 2-3 to monitor the internal/external battery.

There are three ways to set the Power Fail and Battery circuit:

• Using Internal Battery & Monitoring External Source:
Internal Battery (set by W22 jumper with pins 1-2 shorted) and External Power Fail
Input to Pin 6 of J9 connector (set by W23 jumper with pins 1-2 shorted).

The power detection input can only accept DC voltage. The line is monitored via a
resistor network made up of a user-defined resistor (R98) and a fixed 1KΩ resistor
connected to GND. The junction of these two resistors is connected to the input of the
power fail circuit which has its threshold set to 1.25V. R98 can be calculated as
follows:

R98 = 1KΩ (VI-1.25) where VI is input voltage on pin 6

1.25 of the power connector.

• Using Internal Battery & Monitoring Internal Battery:
Internal Battery (set by W22 jumper with pins 1-2 shorted) and Power fail detect when
battery is less than 3V (set by W23 jumper with pins 2- 3 shorted).

When the internal battery is selected as being the source of the power fail circuit, it is

set to trip when the battery goes lower that 3V.

• Using External Battery & Monitoring External Battery:
External Battery (set by W22 jumper with pins 2-3 shorted) and Power fail detect when
battery is less than 3V (set by W23 jumper with pins 2-3 shorted).

When the external battery is selected as being the source of the power fail circuit, it is

set to trip when the battery drops below 3V.

This means that when an external battery is used, the voltage needs to be monitored on the
battery.

Jumper locations and settings are illustrated in Section 3.

8.05 WATCHDOG TIMER

The Watchdog Timer is extremely useful in embedded systems where human supervision
is not required.

Following a reset, the Watchdog is always disabled. If a hardware or software failure
occurs such that the Watchdog is not refreshed, a reset pulse is generated by the Watchdog
to restart the processor.

Jumper W20 must be installed to permit activation of the Watchdog. If jumper W20 is
removed, the Watchdog is disabled.

An user-defined program such as the one appearing below, must also be used in order to
enable and refresh the Watchdog.

INDEXREGISTER = 0x24;
DATAREGISTER = 0x26;

word Data;

outport( INDEXREGISTER , 0x111 ); Set bit 15 of Select Register to Low;
Data = inport( DATAREGISTER ); that sets the GPIO3 pin to Enabled.
Data = Data &(~0x8000); Mask on bit 15.
outport( INDEXREGISTER , 0x111 );
outport( DATAREGISTER , Data );

outport( INDEXREGISTER , 0x007 ); Set bit 15 Gen. Purp. Ctrl Reg. to High;
Data = inport( DATAREGISTER ); that puts the GPIO3 pin in Output.
Data = Data | 0x8000; Mask on bit 15.
outport( INDEXREGISTER , 0x007 );
outport( DATAREGISTER , Data );

Every 1.6 second (at least), toggle the bit 11 of the GPIO3 pin.

outport( INDEXREGISTER , 0x007 ); Toggle GPIO3 pin for the Watchdog;
Data = inport( DATAREGISTER ); that puts the GPIO3 pin High or Low.
Data = Data ^ 0x800; Toggle bit 11 with XOR.
outport( INDEXREGISTER , 0x007 );
outport( DATAREGISTER , Data );

To disable the Watchdog, just put the bit 15 of the General Purpose Control
Register Low.

Power Management 8-6

The default timeout period is 1.6 seconds; however the timeout period can be changed.
Shorting C173 and leaving R165 opened changes the timeout to 100 ms. Shorting R165
and installing a capacitor at C173 will change the timeout period according to the
following formulae:

Timeout (milliseconds) = (400/47pF) * C
or
C173 = (Timeout (milliseconds) * 47pF) / 400ms

For instance, an external capacity of 100pF will lengthen the timeout to 851ms and a
1000pF will bring it to 8.5 seconds.

SECTION 9
VIPer SOFTWARE SETUP

The VIPer808 is fully software configurable. The setup program allows for minimal
hardware configuration.

The AMIBIOS Setup program which is used to change operating parameters is explained
in section 9.01.

The procedure for updating or restoring the VIPer808 BIOS in the Boot-Block Flash is
given in section 9.02.

VIPer Software Setup 9-1

9.01 AMIBIOS SETUP PROGRAM

9.01.1 ACCESSING AMIBIOS SETUP PROGRAM

The VIPer808 uses the AMIBIOS Setup program, a setup utility in ROM that is accessed
by pressing the DELETE key at the appropriate time during system boot. This utility is
used to set configuration data in CMOS RAM.

The system BIOS (Basic Input Output System) provides an interface between the
operating system and the hardware of the VIPer808 single-board computer. The interface
provided by AMIBIOS is 100% IBM AT compatible: All functions accept similar inputs
as IBM and provide the same results, although the program code itself is different.

To run the AMIBIOS Setup program incorporated into the ROM BIOS:

• Turn on or reboot the system.

• Hit the DELETE key before or when the message - "Hit <DEL> if you want to run
SETUP" appears near the top of the screen (DELETE will work, even if the message
display is disabled in AMIBIOS SETUP).

• The main menu appears on the screen.

VIPer Software Setup 9-2

9.01.2 AMIBIOS SETUP MAIN MENU

The main menu screen looks as follows:

Four windows appear on the above screen:

• Setup window (explained in section 9.01.4)

• Security window (section 9.01.5)

• Utility window (section 9.01.6)

• Default window (section 9.01.7).

The Setup window is highlighted on the screen displayed above, meaning that you can
select items in that window. To highlight the other windows, press the TAB key on the
keyboard, or if a supported mouse1 was detected, move the arrow cursor over the desired
window, and click the left mouse button.

F Press TAB to select a window (Setup, Security, Utility, or Default) or click the

mouse inside that window.

All PS/2-type mice are supported, as well as bus mice that use IRQ 3, 4 or 5 (not

2), Microsoft-compatible mice (M, V, W Series), Logitech C-series-compatible
mice and many serial mice.

VIPer Software Setup 9-3

9.01.3 MAKING SELECTIONS, SAVING CONFIGURATIONS &

EXITING AMIBIOS SETUP

MAKING SELECTIONS

Each of the windows displayed in the main menu screen contains icons (small drawings
under which an identifying label appears). For example, the Setup window has the
following icons and labels: Standard, Advanced, Chipset, Power Mgmt, PCI/PnP and
Peripheral. Each of these icons corresponds to various setups available within AMIBIOS
Setup, i.e. the Standard Setup, the Advanced Setup, the Chipset Setup, the Power
Management Setup, the PCI/PnP Setup and the Peripheral Setup. Selecting one of these
icons gives access to the corresponding Setup and its options.

To select an icon within a window, you must press one of the arrow keys on the keyboard
until the desired icon is highlighted, and then press the ENTER key, or move the mouse to
highlight the icon and click the left button to select. This method of selection basically
applies for all selectable items (icons, options, and settings).

F Icons, options and settings are selected by using one of the arrow keys to highlight

the desired item, then by pressing the ENTER key, or by clicking the mouse over
the desired selection.

The windows in the program have layers, like boxes inside boxes. Selecting an icon, may
display another window with icons; in turn, selecting one of these icons can display a
window which contains a list of options. Selecting an option will in turn open a window
containing a list of possible settings. To return to a previous window, you press the ESC
key on the keyboard, or click the small box on the top left corner of the window.

F To close the current window and move to the previous window, press the ESC key

or click the small box on the top left corner of the window.

Mostly all selections and settings will be done using the special keys (TAB, ESC, →, ←,
↑, ↓ and ENTER) or using the mouse’s left button. There are a few exceptions, for

example while entering the date and time (Standard Setup option), you need to use the +
or - keys or click the + or - boxes to change the values. Another example is when
characters need to be entered at the keyboard, such as a password (a window appears
which ressembles a keyboard; as you enter the characters, "*" is displayed for each
character entered; then to accept the password, press ENTER).

VIPer Software Setup 9-4

SAVING CONFIGURATIONS & EXITING AMIBIOS SETUP

If you press the ESC key from the main menu screen or click the small box on the upper
left corner of one of the main menu windows, an EXIT SETUP window appears.

The EXIT SETUP window displays the following options:

• Save changes and Exit

• Do not save changes and Exit

• Continue

Each is explained below:

Save changes and Exit

After having modified the AMIBIOS Setup, you can save the configuration in CMOS
RAM, by selecting this option. After the information is saved, the computer is
automatically rebooted. This option will not change the default values saved in Boot-Block
Flash.

Do not save changes and Exit

This option is used to exit AMIBIOS Setup without saving the configuration to CMOS
RAM.

Continue

To return to the main menu without saving or exiting, select this option.

F To save changes and write the new configuration to CMOS RAM, select the "Save

changes and Exit" option from the EXIT SETUP window.

The four windows of the main menu, will now be described in the remainder of this
section.

VIPer Software Setup 9-5

9.01.4 SETUP WINDOW

This section describes the six options of the Setup Window. These are:

• Standard Setup: offers the options to set the time, date, hard disk parameters, and
floppy drives.

• Advanced Setup: handles options and features such as key repetition settings, boot
sequence, NUM LOCK and password checking, shadowing, ...

• Chipset Setup: sets chipset-specific options and features.

• Power Management Setup: sets power conservation options.

• PCI/PnP Setup: sets the Plug and Play related options.

• Peripheral Setup: sets I/O controller-related options.

VIPer Software Setup 9-6

STANDARD SETUP

This part of the setup allows you to set the time, date, hard disk type, types of floppy
drives, monitor type, and whether the keyboard is installed.

The Standard Setup screen displays seven icons as follows:

Pri Master Sec Master
Pri Slave Sec Slave

These four hard disk drive icons are for configuring hard disks connected to the VIPer808
or to a peripheral board. Select the appropriate hard disk drive icon (Pri Master = C:
drive).

For each hard disk, these options can be defined: TYPE, LBA/LARGE MODE, BLOCK
MODE, 32BIT MODE and PIO MODE. TYPE and PIO MODE can be Auto detected if
the hard disk drive is an IDE drive: the Auto option automatically finds all of the IDE
drive parameters for that hard disk. You should check your hard disk data sheets to know
if any of the other options - LBA/LARGE MODE, BLOCK MODE and 32BIT MODE ­should be set to ON; if your hard disk supports these modes, enabling them will optimize
your system.

F It is possible that the parameters provided by Auto detection do not match the

ones found in your drive's literature. This should not be considered an error. As
a matter of fact, different combinations of heads, cylinders and sectors that
match the disk's size will work when formatting an IDE hard drive. But if the
disk is already formatted, it is not possible to use different parameters than the
ones that were used when the drive was originally formatted.

Date/Time

The current values for each category are displayed. To change the date or time, highlight
the values you want to change, and press the + or - key or click the + or - box, until the
desired value is displayed.

Floppy A
Floppy B

The settings are: 360KB 5¼ inch, 1.2MB 5¼ inch, 720KB 3½ inch, 1.44MB 3½ inch,

2.88MB 3½ inch, or not installed.

VIPer Software Setup 9-7

ADVANCED SETUP, CHIPSET SETUP, POWER MANAGEMENT SETUP, PCI/PNP
SETUP & PERIPHERAL SETUP

The Advanced Setup, Chipset Setup, Power Management Setup, PCI/PnP Setup and
Peripheral Setup are described in the following pages with both Fail-Safe Defaults and
Optimal Defaults values.

Whenever you are not sure about a certain setting, you may refer to the list of default
values. The list of defaults is provided in the event that a value has been changed and one
wishes to set this option to its original value. Loading the Optimal or Fail-Safe defaults
will affect all the options and will reset options previously altered.

The Fail-Safe default settings consist of the safest set of parameters. Use them if the
system is behaving erratically. They should always work but do not provide optimal
system performance.

The Optimal default values provide optimum performance settings for all devices and
system features.

These default values have been provided to give control over the system. However, the
values for these options should be changed only if the user has a full understanding of the
timing relationships involved.

does not test memory above 1MB and does not wait up to 40 seconds for a READY signal from the IDE hard drive (as a result,
AMIBIOS does not configure that drive if a READY signal is not received immediately).

This option specifies the boot sequence for drive A:, C:, CDROM after AMIBIOS POST completes and attempts to boot DOS. When
booting from the CDROM drive, the CDROM behaves like drive A: if it has a floppy boot image. The CDROM drive now becomes drive
A: and the first floppy drive becomes drive B:. On the other hand, the CDROM behaves like a hard drive if the CDROM has a hard disk
boot image. The CDROM drive now becomes drive C: and all other hard drives are shifted one letter (the hard disk drive becomes drive
D:).

If this option is set to Off, the NUM LOCK key on the keyboard is turned off when the system is powered on; you can use the →, ←, ↑,
↓ keys on both the numeric keypad and the keyboard.

By enabling this option, floppy drive A: becomes drive B:, and drive B: (if present) becomes drive A:. Thus you are allowed to boot from
drive B:.

C800, 16K SHADOW option enables shadowing of the contents of ROM from C8000h-CBFFFh to RAM.

Not all BIOS can be shadowed. In some cases, it can result in erratic operation. For example, if the expansion board has
built-in “scratchpad memory”, which is used internally, shadowing may cause unpredictable results.

When the Supervisor or User icon is selected from the Security window in the main menu,
the user can enable the password feature or change the password itself. By default, the
user can boot the system and enter the AMIBIOS Setup without any restrictions. Choosing
a password for the first time will automatically enable the password feature. At the next
bootup, the user will be prompted to enter his password on bootup or when he attempts to
enter AMIBIOS Setup, depending on the setting of the PASSWORD CHECK option in
the ADVANCED SETUP (see the PASSWORD CHECK option description for the
available settings).

F To disable the password, use this option: 1) At the prompt "Enter CURRENT

Password", enter your password, 2) Then at the prompt "Enter NEW Password",
press ENTER, 3) Then at the prompt "Confirm NEW Password", press ENTER,

4) The screen then displays "Password uninstalled". Make sure you select Save
Changes and Exit from the EXIT SETUP window. If you forget your current
password, the password feature can be disabled by removing jumper W22 for
several minutes; however this will also clear the CMOS Setup, which will then be
configured at the BIOS default values.

SUPERVISOR

This option allows you to enable the main password of the supervisor user. You must set a
supervisor password before attempting to set user passwords. If you disable this password,
all user passwords will automatically be disabled as well.

saved in the CMOS Setup; it will be used to restore the values saved in
CMOS, after a number of settings have been changed in the AMIBIOS
Setup program.

• Optimal: This option allows you to load the Optimal Default values. These are
common recommended values and should optimize system performance.
This feature might be useful in instances where a quick reconfiguration is
needed.

• Fail-Safe: This option allows you to load the Fail-Safe Default settings. These are

worst-case values that are the most stable values that can be chosen. Use
this option as a diagnostic aid if the system is behaving erratically.

9.02 UPDATING OR RESTORING BIOS IN BOOT-BLOCK FLASH

The Boot-Block Flash device contains a non-erasable boot-strap loader which can
reprogram the device with a BIOS file from a floppy drive diskette.

All VIPer808 BIOSes are stored in the file SEQ256.BIN in the Boot-Block Flash device.
For the Main BIOS (AMIBIOS), only the default values are stored (fail-safe and optimal)
in Boot-Block Flash; therefore if changes are made to the settings, these will not be saved
in the Boot-Block Flash BIOS file.

If you need to update or restore the VIPer808 BIOS file SEQ256.BIN in the Boot-Block
Flash, follow this procedure:

1. Turn off your computer system.

2. Place diskette with SEQ256.BIN file in drive A. Make sure the SEQ256.BIN file is on

the diskette.

3. Hold the CTRL and HOME keys simultaneously and power on your computer system.

Release the CTRL-HOME keys after a few seconds.

4. After the three audible beeps, remove diskette from drive A. Boot-up will proceed.

The Boot-Block Flash BIOS is now updated or restored.

VIPer808 Specifications A-2

A.02 BATTERY

The VIPer808 comes with a 360mAh TL5186 TADIRAN battery. It powers the System
Controller’s Real Time Clock and CMOS Setup, whenever the board is powered down.

The TADIRAN TL5186 has a shelf life of approximately 10 years (under "no-load"
conditions). The actual life of the battery depends on environmental (temperature)
conditions. The TADIRAN TL5186 has an operating range of -55o to 75°C and discharge
characteristics vary with temperature.

The voltage supplied by the battery is 3.6 volts. This can be verified with a standard
voltmeter at the battery socket’s two extreme pins (if you use the pin on the soldered side,
you do not have to remove the battery).

The TADIRAN TL5186 is UL recognized. Its UL component recognition is MH12193.

Jumper W22 enables the Internal Battery’s power. Removing the W22 jumper has the
same effect as putting the battery in storage; TEKNOR always ships its board with battery
jumper removed in order to increase the life of the battery.

An External Battery may be used. In such a case, pins 2 and 3 of jumper W22 should be
shorted.

Please refer to Section 3 for jumper location and setting.

The MTBF is estimated using the prediction data from MIL-HDBK-217F, Reliability
Prediction of Electronic Equipment (Dec. 1991).

The VIPer808 board is considered functioning in a Ground Fixed environment as defined
in MIL-HDBK-217F. The calculations are performed at 20°C with a temperature rise of
10°C which is due to heat dissipated by active components.

It is assumed that only one failure at a time can occur and that the failure of any
component will result in the system becoming inoperative or, as a minimum, resulting in
a degraded mode of operation requiring repair action. All components are considered as
having an exponential distribution of time to failure, with a constant failure rate. A failure
rate is attributed to each component called in the parts list, according to the stress levels it
is submitted during normal operation.

VIPer808 Specifications A-4

The components with the highest calculated failure rate in the VIPer808 reliability
prediction are: the 486 CPU, the SVGA (GD5429), the Sequoia chip set (PT86C718) and
the chip set (PT86C768).

The quality factors for commercial components on the VIPer808 has been adjusted in
order to represent the impact of burn-in. TEKNOR submits each processor board produced
to a 12 hour burn-in at 40°C. The boards are powered during this phase to precipitate
latent failures. It is well known that a burn-in performed under these conditions improves
board and component quality. Since there is a correlation between quality and reliability,
it is generally accepted in the industry to reflect this in the reliability prediction.

VIPer808 Specifications A-5

A.04 MEETING INDUSTRY STANDARDS

TEKNOR Quality Standards insist that our products meet or exceed industry standards set
by such respected agencies, organizations and associations as UL and CSA.

As a result, the VIPer808 has the following built-in features to help ensure that the
conditions required for approval are met:

• A current block diode on the battery circuit,

• A current limiter resistor on the battery,

• A protection fuse on the keyboard controller.

TEKNOR computer cards are designed to meet industry standards for customers requiring
approval for their equipment.
