System Overview
Introduction
Welcome to Multi-Techs new MultiVOIP Gatekeeper, Model MVPGK1, a turnkey hardware and
software solution that enables network managers and intranet managers to define and control how
H.323 voice traffic is managed over IP networks. The MultiVOIP Gatekeeper is a complementary product
to the MultiVOIP 200 (MVP200), the 2-Voice/Fax channel product and the MultiVOIP 400/800 (MVP400),
4-Voice/Fax channel product, and the MVP800, the 8-Voice/Fax channel product. The MultiVOIP
GateKeeper is an industry-standard mechanism for call control and routing, basic telephony services,
H.323 bandwidth usage control, total network usage control, and overall system administration and
security policies. It includes fast, easy-to-use interfaces that network managers can use to modify or
update zone configurations when an individual on the network needs additional services. And, it
provides call centers with the capability to perform needs-based call routing as well as providing a
variety of other automatic call distribution features.
The MultiVOIP GateKeeper is a ruggedized, expandable, 19-inch rack mount unit that includes a built-in
hard drive, a 3.5-inch floppy drive, and a CD-ROM drive. Its removable card cage has six circuit board
slots: one slot on the lower left side of the card cage is dedicated to the single-board computer (SBC);
also, there is one combo slot (PCI or ISA) and four PCI slots.
The IPC-551 SBC is a full size plug-in PC board with PCI bus architecture, a 233 MHz processor, 256 MB
of DRAM, Award BIOS, and Green PC functions that enable the computer to operate at a decreased
power level after it senses a period of idleness. In one of the PCI slots is an EN10100PCI Ethernet
adapter card that is a Plug and Play device with data transfer rates of either 10 Mbps (Ethernet) or 100
Mbps (Fast Ethernet), selected via auto-negotiation.

Windows operating system and Gatekeeper software, and is ready to be connected to an Ethernet
concentrator. The operator needs only to connect a VGA (or SVGA) monitor, keyboard, Ethernet cable,
and mouse, boot the system, and enter some basic information. To connect the cables to a monitor and
keyboard, see the Cable Connections section of this chapter.
Unpacking
Check the items on the Gatekeeper shipping list to ensure that you have received the correct options
and accessories. Unpack the unit and inspect it for visible shipping damage. If damage is observed, do
not power-on the unit; contact Multi-Tech's Tech Support for advice. If no damage is observed, place
the Gatekeeper in its final location.
Safety Warning AC Power
Locate the AC outlet near the communication equipment. The AC power cord is your main AC
disconnecting device and must be easily accessible at all times. For your safety, the power cord
provided with your system has a grounding plug. Always use the power cord with a properly grounded
wall outlet to avoid the risk of electrical shock.
Lithium Battery Caution
A lithium battery on the product provides backup power for the devices timekeeping capability. The
battery has an estimated life expectancy of ten years.
When the battery starts to weaken, the date and time may be incorrect. If the battery fails, the unit
must be sent back to Multi-Tech Systems for battery replacement.
Warning: There is danger of explosion if the battery is incorrectly replaced.
Laser Safety Caution

Powering Up
Note: This is pluggable equipment; the socket outlet must be installed near the equipment and must
be easily accessible.
When connecting the equipment to the power-supply circuit, be sure to check equipment nameplate
ratings to avoid overloading circuits. Overloaded circuits may cause damage to over-current protection
devices and to power-supply wiring.
Make sure that the voltage selector on the power supply is set to the proper voltage prior to connecting
this equipment to the main power. If the voltage selector needs to be changed, an ordinary pencil can
be used to change the switch to the position which best correlates with the known input voltage. If the
voltage selector is in the "115" position, input voltages from 100-120VAC may be applied to the
equipment. If the voltage selector is in the "230" position, input voltages from 200-240 VAC may be
applied to the equipment.
Connect the power cord supplied with the CommPlete 4000 to the power cord connector on the back of
the cabinet and to an AC outlet. Press the power switch on the front of the cabinet to the ON position.
The power switch contains an LED which should light when power is applied.

Introduction
This chapter introduces some of the features of the Multi-Tech Single Board Computer (or SBC), Model
IPC-551, used in the Gatekeeper. Further details can be found in Appendixes A, B, and C.
About the SBC
The IPC-551 SBC is a full size plug-in PC board with PCI bus architecture, a 233 MHz Intel Pentium
processor with MMX, 256 MB of dynamic random access memory (DRAM), Award PnP flash ROM BIOS,
a watchdog timer, and a Green PC function that enables the system to operate at a decreased power
level after it senses a period of inactivity.
The memory interface on the SBC consists of four 72-pin single in-line memory module (SIMM) sockets
(two double DRAM banks) that can be used to configure memories ranging from 8MB to 256 MB.
(Details are provided in Appendix C.) The 256 MB memory supplied with each Gatekeeper consists of
four 64 MB memory modules.
The system BIOS and VGA BIOS on the SBC can be updated as necessary using the Awdflash.exe
program provided on the system CD-ROM. (Details are provided in Appendix C.)
A watchdog timer (WDT) is provided on the SBC in case your system configuration requires that the
Gatekeeper be remotely rebooted from time to time. Setup instructions for the WDT are also provided
in Appendix C.)
The default condition for the Green PC function on the SBC board is Off. When activated, however,
the green function slows down the Gatekeeper and shuts down certain computer functions in order to
reduce power consumption. The three reduced-power operating modes built into the green function
are: CPU Doze mode, System Standby mode, and System Suspend mode. See Appendix C for further
details concerning the Green PC function.

Introduction
This chapter documents the features and specifications for the Multi-Tech EN10100PCI (NIC board), a
10/100Mb Ethernet PCI bus NIC with Auto-negotiation (Figure 4-1).
Figure 4-1. NIC Board
About Fast Ethernet
Fast Ethernet is a network technology specified by IEEE Standard 802.3u. It extends the traditional
10Mbps Ethernet technology to achieve 100Mbps transmission and reception, while retaining the same
CSMA/CA Ethernet protocol. Thus while Fast Ethernet provides a tenfold increase in network capacity,
it is wholly compatible with traditional 10Mbps Ethernet network facilities. This compatibility is the key
to easy and efficient upgrades to 100Mbps in your network areas needing greater bandwidth.
Upgrading selected areas to Fast Ethernet does not require hardware or software changes in network
areas where traditional 10Mbps Ethernet is providing good service. For upgrading existing Ethernet
installations to 100Mbps, and especially for selectively upgrading areas needing upgrade, Fast Ethernet
is the clear choice in terms of cost-effectiveness, as well as convenience and smoothness in transition.
Fast Ethernet comprises two subtypes: 100Base-T4 and 100Base-TX. 100Base-T4 Fast Ethernet can
use existing Category 3 or Category 4 UTP network cabling, but does not provide full duplex operation.
100Base-TX requires Category 5 cabling, but does provide full duplex operation. Full duplex 100BaseTX operation enables simultaneous transmission and reception, both at 100Mbps, thus providing
service potentially equivalent to 200Mbps half-duplex service. The EN10100PCI Adapter does not
support the 100Base-T4 subtype. To provide compatibility in traditional 10Mbps Ethernet environments
(where, for example, EN10100PCI adapters are installed anticipating upgrade of supporting hub
equipment to Fast Ethernet), the EN10100PCI also supports traditional 10 Mbps Ethernet operation, in
full-duplex as well as half-duplex modes. Selection of the best operation mode in any given installation
is automatically governed by auto-negotiation.
About Auto-negotiation
You have probably had the experience of making a dialup connection through a modem, and have
heard the gravelly-sounding exchanges between your modem and the modem at the other end of the
telephone line (these exchanges are ordinarily played out through a speaker in your local modem). As
irritating as those few seconds of noise may be, they do let you know that your modem and the remote
modem are on the job, preparing for your intended communication with the remote computer. The
preparatory work of the two modems during those few seconds before you see the Connect message
is to negotiate the best data communication scheme which is supported by both modems, and which is
24 MultiVOIP Gatekeeper User Guide
Page 25
Chapter 4 - PCI NIC Board
suitable for the quality of the telephone line linkage between them. The parameters to be settled
between the two modems include best baud rate, compression method, and error correction method.
When the two modems have tested the phoneline quality and settled on the combination of shared
options and parameters which will provide the best data communication over the connecting phone
line, then you are given the Connect message which signals the end of the intermodem negotiation
and the beginning of your intended communication with the remote computer.
Auto-negotiation between devices within an Ethernet LAN is similar in concept, but much briefer. The
two devices involved in the auto-negotiation will be the EN10100PCI Adapter serving your station and
the hub through which it is connected into the LAN. The options to be negotiated between the
EN10100PCI and its supporting hub include Ethernet type (100BASE-TX Fast Ethernet or 10BASE-T
Ethernet) and duplex mode (half-duplex, being one-way-at-a-time, or full duplex, being simultaneous
transmit-and-receive). Startup communication between the two devices occurs when both devices are
power-on, the cable connection between them is good, and the Network Operating System software is
running. As soon as those conditions are satisfied, the preparatory process of auto-negotiation between
the EN10100PCI and its supporting hub proceeds automatically. If the hub has auto-negotiation
functionality, then it and the EN10100PCI exchange a series of messages in which each device signals
its capabilities and listens for corresponding information about the other. The auto-negotiation process
requires only a few milliseconds, and the two devices select the best communication parameters
supported by both devices. If the hub does not have auto-engotiation functionality, then its monotone
(single capability) message will be recognized by the EN10100PCIs auto-negotiation facility, and the
EN10100PCI will simply switch to one of its own capabilities which matches that of the hub.
When the preparatory procedure of auto-negotiation is completed, then the line is ready and will
provide a data channel which is optimal for the two devices. The line will remain ready without further
auto-negotiation action until the linkage is broken. Auto-negotiation then reoccurs at any time that the
linkage is restored, again making the line ready for optimal data communications.
About PCI Bus
Your EN10100PCI Adapter delivers outstanding performance by fully exploiting the advanced features of
your computers PCI bus. EN10100PCI Adapters utilize the Bus Master Mode of the PCI bus, enableing
direct transfers of Ethernet packet content between computer memory and the adapters controller,
thus minimizing network demand on the CPU. The adapters controller function provides the additional
benefit of reduced command processing overhead. The working relationship between a EN10100PCI
adapter and main memory working in Bus Master mode is powered by the Bridge/Memory Controller of
the PCI bus. This reduces the CPU role in network operations, thus freeing the CPU to service other
tasks, with resulting improvement in overall computing (multitasking) performance. At the same time, it
produces superior network throughput by reducing latency (waiting for CPU service) during
transmissions and receptions.
Features
Designed for versatility and performance, the EN10100PCI Adapter provides the following features:
· Operates in a PCI Bus Master slot of a Pentium computer, independent of CPU speed.
· PCI Bus Master memory access, for high throughput and low CPU demand.
· 32-bit Intelligent Ethernet controller.
· Complies with IEEE 802.3 100Base-TX and 10Base-T Ethernet standards.
· Plug and Play installation.
· RJ-45 connector for network cable connection.
· 100Mbps Fast Ethernet or 10Mbps Ethernet data transfer, selected via auto-negotiation.
MultiVOIP Gatekeeper User Guide 25
Page 26
· Full duplex or half-duplex operation, selected by auto-negotiation.
· Built-in FIFO buffers reduce overhead of memory transfers.
· Three LED indicators: 10Mbps/100Mbps, Link, Activity.
· Drivers for all leading Network Operating Systems.
LED Indicators
The EN10100PCI Adapter features three LED indicators to assist in the resolving of network diagnostics:
· 10Mbps/100Mbps SPEED Indicator
This LED shows steady green (on) when 100Mbps speed is selected. It is dark (off)
when10Mbps is negotiated.
· LINK Indicator
Steady green indicates good linkage between the EN10100PCI and its supporting hub.
· ACTIVITY Indicator
Flashing green indicates that the adapter is sending or receiving.

6 Troubleshooting
Page 36
Introduction
This section provides a variety of approaches should the Gatekeeper fail to operate properly. Your
Gatekeeper was tested thoroughly at the factory before it was shipped. If you are unable to make a
successful connection, it is possible that the Gatekeeper is defective. However, it is more likely that the
source of your problem lies elsewhere. As with any microcomputer product, start with simple hardware
and software problems and work toward more complex problems (e.g., operating system and/or
applications).
Hardware Troubleshooting
The following material addresses some of the typical problems and provides some basic solutions. If a
problem arises while you are in an application, see the software documentation.
No Video
Verify that power is ON (LED in power switch is lit).
Verify that the SBC and NIC adapter board are connected properly.
Note: Make sure to turn power OFF to reconnect boards.
Verify that monitor is turned ON, power is connected to monitor, and video cable is
connected to video connector on SBC.
Verify that the two (or four) 72-pin memory SIMMs are connected properly on the SBC.
The SIMMs must be the same brand, type, size, and speed.
Disconnect all cables (except the video cable) from the SBC and NIC board, then power
ON the Gatekeeper . If the Gatekeeper now has video, then there is a problem with one
of the cables or one of the peripherals. Try each cable, one at a time, to isolate the bad
cable or peripheral.
Verify that blower fans are running. If power is on and a fan is stopped, check to be sure
power connectors from power supply to midplane are fully connected and in their proper
orientation, as shown on Figure TBD.
If problem persists, contact MultiTech's Technical Support department (see Chapter
TBD).
SBC does not boot correctly or hangs after video appears
Run BIOS Setup Utility to verify correct configuration for system and drives (i.e., press
DEL key as system boots to enter BIOS Setup).
If boot PROM is used, verify that network and NIC board are configured properly to see
the network.
Verify that SBC and NIC board are seated properly in backplane.
Note: Make sure to turn power off to reconnect boards.
Drive cables are not connected properly or parameters are not set properly in setup.
If a non-bootable diskette is in the floppy drive, remove it and try booting
again.
Verify that enough memory is installed to load the intended applications.
Verify that two (or four) 72-pin SIMMs are seated properly on the SBC. The SIMMs must
be the same brand, type, size and speed.
Remove NIC board. If system boots then, there was a conflict with the NIC board.
36 MultiVOIP Gatekeeper User Guide
Page 37
Chapter 6 - Troubleshooting
If problem persists, contact MultiTech's Technical Support department (see Chapter 6).
COM1, COM2, or LPT1 port does not respond correctly
Check Setup configuration and verify that the ports are enabled.
Check that cables are connected properly and peripherals are powered ON and
configured properly.
If problem persists, contact MultiTech's Technical Support department (see Chapter 6).
Keyboard does not respond to key strokes
Verify that the keyboard cable is plugged into the left round connector on the SBC.
If a PS/2 keyboard adapter is used to adapt a large 5-pin DIN to a small 6-PIN PS/2 DIN
connector, verify that it is not defective or the wrong type.
Verify that the keyboard works properly on a different system.
If problem persists, contact MultiTech's Technical Support department (see Chapter 6).
Gatekeeper fails during prolonged operation
A power glitch may have occurred.
Check for overheating by verifying that all fans are operating, including two blowers in
the front part of the card cage, CPU fanned-heatsink, and the power supply internal fan.
Verify that air vents surrounding the chassis are not blocked.
Verify that the room housing the Gatekeeper is not overly warm.
Check for possible power surges from other equipment in the room and/or building.
Verify that SBC and NIC board are operating reliably.
Verify that there is not a buildup of dust inside the Gatekeeper.
Check the event viewer in Windows NT Server for errors occurring in the system,
security, or application logs.
Invalid Time, Date or Setup
Battery is failing.
Last system boot was incomplete. Verify in Setup that configuration is correct, then
reboot system.
If problem persists, contact MultiTech's Technical Support department (see Chapter 6).
NIC Board Troubleshooting
If you experience any problems with the NIC board, verify that the appropriate driver is loaded, the
proper grade of cable is used for the network connection, and the supporting hub/switch is working
properly.
1. Make sure the NIC board is fully and firmly seated in the slot connector.
2. Check the length and rating of connecting cables.
3. Make sure the NIC boards PCI slot is activated at the BIOS level. The CMOS Setup utility in
PCI computers ordinarily provides the option to activate or deactivate PCI slots.
MultiVOIP Gatekeeper User Guide 37
Page 38
4. Replace the NIC board in question with a verified good unit, then repeat the diagnostic
tests.
5. Install the questioned NIC board in another PCI computer and repeat the diagnostic tests on it
there.
Diagnostic Tests
The Gatekeeper operates like any stand-alone PC and can run almost any off-the-shelf diagnostic
program or checkpoint card. These programs are available at any software re-seller and can quickly
help isolate component failures.
Troubleshooting with Error Messages
This section outlines errors that may occur during system operation and likely remedies for these
problems.This section describes error messages and their use in troubleshooting. Since many errors
can be caused by poor cable connections, you should first verify that all cables are connected firmly to
their proper receptacles. If error messages persist after the recommended adjustments have been
made, contact Multi-Tech Systems for maintenance.
Post Beep: The BIOS generates two beeping (audible) error codes.
(1) A single long beep followed by three short beeps indicates that a video error has occurred and
the BIOS cannot initialize the video screen to display any additional information.
(2) A single long beep sounded repeatedly indicates that a DRAM error has occurred.
CMOS Battery Failure: If the CMOS battery is low or dead, it should be replaced. Replacement
requires soldering. If the clock fails, return the SBC to Multi-Tech Systems for repair.
CMOS Checksum Error: This error indicates that the CMOS has been corrupted, possibly by a weak
battery. Reconfigure the CMOS settings, then check to see if this is a continuous problem.
Disk Boot Failure: When you cant find the boot device, insert a system disk into Drive A and press <
Enter >. Make sure that the controller and the cables are in their proper positions and that the hard
drive has been formatted correctly. Then reboot the system. Verify the hard drive and floppy drive
selections in the CMOS Setup.
Diskette Drives Or Types Mismatch Error: When the diskette drive type is different from the
settings specified in CMOS (BIOS Setup), run Setup and re-configure the drive.
Error Encountered Initializing Hard Drive: If you cannot initialize the hard drive, check that the
adapter has been installed correctly and that all cables are correctly and firmly attached. Also be sure
the correct hard-drive type has been selected in the BIOS Setup.
Error Initializing Hard Disk Controller: When this error occurs, check to see that the cable
connecting the hard drive to the motherboard is seated properly in its receptacle. Make sure the correct
hard-drive type has been selected in the BIOS Setup. Also, check to see that all of the jumpers in the
hard drive unit have been set correctly.
Floppy Disk Controller Error or No Controller Present: When you cannot find or initialize the
floppy drive controller, please check that the controller settings in the BIOS Setup screen match the
actual controller being used. If no floppy drives are installed in your PC, be sure the Diskette Drive
field of the Setup screen is set to NONE.
Keyboard Error Or No Keyboard Present: When this error message appears, check to see that
your keyboard is attached properly to its receptacle. Make sure JP6 is jumpered for keyboard. Also, be
sure that no keys are being pressed during the booting process. 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: If the memory address indicates an error, use the specified location and the
memory map for your system to find and replace the bad memory chips.
Memory Verifying Error : It indicates an error verifying a value already written to memory. Try
reseating the memory SIMMs or replace them one at a time.
38 MultiVOIP Gatekeeper User Guide
Page 39
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, you must reboot. Press any key and the system will reboot.
System Halted: Indicates that the present boot attempt has been aborted and the system must be re-
booted. Press and hold down the CTRL and ALT keys and press DEL.

How to Set Jumpers
Jumpers and Caps. Your PC is configured by the positions of jumpers on the circuit board. A jumper
consists of two or more metal pins with a plastic base mounted on the card. A small plastic cap (with
a metal contact inside) is used to connect the pins. For two-pin jumpers, the active value for userchangeable parameters depends on jumper pins being closed (electrically connected by a cap) or open
(not electrically connected). For parameters having more than two values, groups of jumpers (or
jumper blocks) are used to determine the active value. For example, if a jumper has three pins
labeled PIN1, PIN2, and PIN3, you can use a jumper cap to connect PIN1 & PIN2 to activate one value
for the parameter. Connecting PIN2 and PIN3 would activate another value.
This manual contains many illustrations of jumper configurations. Jumper caps are depicted as shaded
boxes connecting pairs of pins on jumper blocks

Flash BIOS Update
BIOS updates are revised versions of the BIOS that have been modified to remedy known bugs. When
necessary, use the program Awdflash.exe on your System CD-ROM to update the system BIOS and
the VGA BIOS. Check periodically with MultiTech to see if a new flash BIOS update is available.
Watchdog Timer Configuration
The watchdog timer does not run constantly. It must be started in DOS Debug mode or from another
application program, customized for this purpose, that runs on the system. The watchdog timer is
especially useful for remote rebooting of the PC.
The watchdog timer is defined at I/O port 0443H. To enable the watchdog timer, write I/O port
0443H, then the system will reset itself. To disable the function, write I/O port 0441H and the system
will stop the Watchdog timer.
Since the timers intervals have a tolerance of 25%, you should specify that the timer be refreshed
about once every second. To program your watchdog timer, follow these steps:
Watchdog enable program:
MOV AX, 000FH (choose the values you need; start from 0)
MOV DX, 0443H
OUT DX, AX
Watchdog disable program:
MOV AX, 000FH (this value can be ignored)
MOV DX, 0441H
OUT DX, AX
The Watchdog Timer control table is as follows:
Level Value Time/sec Level Value Times/sec
1 F 0 9 7 16

Green PC Function
The Gatekeeper is equipped with a green function that enables it to operate using reduced electrical
power when the machine is inactive. When in green mode, the Gatekeeper slows down and shuts down
certain computer functions in order to reduce power consumption. There are three reduced-power
operating modes (presented in order of increasing power savings):
(1) CPU Doze Mode,
(2) System Standby Mode,
(3) System Suspend Mode .
By default, however, the green function is turned off.

Award BIOS Setup
This chapter describes how the BIOS manages the features of your system and explains how to
configure the BIOS in its Setup Menu. The IPC-551 single-board computer is equipped with a system
BIOS chipset from Award Software Inc.
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, in turn, relies on a BIOS (Basic Input and Output system), a program stored on a
ROM (Read-only Memory) chip, to initialize and configure your computers hardware. As the interface
between the hardware and the operating system, the BIOS enables you to make basic changes to your
systems hardware without having to write a new operating system.
The following diagram illustrates the interlocking relationships between the system hardware, BIOS,
operating system, and an application program:
Application Program
Operating System
BIOS
System Hardware
Figure C-2. PC Subsystem Relationships
The Setup program built into the Award BIOS lets users modify the basic system configuration. This
special configuration information is then stored in battery-backed RAM so that the PC retains the Setup
information when the power is turned off.
The Award BIOS is a custom version of an industry standard BIOS. It supports Intel/Cyrix/AMD
processors in a standard IBM-AT compatible input/output system. The BIOS provides critical low-level
support for standard devices such as disk drives and serial and parallel ports.
The Award BIOS has been customized by adding important, but non-standard, features such as virus
and password protection as well as special support for detailed fine-tuning of the chipset that controls
the entire PC system.
Descriptions in this chapter will help you configure your system using the BIOS Setup screens.
Note: MultiTech has pre-set the BIOS before shipping the Gatekeeper. In most cases, the user will not need to change
any BIOS settings. However, if any hardware within the Gatekeeper has been changed, or if the boot sequence has been
changed, the user will need to revise the BIOS accordingly.

The base memory size and the extended memory size are displayed in the above table. This is
automatically read from your system. You do not need to set these parameters. The screen displays
the date and time, which the operator must set correctly after powering up the computer. The format
of the date/time display is as follows:
Date:
< Month >, < Date > and <Year >. Ranges for each value are on the CMOS Setup Screen, and the
week-day will be skipped automatically.
Time:
< Hour >, < Minute >, and < Second >. Use 24 hour clock format, i.e., for p.m. numbers, add 12 to
the hour. For example, 4:30 p.m. should be expressed as 16:30:00.

Appendix C - SBC Configuration Details
Drives: Primary Master/Slave & Secondary Master/Slave
In general, the SBC can handle four disk drives: a primary master, a primary slave, a secondary
master, and a secondary slave. The hard drive shipped with the Gatekeeper is a Primary Master drive
designated as Drive C. An IDE CDROM is supplied and functions as a Primary Slave drive and is
designated as Drive D. The type and mode settings for the primary master and the primary slave
drives should, in most cases, be AUTO.
When this field of the Standard CMOS Setup screen is set to AUTO, the SBC will automatically detect
the hard drive(s) in the system. The SBC can auto-detect 45 specific drive types (designated 1-45 in
this field).
The drive type can also be entered manually. If entered manually, the drive in use must match the type
entered in this field. If the drive being used is not of the type specified in this field, it will not work
properly in the Gatekeeper. For drives not on the list of 45 types, a user-defined drive can also be
specified in this field (as type User). When User is selected for this field, the operator needs to
specify the parameters of the hard drive (number of cylinders, heads, etc.). This information should be
provided in the documentation for the hard drive unit (this information is often specified on the exterior
of the hard drive unit, as well).
Note: If your SBC has trouble detecting your hard drive when the Type field in the Standard CMOS Setup screen is set
to AUTO, then you should enable the IDE HDD Auto Detection function in the CMOS Setup Utility screen. If the hard
drive is still not detected, designate the Type as User and enter the hard-drive values into the Standard CMOS Setup
screen
If the controller of the hard-disk drive interface is ESDI, the selection shall be Type 1.
If the controller of the hard-disk drive interface is SCSI, the selection shall be None
If the controller of the hard-disk drive interface is CD-ROM, the selection shall be None
Type:
Describes the hard drive. Default value is AUTO. Other values: 1-45, user, and none.
CYLS.:
Denotes the number of cylinders in the specified drive type.
HEADS:
Denotes the number of heads in the specified drive type.
PRECOM:
Precom is the read delay circuitry which takes into account the timing differences between the inner
and outer edges of the surface of the disk platter. This number designates the starting cylinder of the
signal.
LZONE:
Lzone is the landing zone of the heads. This number determines the cylinder location where the heads
will normally park when the system is shut down.
SECTORS:
Denotes the number of sectors in the specified drive type.
Size (Capacity):
Denotes the formatted capacity of the drive based on the following formula: (# of heads) X (# of
cylinders) X (# of sectors) X ( 512bytes/sectors)
Drive A and Drive B:
The options are 360 KB 5.25in, 1.2 KB 5.25in, 720 KB 3.5in, 1.44 MB 3.5in, 2.88 MB 3.5in and None. Not
Installed could be used as an option for workstations without disk drives.

The parameters accessible on this screen govern the systems default speed, boot-up sequence,
keyboard operation, shadowing, and security.
Note: MultiTech presets all BIOS features before shipping the Gatekeeper. BIOS features should not be changed except
by expert operators.
Virus Warning
When this item is enabled, the Award BIOS will monitor the boot sector and partition table of the hard
disk drive for any attempt at modification. If an attempt is made, the BIOS will halt the system and the
following error message will appear.
! WARNING !
Disk boot sector is to be modified
Type Y to accept write or N to abort write
Award Software, Inc.
Afterwards, if necessary, you will be able to run an anti-virus program to locate and remove the
problem before any damage is done.
Enabled: Activates automatically when the system boots up. Causes a warning message to appear
when anything attempts to access the boot sector or hard disk partition table.
Disabled: No warning message will appear when anything attempts to access the boot sector or hard
disk partition table. (Default.)
NOTE: Many disk diagnostic programs which attempt to access the boot sector table can cause the above warning
message. If you will be running such a program, we recommend that you disable Virus Protection beforehand. When
enabled, this feature can cause problems when installing Windows 95.
CPU Internal Cache/External Cache
These two settings affect memory access speed, generally increasing access speed when enabled. The
default value is Enabled.
Enabled: Enable cache
Disabled: Disable cache
Quick Power On Self Test
This setting affects the duration of the Power On Self Test (POST), which occurs after you power up
the computer. If enabled, the BIOS will shorten or skip some check items during the POST.
Enabled: Enable quick POST (Default)
Disabled: Normal POST
Boot Sequence
This setting determines which drive to search first for booting files at startup. The default value is C, A.
C, A System will first search for a hard disk then a floppy disk drive.
A, C System will first search for a floppy disk drive, then for a hard drive.
Boot Up Floppy Seek
During POST, BIOS will determine if the floppy disk drive installed has 40 or 80 tracks. 360K type has
40 tracks while 760K, 1.2M and 1.44M are all 80-track devices.
Enabled: BIOS searches for the floppy disk drive to determine if it is 40 or 80 tracks. Note that BIOS
cannot tell from 720K, 1.2M or 1.44M drive type as they are all 80 tracks (Default).
Disabled: BIOS will not search for the type of floppy disk drive by track number. Note that there will
not be any warning message if the drive installed is 360K.
MultiVOIP Gatekeeper User Guide 71
Page 71
Boot Up NumLock Status
This enables you to determine the default state of the numeric keypad. By default, the system boots up
with NumLock on.
On Keypads number keys are active.
Off Keypads arrow keys are active.
Boot Up System Speed
Selects the default system speed the normal operating speed at power up.
High Sets the speed to high (default)
Low Sets the speed to low
Regardless of which setting is chosen, the operator can still use the turbo switch to toggle between
High and Low modes during operation.
Gate A20 Option
This entry enables you to select how gate A20 is handled. Gate A20 is a device used to address
memory above 1 Mbyte. Initially, Gate A20 was handled by a pin on the keyboard. Today, while
keyboards still provide this support, it is more common, and much faster, for the system chipset to
provide support for gate A20.
Normal keyboard (default)
Fast chipset
Typematic Rate Setting
Enable the typematic function if you want to be able to configure the key-repetition characteristics of
your keyboard. When typematic is disabled, continually holding down a key on your keyboard will
generate only one instance. In other words, the BIOS will only report that the key is down. When the
typematic rate is enabled, the BIOS will report as before, but it will then wait a moment, and, if the key
is still down, it will begin the report that the key has been depressed repeatedly. For example, you
would use such a feature to accelerate cursor movements with the arrow keys.
Enabled Enable typematic rate
Disabled Disable typematic rate (default)
Typematic Rate (Chars/Sec)
When the typematic rate is enabled, the typematic rate selection enables you select the rate at which
a held-down key will produce acceleration. Acceleration refers to multiple instances of a
character (letter, number, or symbol) or other multiple keyboard effects (like cursor movement with
arrow keys and character removal with the Delete keys).
6 6 characters per second (default)
8 8 characters per second
10 10 characters per second
12 12 characters per second
15 15 characters per second
20 20 characters per second
24 24 characters per second
72 MultiVOIP Gatekeeper User Guide
Page 72
30 30 characters per second
Typematic Delay (Msec)
When the typematic rate is enabled, this selection enables you to select the delay between when the
key is first depressed and when the acceleration begins.
250 250 msec (default)
500 500 msec
750 750 msec
1000 1000 msec
Security Option
Enables you to limit access to the computer system or to the BIOS Setup menus. When System security
is enabled, the system will not boot and access to Setup will be denied if the correct password is not
entered at the prompt. When Setup security is enabled, the system will boot, but access to Setup will
be denied if the correct password is not entered at the prompt.
System security boot & BIOS access require password
Setup security BIOS access requires password (default)
Appendix C - SBC Configuration Details
No security password not required
Note: To disable security, select PASSWORD SETTING at the CMOS Setup Utility menu. You will be asked to enter a
password. Do not type anything; just press Enter, and security will be disabled. Once its disabled, the system will boot
and you can enter Setup freely.
Video BIOS Shadow
Determines whether the video BIOS will be copied to RAM. However, it is optional depending on chipset
design. Video Shadow will increase the video speed.
Enabled Video shadow is enabled (default)
Disabled Video shadow is disabled
C8000 - CFFFF Shadow/DC000 - DFFFF Shadow
Determines whether option ROMs will be copied to RAM or not. An example of such option ROM would
be support of on-board SCSI hard-drive functionality.
Enabled Optional shadow is enabled
Disabled Optional shadow is disabled (Default)
Chipset Features Setup
This menu lets you 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.
However, these parameters should never need to be altered. The default settings have been chosen
because they provide the best operating conditions for your system. The only time you might consider
making any changes would be if you discovered that data was being lost while using your system.
If you choose CHIPSET FEATURES SETUP from the CMOS Setup Utilities menu, the following screen appears.
MultiVOIP Gatekeeper User Guide 73
Page 73
Figure C-7. Chipset Features Setup
By moving cursor to the desired field and pressing < F1 > key, all values for that field will be displayed.
Auto Configuration Function:
When this option is Enabled, the BIOS automatically configures cache and clock settings based on
detection of the CPU clock speed. The user cannot change the other parameters. Set this option to
Disabled to do manual setting of DRAM , cache, and I/O bus clock operating parameters. Enabled
is the default.
DRAM 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. One data-loss
scenario that relates to DRAM timing values occurs when the computer contains mixed-speed DRAM
chips; greater delays may be required to preserve the integrity of the data held in the slower memory
chips and, consequently, data may be lost.

8 Bit I/O Recovery Time
74 MultiVOIP Gatekeeper User Guide
Page 74
The recovery time is the length of time, measured in CPU clock periods, that the system will delay after
completing an input/output request. This delay occurs because the CPU operates much faster than the
input/output bus and, therefore, the CPU must be delayed to allow for the completion of the I/O.
This setting determines the recovery time allowed for 8 bit I/O. Choices are from 1 to 8 CPU clock
periods.
3 clock periods is the default setting.
16 Bit I/O Recovery Time
This setting determines the recovery time allowed for 16 bit I/O. Choices are from 1 to 4 CPU clock
periods.
2 clock periods is the default setting.
Memory Hole At 15M-16M
In order to improve performance, certain space in memory can be reserved for ISA cards. This
memory must be mapped into the memory space below 16 MB.
Enabled memory hole supported

PM Control APM
When enabled ( YES ), an Advanced Power Management device will be activated to enhance the
Maximum Power Saving mode and to stop the CPU internal clock. The Advanced Power Management
function operates only if Maximum Power Saving is enabled. When enabled ( YES ), the system BIOS
will wait for APMs prompt before it enters any PM mode (Doze, Standby or Suspend). If APM is
installed, and if a task is running and the timer has timed out, APM will not prompt the BIOS to employ
any power saving mode.
Video Off Method
This determines how the monitor is blanked (V/H SYNC+Blank). This selection will cause the system
to turn off the vertical and horizontal synchronization ports and write blanks to the video buffer (Blank
Screen). This option only writes blanks to the video buffer.

Note: Doze, Standby, and Suspend are configurable only when User Defined power management has been selected.
Doze Mode
This timeout setting determines how long the PC must be idle before entering Doze mode. Values
range from 10 seconds to 2 hours. Doze mode can also be disabled. In Doze mode, the CPU clock runs
at a slower speed while all other devices continue operating at full speed.
Standby Mode
This timeout setting determines how long the PC must be idle before entering Standby mode. Values
range from 30 seconds to 2 hours. Standby can also be disabled. When Standby mode is engaged, the
PCs hard drive and its video are turned off while all other devices continue operating at full speed.
Suspend Mode
This timeout setting determines how long the PC must be idle before entering Suspend mode. Values
range from 30 seconds to 2 hours. Suspend can also be disabled. In Suspend mode, all devices except
the CPU are shut off.
HDD Power Down
This timeout setting determines how long the PC must be idle before entering HDD Power Down mode.
In HDD Power Down mode, the hard disk drive will be shut off but all other devices remain active.

This enables you to configure your system to the type of IDE disk controller in use, ISA or PCI (default
value is PCI Auto). PCI Auto enables the system to determine automatically how your IDE disk system is
configured. Remember that this setting refers to the hard disk drive itself, rather than individual
partitions. Since each IDE controller supports two separate hard drives, you can select the interrupt
number (the INT#; the possible values are A, B, C, or D) for each. Note that the primary drive always
has a lower interrupt than the secondary drive.

clear any previously entered password from CMOS memory. You will be asked to confirm the
password. Type the password again and press Enter. You may also press Esc to abort the selection
and not enter a password.
Caution: Losing or forgetting your system password will render your computer unusable. Assign a password only if it is
necessary for security purposes. Restoring access after loss of a password is nontrivial and requires the clearing and reloading of BIOS settings. If a password is forgotten or lost, contact MultiTech Technical Support to establish a new
password.
To disable a password, just press Enter when you are prompted to enter the password. A message
will confirm that the password is to be disabled. Once the password has been disabled, the system will
boot and you can enter Setup freely.
Password Disabled
When a password has been enabled, you will be prompted to enter it every time you try to enter Setup.
This prevents an unauthorized person 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 would prevent unauthorized use of your computer.

Generally speaking, hard disk drives are categorized by size as follows:
Normal: HDD Size < 528MB
LBA: 528MB< HDD Size < 8.4 GB
Large: HDD Size > 8.4GB
If you specify a sub-standard mode for a hard disk drive when formatting, part of the drive will remain
unformatted and therefore inaccessible. For example, if you format a 4GB hard disk drive as a Normal
drive, only 528MB would be formatted and nearly 3.5GB would be unusable.
Auto Detection
The BIOS Setup will display all the possible modes that are supported by the HDD including NORMAL,
LBA, & LARGE. The user can select the appropriate mode.
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, and 63.
x no. Cylinder (1024)
x no. Head ( 16)
MultiVOIP Gatekeeper User Guide 79
Page 79
x no. Sector ( 63)
x no. Bytes per Sector ( 512)
Total: 528 megabytes
If the user sets the 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:
This new HDD accessing method overcomes the 528 megabyte bottleneck. The number of cylinders,
heads and 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 the sector,
head, and cylinder numbers into its own physical address inside the HDD.
The maximum HDD size supported by LBA mode is 8.4 gigabytes, which is obtained by the following
formula:
x no. Cylinder (1024)
x no. Head ( 255)
x no. Sector ( 63)
x no. of Bytes per Sector ( 512)
Total: 8.4 gigabytes
LARGE mode:
Some IDE HDDs contain more than 1024 cylinder without LBA support (in some cases, users 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
The BIOS tricks DOS (or other OS) that the number of cylinders 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.
Maximum HDD size in Large Mode:
x no. Cylinder (1024)
x no. Head ( 32)
x no. Sector ( 63)
x no. Per sector ( 512)
-
Total: 1 gigabyte
Note: Support of the LBA or LARGE mode of HDDs, requires some special software. All such software packages are
located in the Award HDD Service Routine (INT 13h). If the PC is running under a Operating System that replaces the
whole INT 13h, that PC may fail to access a HDD set to LBA or LARGE mode.

Canadian Limitations Notice
Notice: The ringer equivalence number (REN) assigned to each terminal device provides an indication
of the maximum number of terminals allowed to be connected to a telephone interface. The
termination of a interface can consist of any combination of devices subject only to the requirement
that the sum of the ringer equivalence numbers of all the devices does not exceed 5.
Notice: The Industry Canada label identifies certificated equipment. This certification means that the
equipment meets certain telecommunications network protective, operational and safety requirements.
The Industry Canada does not guarantee the equipment will operate to the users satisfaction.
Before installing this equipment, users should ensure that it is permissible to be connected to the
facilities of the local telecommunications company. The equipment must also be installed using an
acceptable method of connection. The customer should be aware that compliance with the above
conditions may not prevent degradation of service in some situations.
MultiVOIP Gatekeeper User Guide 83
Page 83
Repairs to certified equipment should be made by an authorized Canadian maintenance facility
designated by the supplier. Any repairs or alterations made by the user to this equipment, or
equipment malfunctions, may give the telecommunications company cause to request the user to
disconnect the equipment.
Users should ensure for their own protection that the electrical ground connections of the power utility,
telephone lines and internal metallic water pipe system, if present, are connected together. This
precaution may be particularly important in rural areas.
Caution: Users should not attempt to make such connections themselves, but should contact the
appropriate electric inspection authority, or electrician, as appropriate.
Compliance with BABT Requirements
Approved for connection to telecommunications system specified in the instructions for use subject to the
conditions set out in them.
Warning: Interconnection directly, or by way of other apparatus, of ports marked "SAFETY WARNING see
instructions for use" with ports marked or not so marked may produce hazardous conditions on the
network. Advice should be obtained from a competent engineer before such a connection is made.
It is a condition of approval that the power required by the host and the total of all adapter cards installed
within the host environment, together with any auxiliary apparatus, does not exceed the power
specification as stated in the Technical Reference Material of the host apparatus.
The power requirements for the MULTIMODEMISI are:
Modem operating voltages: +12V D.C., -12V D. C., +5V D.C.
Modem Power Consumption: 8 Watts
In order to maintain the independent approval of this card, it is essential that when other option cards are
introduced which use or generate a hazardous voltage, the minimum creepages and clearances specified in
the following table are maintained. A hazardous voltage is one which exceeds 42.4V peak a.c or 50V d.c. If
you have any doubt, seek advice from a competent engineer before installing other adapters into the host
equipment.
The equipment must be installed such that with the exception of connection to the host, clearance and
creepage distances shown in the following table are maintained between the card and any other
assemblies which use or generate a voltage shown in that table. The larger the distance shown in brackets
applies where the local environment within the host is subject to conductive pollution or dry
nonconductive pollution which could become conductive due to condensation. Failure to maintain these
minimum distances would invalidate approval.
