2-3 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

12 CommPlete 4000 Server SBC, Model IPC-551

Hardware Configuration

active value for user-changeable 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

Jumper Settings

The IPC-551 comes equipped with one of five CPUs of differing
operating speeds: 233 MHz, 266 MHz, 300 MHz, 333 MHz, or 366 MHz.

Award BIOS Setup

Chapter 5

Award BIOS Setup

5.1 Introduction

This chapter describes the function of the BIOS in managing the
features of your system and 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 computers hardware. As the
interface between the hardware and the operating system, the BIOS
enables you to make basic changes to your systems hardware without
having to write a new operating system.

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

CommPlete Series 4000 Server SBC, Model IPC-551 41

Award BIOS Setup

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 non­standard, 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 CommPlete

4000. In most cases, the user will not need to change any BIOS settings.
However, if any hardware within the CommPlete 4000 has been changed,
or if the boot sequence has been changed, the user will need to revise the
BIOS accordingly.

5-2 Entering Setup

To enter the BIOS Setup screen, power on the computer and then
press the Delete key immediately. The other way to enter Setup is to
power on the computer and then, when the below message appears
briefly at Phe bottom of the screen during the POST (Power On Self
Test), press the Delete key or simultaneously press <Ctrl>, < Alt >,
and < Esc > keys (Control, Alternate, & Escape).

TO ENTER SETUP BEFORE BOOT PRESS <CTRL-ALT-ESC> OR

<DEL> KEY

As long as the above message is present on the screen you may press
the <Del> key (the one that shares the decimal point at bottom of the
number keypad) to access the Setup program. After a moment, the
main menu of the Award SETUP program will appear on the screen:

for p.m. numbers, add 12 to the hour. For example, 4: 30 p.m. should
be expressed as 16:30:00.

Drives: Primary Master/Slave & Secondary Master/Slave

In general, the IPC-551 can handle four disk drives: a primary master, a
primary slave, a secondary master, and a secondary slave. The hard
drive shipped with the CommPlete 4000 will be a Primary Master
drive designated as Drive C. An IDE CDROM may optionally function

CommPlete Series 4000 Server SBC, Model IPC-551 45

Award BIOS Setup

as a Primary Slave drive and be designated as Drive D. The type
and mode settings for the primary master and the primary slave
drives should, in most cases, be AUTO. The default configuration
state for the secondary master/slave is DISABLED.

When this field of the Standard CMOS Setup screen is set to AUTO,
the IPC-551 will automatically detect the hard drive(s) in the system.
The IPC-551 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 CommPlete 4000. For drives not on the list of 45 types, a user­defined drive can also be specified in this field (as type User).
When User is selected for this field, the operator must 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 IPC-551 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

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.

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.

5-5 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

Award BIOS Setup

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 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.

ISA Clock:

Defines the clock value for the ISA bus. Usually, the ISA bus clock
should be programmed to 8Mhz. For example, when the PCI clock is
33MHz, choose PCICLK/4. PCICLK/4 is the default value.

Cache Features

System BIOS Cacheable

When enabled, accesses to the system BIOS ROM addressed at F0000H­FFFFFH are cached.

Enabled BIOS access cached

Disabled BIOS access not cached

Disabled is the default.

CommPlete Series 4000 Server SBC, Model IPC-551 57

Award BIOS Setup

Video BIOS Cacheable

As with caching the System BIOS above, enabling the Video BIOS cache
will cause access to video BIOS addressed at C0000H to C7FFFH to be
cached.

Enabled Video BIOS access cached

Disabled Video BIOS access not cached

Disabled is the default.

PCI and IDE Configuration

8 Bit I/O Recovery Time

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

Disabled memory hole not supported (default)

disabled, each of the ranges are from 1 min. to 1 hr. except for HDD
Power Down which ranges from 1 min. to 15 min. (HDD can also be
disabled).

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 APMs 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
PCs 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.

Award BIOS Setup

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 re-loading 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.

You determine when the password is required within the BIOS
Features Setup menu and its Security option (presented earlier). If the
Security option is set to System, the password will be required both
at boot and at entry to Setup. If set to Setup, prompting only occurs
when trying to enter Setup.

mode are 1024, 16, and 63.

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:

no. Cylinder (1024)

x no. Head ( 255)

x no. Sector ( 63)

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.

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:

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.

Appendix C: Troubleshooting

Appendix C:

Troubleshooting

C-1 Introduction

This appendix outlines errors that may occur during system operation
and likely remedies for these problems.

C-2 Troubleshooting with Error Messages

This section describes error messages and their use in
troubleshooting. Since many errors can be caused by poor cable
connections, you should verify that all cables have been connected
firmly to their proper receptacles. If error messages persist after the
recommended adjustments have been made, contact MultiTech
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. The battery is located inside the real-time clock chip.
Replacement requires soldering. The user should return the IPC-551 to
MultiTech Systems for repair if the clock fails.

CMOS Checksum Error: This error indicates that the CMOS has
been corrupted. Corruption may be caused by a weak battery.

Display Switch Is Set Incorrectly: The display switch on the
motherboard can be set to either monochrome or color. This error

CommPlete 4000 Server SBC, Model IPC-551 79

Appendix B: Technical Summary

message indicates that the switch setting does not match the video
display mode specified in the Setup screen. Determine which setting is
correct. Then either turn off the system and change the jumper, or
enter Setup and change the entry in the Video field.

Disk Boot Failure: When you cant 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
disk drive has been formatted correctly. Then reboot the system.

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 disk 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.

80 CommPlete 4000 Server SBC, Model IPC-551

Appendix C: Troubleshooting

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 Size Has Changed: Memory has been added or removed
since the last boot. In EISA mode, use the Configuration Utility to re­configure memory. In ISA mode, enter the BIOS Setup screen and type
the new memory size in the memory field.

Memory Verifying Error : It indicates an error verifying a value
already written to memory. Use the specified memory location and
your systems memory map to locate the bad chip.

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.
