4 BIOS Setup Utility

CommPlete Communications Server 17

RAS96 RASCard User Guide

Introduction

This chapter describes the Award Setup utility, which is built into the RASCard’s
BIOS. The Setup utility allows users to modify the basic system configuration. This
special information is then stored in battery-backed CMOS RAM that retains the setup
information when the power is turned off.

The Award BIOS installed in your computer system’s read-only memory (ROM) is a
custom version of the standard Award BIOS. This means that it supports Intel Pentium
processors in a standard ISA/PCI 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 special support for fine-tuning the
430FX Triton chipset that controls the system.

Starting Setup

When you turn on the RASCard, the BIOS reads the system information contained in
the CMOS and begins the process of checking out and configuring the system. When it
finishes, the BIOS looks for an operating system on the hard disk, then launches and
turns control over to the operating system.

To run Setup, press the DELETE key when the following message appears during the
power-on self-test (POST).

TO ENTER SETUP BEFORE BOOT PRESS DEL KEY

If the message disappears before you respond, and you still wish to enter Setup, restart
the system to try again by turning it off and on or pressing the recessed reset button on
the front panel. If you do not press the key at the correct time and the system does not
boot, an error message will be displayed and you will be asked to...

In Case of Problems

The Award BIOS supports an override that loads default CMOS settings, should you
discover that your RASCard is no longer able to boot after you change Setup.

SHIFT+F2 to select the previous color.

You can restart by using the power switch, the reset button, or by pressing CTRL, ALT,
and DELETE at the same time.

Only change settings that you thoroughly understand. To this end, we strongly
recommend that you avoid making any changes to the chipset defaults. These defaults
have been carefully chosen by both Award and your systems manufacturer to provide
the absolute maximum performance and reliability. Even a seemingly small change to
the chipset setup may require you to use the override.

Memory

The category is display-only. Values are determined by the BIOS power-on self-test
(POST).

Base
Memory

Extended
Memory

Expanded
Memory

The POST determines the amount of base (or conventional) memory
installed in the system. The value of the base memory is typically 640K
for systems with 640K or more memory installed on the motherboard.

The BIOS determines how much extended memory is present during the
POST. This is the amount of memory located above 1MB in the CPU’s
memory address map.

Expanded Memory is memory defined by the Lotus/Intel/Microsoft
(LIM) standard as Expanded Memory Specification (EMS). While most
standard DOS applications cannot access memory above 640K, EMS
provides an interface allowing access to all system memory. Though still
in use by some DOS applications, EMS is rapidly declining in
importance, since new processors and operating systems prefer
extended memory. A special, expanded memory device driver is
required to use memory as Expanded Memory.

Other
Memory

26 CommPlete Communications Server

This refers to the memory located in the 640K to 1024K address space.
This is memory that can be used for different applications. DOS uses
this area to load device drivers in an effort to keep as much base memory
free for application programs. The BIOS is the most frequent user of this
RAM area, since this is where it shadows RAM.

BIOS Features Setup

Gate A20 Option

This entry allows you to select how the gate A20 is handled. The gate A20 is a device
used to address memory above 1 MB. Initially, the gate A20 was handled via a pin on
the keyboard. Today, though keyboards still provide this support, it is more common,
and much faster, for the system chipset to provide support for gate A20.

Normal Keyboard.
Fast Chipset (Default).

Memory Parity Check

Parity is a method of checking for errors in system memory. There are both parity and
non-parity memory types. At boot, the Award BIOS both sizes and tests all memory.
Normally, when a parity error is detected, the BIOS will display a message describing
the problem as well as the problem’s location, if possible. The boot process will then
terminate and you will not be able to continue until the bad SIMM is located and
replaced.

Disabling the Memory Parity Check allows the system to bypass the test and allow
your system to boot. You then have a choice of continuing to operate your system or
attempting to remedy the problem.

Enabled Normal memory parity check (Default).
Disabled Ignore memory parity check.

Typematic Rate Setting

This determines if the typematic rate is to be used. When it is disabled, continually
holding down a key on your keyboard will generate only one character. 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 to 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.

Chipset Features Setup

This section allows you to configure the system based on the specific features of the
installed chipset. The chipset manages bus speeds and access to system memory
resources, such as DRAM and the L2 external cache. It also coordinates
communications between the conventional ISA bus and the PCI bus. These items
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.

4 BIOS Setup Utility

DRAM Timing

The first chipset settings deal with CPU access to dynamic random access memory
(DRAM). The DRAM timing should match the speed of the slowest installed memory.
For instance, if 60 ns SIMMs are installed on the RASCard, you should set this item to
60 ns. But if you install both 60 ns and 70 ns SIMMs, you should change it to 70 ns.

System BIOS Cacheable

When this item is enabled, accesses to the system BIOS ROM addressed at F0000H­FFFFFH are cached, provided that the cache controller is enabled.

Enabled BIOS access cached.
Disabled BIOS access not cached (Default).

CommPlete Communications Server 31

RAS96 RASCard User Guide

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, if the cache
controller is also enabled.

Enabled Video BIOS access cached.
Disabled Video BIOS access not cached (Default).

8-Bit I/O Recovery Time

The recovery time is the length of time, measured in CPU clocks, which the system will
delay after the completion of an input/output (I/O) request. This delay takes place
because the CPU is operating so much faster than the I/O bus that the CPU must be
delayed to allow for the completion of the I/O.

This item allows you to determine the recovery time allowed for 8-bit I/O. Choices are
from 1 through 8 CPU clocks. The default is 1 clock.

16-Bit I/O Recovery Time

This item allows you to determine the recovery time allowed for 16 bit I/O. Choices are
from 1 through 4 CPU clocks. The default is 1 clock.

Memory Hole At 15M-16M

In order to improve performance, certain memory space 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).

IDE HDD Block Mode

This allows your hard disk controller to use the fast block mode to transfer data to and
from your hard disk drive (HDD).

Enabled IDE controller uses block mode (Default).
Disabled IDE controller uses standard mode.

IDE Primary Master PIO / IDE Primary Slave PIO

IDE hard disk controllers can support two separate hard disks. These drives have a
master/slave relationship which are determined by jumpers on the hard disk drives.
Your system supports one IDE controller, so you have the ability to install up to two
separate hard disks. The secondary IDE controller has been disabled.

PIO means Programmed Input/Output. Rather than have the BIOS issue a series of
commands to effect a transfer to or from the disk drive, PIO allows the BIOS to tell the
controller what it wants and then let the controller and the CPU perform the complete
task by themselves. This is simpler, more efficient, and faster.

Your system supports five modes, numbered from 0 (default) through 4, which differ
primarily in timing. When Auto is selected, the BIOS will select the best available mode.

PCI Concurrancy

PCI concurrency means that more than one PCI device can be active at a time.

Enabled Multiple PCI devices can be active (Default).
Disabled Only one PCI device can be active at a time.

PCI Streaming

Data is typically moved to and from memory and between devices in discrete chunks of
limited sizes. This is because the CPU is being used in the exchange. On the PCI bus,
data can be streamed, that is, much larger chunks can be moved without the use or
intervention of the CPU.

Enabled Streaming allowed on the PCI bus (Default).
Disabled Streaming off for the PCI bus.

PCI Bursting

The PCI bus supports a mode by which large amounts of data is moved in short intense

Power Down Activities

Power Down Activities events are I/O events whose occurrence can prevent the system
from entering a power saving mode or can awaken the system from such a mode. In
effect, the system remains alert for anything that occurs to a device that is configured as
ON, even when the system is in a power down mode.

COM Ports Accessed

When set to ON (default), any event occurring at a COM (serial) port awakens a system
that has been powered down. This includes mouse activity if a mouse is connected to
COM1.

LPT Ports Accessed

When set to ON (default), any event occurring at an LPT (printer) port awakens a
system that has been powered down.

Drive Ports Accessed

When set to ON (default), any event occurring at a hard or floppy drive port awakens a
system that has been powered down.

IRQs

The following interrupt requests (IRQs) can be used to waken a system much as the
COM ports and LPT ports can. When an I/O device wants to gain the attention of the
operating system, it signals this by causing an IRQ to occur. When the operating
system is ready to respond to the request, it interrupts itself and performs the service.

The choices are ON and OFF. OFF is the default. When an IRQ is set to ON, activity
will neither prevent the system from going into a power management mode nor
awaken it. IRQ8 (Real Time Clock Alarm) should always be set to OFF so that any
software alarm or event calendar can awaken the system.

IRQ3 (COM 2) IRQ8 (RTC Alarm) IRQ13 (Coprocessor)
IRQ4 (COM 1) IRQ9 (IRQ2 Redir) IRQ14 (Hard Disk)
IRQ5 (LPT 2) IRQ10 (Reserved) IRQ15 (Reserved)

PCI Configuration Setup

This section describes how to configure the PCI bus system. The PCI bus allows I/O
devices to operate at speeds near the speed the CPU itself uses to communicate with its
own special components. It is strongly recommended that only experienced users
should make any changes to the default settings.

4 BIOS Setup Utility

Slot (x) Using INT#

Some PCI devices use interrupts to signal that they need to use the PCI bus. Some
devices, notably most graphics adapters, may not need an interrupt service at all. Each
PCI slot is capable of activating up to four interrupts, INT# A, INT# B, INT# C, and
INT# D.

INT# A Assign if the device in the slot requires one interrupt service.
INT# B Assign only if the device in the slot requires two interrupt services rather

than just one.

INT# C Assign only if the device in the slot requires three interrupt services.
INT# D Assign only if the device in the slot requires four interrupt services.
AUTO Allows the PCI controller to automatically allocate the interrupts (Default).

1st/2nd/3rd/4th Available IRQ

An INT# is an interrupt request that is signaled to and handled by the PCI bus.
However, since the operating system usually has the final responsibility for handling
I/O, an INT# can be mapped to an IRQ if the device occupying a given slot requires an
IRQ service. By default, IRQs 9 and 10 are mapped to PCI devices, but any unused IRQ
can be used.

CommPlete Communications Server 37

RAS96 RASCard User Guide

You can select which INT# is associated with each PCI slot and which conventional
IRQ is associated with one of the two available INT#s.

A setting of NA means the IRQ has been assigned to the ISA bus and is not available to
any PCI slot.

PCI IRQ Activated by

This item sets the method by which the PCI bus recognizes that an IRQ service is being
requested by a device. Under all circumstances, you should retain the default
configuration unless advised otherwise by Multi-Tech.

Choices are Level (default) and Edge.

PCI IDE IRQ Map to

This allows you to configure your system to the type of IDE disk controller in use. By
default, Setup assumes that your controller is an ISA (Industry Standard Architecture)
device rather than a PCI controller.

If you have equipped your system with a PCI controller, changing this allows you to
specify which slot has the controller and which PCI interrupt (A, B, C, or D) is
associated with the connected hard disks.

Remember that this setting refers to the hard disk drive itself, rather than individual
partitions. Since each IDE controller supports two separate hard disks, you can select
the INT# for each. Again, you will note that the primary has a lower interrupt than the
secondary as described in Slot x Using INT# above.

Selecting PCI-AUTO allows the system to automatically determine how your IDE disk
system is configured.

E1 Basics

E1 service provides a two-way digital telecommunications connection at 2.048M bps.
The local PTT (a country’s national Postal, Telephone and Telegraph agency) provides
the entire circuit within a country, and interconnects with one or more other circuits for
international network connections.

E1’s higher equipment and leased line costs are more than offset by its inherent
advantages: reduced phone bills (payback in months) , increased control of the
network, improved reliability, quick and cheap change implementation, vastly
increased speed and improved voice quality due to the nature of digital vs. analog
lines.

The CEPT E1 speed of 2.048M bps is derived from 30 channels at 64K bps each, plus
8K bps for synchronization. To be transmitted effectively, the normally incompatible
voice and data must be “mixed” for compatibility. When digitizing the analog voice
signal, there is a question of the number of bits that can be transmitted economically,
and how to best represent the “smooth variation” in loudness. “Best” typically implies
maximum voice quality, but there can also be tradeoffs for cost, circuit availability,
bandwidth, and reliability. The current world-wide standard for digital voice is PCM
(Pulse Coded Modulation). A “codec” (coder-decoder) selects the value closest to the
true analog signal, minimizing the distortion, and making the voice transmission
acceptable to the human ear. Technologies like aliasing (voice signal filtering) and non­linear sampling are used to overcome problems in performing PCM voice compression.
The method of non-linear sampling used in Europe, Mexico and the U.K. is called A­law. Similar technology is used at the sending and receiving ends (i.e., analog-to­digital conversion at one end, and then digital-to-analog conversion at the other end).

The frequencies around 1000 Hz convey most of the information in a person’s voice.
Several methods of non-linear sampling are available, including Pulse Code Modula­tion (PCM), Differential PCM (DPCM), Adaptive DPCM (ADPCM), CVSD, VQC, and
HCV. Each has its own associated data transfer rate, cost, and quality factors.

E1 Frame Formats

Framing is the way E1 equipment formats bits on the E1 line for encoding digital voice.
Selecting the method of framing is a major E1 network design issue. There are two
options for E1 frame formatting:

• CRC4 (16 Frame)

• FAS (2 Frame)

E1 Line Coding

Line coding is the method the E1 Daughter Card uses to maintain a sufficient density of
ones in the bit stream, which is required for clock synchronization. HDB3 is the line
coding method used for E1 transmission.

• AMI (Alternate Mark Inversion) inverts, or changes the polarity of, successive ones

(marks) to maintain ones density.

• HDB3 (High Density Bipolar Order 3) is transparent (not confused with data). It

relies on the transmission of both positive and negative pulses. It is based on AMI,
but extends this method by inserting violation codes whenever 4 or more 0s occur
consecutively. This and similar (more complex) codes have replaced AMI in modern
distribution networks.

5 E1 Daughter Card

Signaling Options

The signaling option defines how the E1 Daughter Card signals the telco switch when
starting (“seizing”) the phone line or trunk line.

• R2 Digital

• R2 MF
R2 MF signaling is used outside the United States, mostly in Europe and the Far East.

A sequence of tones initiated at the central office (PTT) is exchanged back and forth
between the PTT and the subscriber, generally at an R2 MF of 4 to 4.5 tones per second.
Although this tone rate work successfully in most instances, some countries require
tone exchange rates of up to 8 transactions per second. If the central office sends a tone
and is not answered fast enough with a return tone, the call is terminated. The delay
introduced by asking the application for each new tone limits the rate of signaling.

DNIS digits

The DNIS (Dialed Number Identification Service) digits option describes the number of
DNIS digits to be received from the CO. For example, when you dial a number, you
generally dial seven digits. Therefore, seven is the number of DNIS digits you would
receive from the switch. In general, this option should be left at the default value of 0 to
use automatic mode. You need to enter a DNIS digits value only if your telco switch
does not support automatic mode.

PCB Description

The E1 Daughter Card has two external jacks: an RJ-48 E1 line jack, and an E1 line
monitoring Bantam jack. Connection to the RAS96 RASCard is via two 32-pin headers
(J3 and J4 in Figure 4).

RJ-11 Alarm Jack

The RJ-11 Alarm jack, located on the RASCard, is for connection to an external alarm
system, such as a relay, warning light or bell. It contains two wire pairs: one normally
closed pair, pins 4 and 6, that opens in an alarm condition, and one normally open
pair, pins 5 and 6, that closes in an alarm condition. If an error condition occurs,
contact your local service provider.

E1 Line Monitoring Jack

The E1 Line Monitoring jack is for phone company testing purposes, and should only
be used by a telco service representative using telco test equipment.

Test Modes

E1 Daughter Card test modes are controlled by the MultiCommManager software; refer
to the MultiCommManager User Guide for more information.

6 Solving Problems

CommPlete Communications Server 55

RAS96 RASCard User Guide

Introduction

This chapter describes steps you can take in the event of a RASCard failure. As with
any microcomputer product, start with simple hardware and software tests, and work
toward more complex tests or operating system/application software tests.

Be sure to check the cable connections to the RASCard. Also, check the Setup utility
configuration settings for your particular site (Chapter 4).

Troubleshooting

The following troubleshooting procedures address typical problems and recommend
some basic solutions. If a problem arises while you are in an application, refer to the
software documentation.

The RASCard has no video

• Verify that the monitor is plugged in and turned on, and that video cable is
connected to the video connector on the RASCard.

• Verify that the RASCard is turned on.

• Verify that system power is on.

• Verify that the RASCard is seated properly in its slot. Note: Make sure to turn power
off before reseating cards.

• Verify that the memory SIMMs are seated properly on the RASCard. If two or four
SIMMs are installed, they must be the same brand, size and speed. Fill Bank 1 first.

• Remove any other device cards from the segment and turn on the RASCard. If the
RASCard has video now, then there is a conflict with one of the device cards. Check
the configuration of each device card.

• Remove all connectors from the RASCard except the video connector, then turn on
the RASCard. If the RASCard 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.

• Try the RASCard in a different segment (if CC9600) or CommPlete chassis. If this
works, there is a problem with the segment or chassis previously used.

• If the problem persists, contact Multi- Tech’s Technical Support Department.

The RASCard does not boot correctly, or hangs after the video appears

• Run the BIOS Setup utility to verify that you have the correct configuration for the
system and drives (press DEL as system boots).

• Verify that the RASCard and device cards are seated properly in the CC9600
chassis. Note: Make sure to turn power off before reseating cards.

• Verify that the fan on the CPU heat sink is working. The CPU may be overheating.

CommPlete Communications Server56

• The hard disk or floppy drive cables are not connected properly, or their parameters
are not set properly in Setup.

• Verify that enough memory is installed to load the intended applications.

• Verify that the memory SIMMs are seated properly on the RASCard. If two or four
SIMMs are installed, they must be the same brand, size and speed. Fill Bank 1 first.

• If the problem persists, contact Multi- Tech’s Technical Support Department.

The COM1 port does not respond correctly

• Check the Setup configuration to verify that the ports are enabled.

• Check that cables are connected properly and peripherals are turned on and
configured properly.

• If the problem persists, contact Multi- Tech’s Technical Support Department.

The keyboard does not respond to key strokes

• Connect the keyboard cable to bottom round connector on the RASCard.

6 Solving Problems

• If a cable converter is used to connect a large 5-pin DIN connector to the small 6-PIN
PS/2 DIN connector on the RASCard, the converter could be bad or of the wrong
type.

• Verify that the keyboard works on a different system.

• If the problem persists, contact Multi- Tech’s Technical Support Department.

Invalid time, date or setup

• The battery is failing.

• The last system boot was incomplete. Verify in Setup that the configuration is
correct, and reboot the system.

• If the problem persists, contact Multi- Tech’s Technical Support Department.

Memory Upgrade

Two memory banks (Bank 1 and Bank 2) with two SIMM sockets per bank (M1 through
M4) are provided on the RASCard. The standard configuration has 16 MB of EDO
DRAM in Bank 1. The RASCard supports four 72-pin SIMMs of 4 MB, 8 MB, 16 MB, or
32 MB DRAM to form a memory size from 8 MB to 128 MB. The DRAM can be 60 ns or
70 ns, fast page mode or EDO, 32-bit non-parity or 36-bit parity. For a list of approved
SIMMs, see Appendix D.

Note: Each bank must have the same size memory installed in pairs. Always fill Bank 1
first.

2 × 32 MB 2 × 32 MB 128 MB

1. Turn the power off on the segment to be upgraded.

2. Remove the connectors on the back of the RASCard and loosen the screws that

hold the RASCard in place.

3. Use the ejector lever to remove the RASCard from the CommPlete rack and set the

card flat on a table.

4. The standard configuration has two 8 MB EDO DRAM SIMMs in bank 1. If you

plan to leave this memory installed and add memory to Bank 2, jump to Step 8.

5. Remove the SIMMs in Bank 1 by bending the metal tab on each side of the SIMM

socket until the SIMM falls sideways.

6. Place the new SIMMs into Bank 1 starting with the SIMM socket farthest from the

board edge. Notice that each SIMM has a notch cut out on one edge next to the
gold fingers. Place the SIMM into the SIMM socket so the notch in the SIMM is on
the side closest to the front bracket of the RASCard. The SIMM will go into the
socket at a 45 degree angle. Once the gold fingers of the SIMM are inside the pin

CommPlete Communications Server58

6 Solving Problems

contacts of the sockets, use your fingers to bend the SIMM upright until it is held
in place by the metal tabs.

7. Follow the same process for the second SIMM in Bank 1.

8. Select the memory SIMMs for Bank 2 and follow the same procedure as in Step 6.

Note: The front bracket of the RASCard may have to be removed to install SIMM 2
of Bank 2. When finished, replace the bracket.

9. Install the RASCard into the proper segment on the CommPlete and reconnect all

cables.

10. Power-up the segment and verify that the memory count displayed is correct.

11. If the RASCard does not see the proper amount of memory, verify that the SIMMs

are seated properly and call Multi- Tech’s Technical Support.Department. If you
wish to upgrade the memory and use the two SIMMs that came with the RASCard
you have three options:

a) Replace two 8 MB SIMMs in Bank 1 with two 4 MB SIMMs and add two 8

MB SIMMs to Bank 2 for 24 MB total.

b) Keep the 8 MB SIMMs in Bank 1 and add two 8 MB SIMMs to Bank 2 for 32

MB total.

c) Keep two 8 MB SIMMs in Bank 1 and add two 16 MB SIMMs to Bank 2 for 48

MB total.

Diagnostic Tests

The RASCard operates like a stand-alone PC, so it can run almost any off-the-shelf

diagnostic program. These programs are available at any software reseller and can

quickly help isolate component failures or adapter conflicts.

Calling Technical Support

For immediate help in finding and fixing RASCard problems, record the error

condition and call Multi- Tech’s Technical Support Department at [phone].

by two short beeps. This code indicates that a video error has occurred and that the
BIOS cannot initialize the video screen to display additional information.

Error Messages

B POST Messages

One or more of the following messages may be displayed if the BIOS detects an error
during the POST.

CMOS BATTERY HAS FAILED

CMOS battery is no longer functional. It should be replaced.

CMOS CHECKSUM ERROR

Checksum of CMOS is incorrect. This can indicate that CMOS has become corrupt. This
error may have been caused by a weak battery. Check the battery and replace if
necessary.

DISK BOOT FAILURE, INSERT SYSTEM DISK AND PRESS ENTER

No boot device was found. This could mean that either a boot drive was not detected or
the drive does not contain proper system boot files. Insert a system disk into Drive A:
and press ENTER. If the system should have booted from the hard disk, make sure that
the controller is inserted correctly and all cables are properly attached. Also, make sure
that the disk is formatted as a boot device. Then reboot the system.

DISKETTE DRIVES OR TYPES MISMATCH ERROR - RUN SETUP

The type of floppy drive installed in the system is different from the CMOS definition.
Run Setup to reconfigure the drive type correctly.

DISPLAY TYPE HAS CHANGED SINCE LAST BOOT

The display adapter has been changed since the system was last turned off. You must
configure the system for the new display type.

ERROR ENCOUNTERED INITIALIZING HARD DRIVE

The hard disk cannot be initialized. Make sure the adapter is installed correctly and all
cables are correctly and firmly attached. Also, make sure the correct hard disk type is
selected in Setup.

ERROR INITIALIZING HARD DISK CONTROLLER

Cannot initialize controller. Make sure that the correct hard disk type is selected in
Setup. Also check to see if a jumper needs to be set correctly on the hard disk.

FLOPPY DISK CNTRLR ERROR OR NO CNTRLR PRESENT

Cannot find or initialize the floppy drive controller. If there are no floppy drives
installed, be sure the Diskette Drive selection in Setup is set to NONE.

KEYBOARD ERROR OR NO KEYBOARD PRESENT

Cannot initialize the keyboard. Make sure the keyboard is attached correctly, and no
keys are being pressed during the boot.

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 at ...

Indicates a memory address error at a specific location. You can use this location along
with the memory map for your system to find and replace the bad memory chips.

Memory parity Error at ...

Indicates a memory parity error at a specific location. You can use this location along
with the memory map for your system to find and replace the bad memory chips.

MEMORY SIZE HAS CHANGED SINCE LAST BOOT

Memory has been added or removed since the last boot. Enter Setup and enter the new
memory size in the memory fields.

Memory Verify Error at ...

Indicates an error verifying a value already written to memory. Use the location along
with your system’s memory map to locate the bad chip.

OFFENDING ADDRESS NOT FOUND

This message is used in conjunction with the I/O CHANNEL CHECK and RAM
PARITY ERROR messages when the segment that has caused the problem cannot be
isolated.

B POST Messages

OFFENDING SEGMENT:

This message is used in conjunction with the I/O CHANNEL CHECK and RAM
PARITY ERROR messages when the segment that has caused the problem has been
isolated.

PRESS A KEY TO REBOOT

This will be displayed at the bottom screen when an error occurs that requires you to
reboot. Press any key and the system will reboot.

PRESS F1 TO DISABLE NMI, F2 TO REBOOT

If BIOS detects a non- maskable interrupt (NMI) during boot, this will allow you to
disable the NMI and continue to boot, or you can reboot the system with the NMI
enabled.

RAM PARITY ERROR - CHECKING FOR SEGMENT ...

Indicates a parity error in random access memory.
