System Utilities
CMOS Setup Utility
CMOS setup is a hardware configuration program built into the system ROM, called the complementary metaloxide semiconductor (CMOS) Setup Utility. Since most systems are already properly configured and
optimized, there is no need to run this utility. You will need to run this utility under the following conditions.
When changing the system configuration settings
When redefining the communication ports to prevent any conflicts
When modifying the power management configuration
When changing the password or making other changes to the security setup
When a configuration error is detected by the system and you are prompted ("Run Setup"
message) to make changes to the CMOS setup
NOTE: If you repeatedly receive Run Setup messages, the battery may be bad. In this case, the system
cannot retain configuration values in CMOS. Ask a qualified technician for assistance.
CMOS setup loads the configuration values in a battery-backed nonvolatile memory called CMOS RAM. This
memory area is not part of the system RAM which allows configuration data to be retained when power is
turned off.
Before you run the CMOS Setup Utility, make sure that you have saved all open files. The system reboots
immediately after you close the Setup.
NOTE: CMOS Setup Utility will be simply referred to as “BIOS”, "Setup", or "Setup utility" in this guide.
The screenshots used in this guide display default system values. These values may not be the same
those found in your system.

Checkpoints
A checkpoint is either a byte or word value output to I/O port 80h. The BIOS outputs checkpoints throughout
bootblock and Power-On Self Test (POST) to indicate the task the system is currently executing. Checkpoints
are very useful in aiding software developers or technicians in debugging problems that occur during the preboot process.
Viewing BIOS checkpoints
Viewing all checkpoints generated by the BIOS requires a checkpoint card, also referred to as a POST card or
POST diagnostic card. These are ISA or PCI add-in cards that show the value of I/O port 80h on a LED
display. Checkpoints may appear on the bottom right corner of the screen during POST. This display method is
limited, since it only displays checkpoints that occur after the video card has been activated.
Bootblock Initialization Code Checkpoints
The Bootblock initialization code sets up the chipset, memory, and other components before system memory
is available. The following table describes the type of checkpoints that may occur during the bootblock
initialization portion of the BIOS.
NOTE: Please note that checkpoints may differ between different platforms based on system configuration.
Checkpoints may change due to vendor requirements, system chipset or option ROMs from add-in PCI
devices.
CheckpointDescription
Before D1Early chipset initialization is done. Early super I/O initialization is done including
RTC and keyboard controller. NMI is disabled.
D0Go to flat mode with 4GB limit and GA20 enabled. Verify the bootblock checksum.
D1Perform keyboard controller BAT test. Check if waking up from power management
suspend state. Save power-on CPUID value in scratch CMOS.
D2Disable CACHE before memory detection. Execute full memory sizing module.
Verify that flat mode is enabled.
D3If memory sizing module not executed, start memory refresh and do memory sizing
in Bootblock code. Do additional chipset initialization. Re-enable CACHE. Verify
that flat mode is enabled.
D4Test base 512KB memory. Adjust policies and cache first 8MB. Set stack.
D5Bootblock code is copied from ROM to lower system memory and control is given to
it. BIOS now executes out of RAM.
D6Both key sequence and OEM specific method is checked to determine if BIOS
recovery is forced. Main BIOS checksum is tested. If BIOS recovery is necessary,
control flows to checkpoint E0. See Bootblock Recovery Code Checkpoints section
for more information.
D7Restore CPUID value back into register. The Bootblock-Runtime interface module
is moved to system memory and control is given to it. Determine whether to
execute serial flash.
D8The Runtime module is uncompressed into memory. CPUID information is stored
in memory.
D9Store the Uncompressed pointer for future use in PMM. Copying Main BIOS into
memory. Leaves all RAM below 1MB Read-Write including E000 and F000 shadow
areas but closing SMRAM.
DARestore CPUID value back into register. Give control to BIOS POST
(ExecutePOSTKernel). See POST Code Checkpoints section for more information.
Chapter 453
Page 62
Bootblock Recovery Code Checkpoints
The Bootblock recovery code gets control when the BIOS determines that a BIOS recovery needs to occur
because the user has forced the update or the BIOS checksum is corrupt. The following table describes the
type of checkpoints that may occur during the Bootblock recovery portion of the BIOS.
NOTE: Checkpoints may differ between different platforms based on system configuration. Checkpoints may
change due to vendor requirements, system chipset or option ROMs from add-in PCI devices.

DIM Code Checkpoints
The Device Initialization Manager (DIM) gets control at various times during BIOS POST to initialize different
system busses. The following table describes the main checkpoints where the DIM module is accessed.
NOTE: Checkpoints may differ between different platforms based on system configuration. Checkpoints may
change due to vendor requirements, system chipset or option ROMs from add-in PCI devices.
CheckpointDescription
2AInitialize different buses and perform the following functions: Reset, Detect, and
Disable (function 0); Static Device Initialization (function 1); Boot Output Device
Initialization (function 2). Function 0 disables all device nodes, PCI devices, and PnP
ISA cards. It also assigns PCI bus numbers. Function 1 initializes all static devices
that include manual configured onboard peripherals, memory and I/O decode windows
in PCI-PCI bridges, and noncompliant PCI devices. Static resources are also
reserved. Function 2 searches for and initializes any PnP, PCI, or AGP video devices.
38Initialize different buses and perform the following functions: Boot Input Device
Initialization (function 3); IPL Device Initialization (function 4); General Device
Initialization (function 5). Function 3 searches for and configures PCI input devices
and detects if system has standard keyboard controller. Function 4 searches for and
configures all PnP and PCI boot devices. Function 5 configures all onboard
peripherals that are set to an automatic configuration and configures all remaining
PnP and PCI devices.
While control is in the different functions, additional checkpoints are output to port 80h as a word value to
identify the routines under execution. The low byte value indicates the main POST Code Checkpoint. The
high byte is divided into two nibbles and contains two fields. The details of the high byte of these checkpoints
are as follows:
HIGH BYTE XY
The upper nibble 'X' indicates the function number that is being executed. 'X' can be from 0 to 7.
0 = func#0, disable all devices on the BUS concerned.
1 = func#1, static devices initialization on the BUS concerned.
2 = func#2, output device initialization on the BUS concerned.
3 = func#3, input device initialization on the BUS concerned.
4 = func#4, IPL device initialization on the BUS concerned.
5 = func#5, general device initialization on the BUS concerned.
6 = func#6, error reporting for the BUS concerned.
7 = func#7, add-on ROM initialization for all BUSes.
8 = func#8, BBS ROM initialization for all BUSes.
The lower nibble 'Y' indicates the BUS on which the different routines are being executed. 'Y' can be from 0 to
5.
0 = Generic DIM (Device Initialization Manager).
1 = On-board System devices.
2 = ISA devices.
3 = EISA devices.
4 = ISA PnP devices.
5 = PCI devices.

Beep Codes
Beep codes are used by the BIOS to indicate a serious or fatal error to the end user. Beep codes are used
when an error occurs before the system video has been initialized. Beep codes will be generated by the
system board speaker, commonly referred to as the PC speaker.
AMIBIOS displays the checkpoints in the bottom right corner of the screen during POST. This display method
is limited, since it only displays checkpoints that occur after the video card has been activated.
Not all computers using AMIBIOS enable this feature. In most cases, a checkpoint card is the best tool for
viewing AMIBIOS checkpoints.
Beep SymptomCause and Description
One short beepSystem is ready.
System is OK.
Continuous one long beepMemory not installed or memory error.
One long beep and two short beeps
then repeat.
One long beep then two short beepBIOS damaged.
Two short beeps CMOS damaged.
VGA not installed or VGA error.
Graphics card error/not installed, graphics card memory error or
graphics card BIOS checksum error.
BIOS is damaged, BIOS POST jumps to Boot Block to execute the
default procedures.

1,3Reseat the memory, or replace with known good modules.
6,7Fatal error indicating a serious problem with the system. Consult your system
manufacturer. Before declaring the motherboard beyond all hope, eliminate the
possibility of interference by a malfunctioning add-in card. Remove all expansion
cards except the video adapter.
If beep codes are generated when all other expansion cards are absent,
consult your system manufacturer’s technical support.
If beep codes are not generated when all other expansion cards are
absent, one of the add-in cards is causing the malfunction. Insert the cards back
into the system one at a time until the problem happens again. This will reveal
the malfunctioning card.
8If the system video adapter is an add-in card, replace or reseat the video adapter. If
the video adapter is an integrated part of the system board, the board may be faulty.
