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.

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
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. Checkpoint
sare 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 acheckpoint 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
islimited, since it only displays checkpoints thatoccur 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 includingRTC and

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 toit. BIOS
now executes out of RAM.
D6Both key sequence and OEM specific method is checked to determine if BIOSrecovery is
forced. Main BIOS checksum is tested. If BIOS recovery is necessary,control flows to
checkpoint E0. See Bootblock Recovery Code Checkpoints sectionfor more information.
D7Restore CPUID value back into register. The Bootblock-Runtime interf ace 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.

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
maychange due to vendor requirements, system chipset or option ROMs from add-in PCI devices.
CheckpointDescription
E0Initialize the floppy controller in the super I/O. Some interrupt vectors are initialized. DMA
controller is initialized. 8259 interrupt controller is initialized. L1 cache is enabled.
E9Set up floppy controller and data. Attempt to read from floppy.
EAEnable ATAPI hardware. Attempt to read from ARMD and ATAPI CDROM.
EBDisable ATAPI hardware. Jump back to checkpoint E9.
EFRead error occurred on media. Jump back to checkpoint EB.
F0Search for pre-defined recovery file name in root directory.
F1Recovery file not found.
F2Start reading FAT table and analyze FAT to find the clusters occupied by the recovery file.
F3Start reading the recovery file cluster by cluster.
F5Disable L1 cache.
FACheck the validity of the recovery file configuration to the current configuration of the flash
part.
FBMake flash write enabled through chipset and OEM specific method. Detect proper flash
part. Verify that the found flash part size equals the recovery file size.
F4The recovery file size does not equal the found flash part size.
FCErase the flash part
FDProgram the flash part.
FFThe flash has been updated successfully. Make flash write disabled. Disable ATAPI

The section explains how to set jumper for correct configuration of the mainboard.
Use the motherboard jumpers to set system configuration options. Jumpers withmore than one pin are
numbered. When setting the jumpers, ensure that the jumpercaps are placed on the correct pins.
The illustrations show a 2-pin jumper.When the jumper cap is placed on bothpins, the jumper is SHORT. I f yo u
re-move the jumper cap, or place the jumpercap on just one pin, the jumper is OPEN.
This illustration shows a 3-pin jumper.Pins 1 and 2 are SHORT.
Setting Jumper
Use the motherboard jumpers to set system configuration options. Jumpers with more Than one pin are
numbered. When setting the jumpers, ensure that the jumper caps are Placed on the correct pins.
