System Utilities

AMI BIOS Setup Utility

BIOS setup is a hardware configuration program built into the system's Basic Input/Output System (BIOS).
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 BIOS 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.

BIOS 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 AMI BIOS Setup Utility, make sure that you have saved all open files. The system reboots
immediately after you close the Setup.

NOTE: AMI BIOS Setup Utility will be simply referred to as "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.

logs during the system startup.

42 Chapter 4

System Diagnosis

Hardware diagnostic program

The purpose of the hardware diagnostic program is to check hardware problems. It executes simple tests of
each hardware component to make sure the hardware is not the source of the problem. If hardware problems,
such as a fan, LED board, hard disk drive, memory; are confirmed, the diagnostic program can detect the
specific component causing the problem. The program needs to saved in a bootable USB device.

To run the diagnostic program:

1. Turn off the system.

2. Prepare a bootable USB device by copying or downloading the “ANNIE.GHO” diagnostic utility to the USB

device. The diagnostic utility may be obtained from the CD that came with the system.

3. Plug the bootable USB device to any USB port on the rear of the system.

4. Power on the system. The system status indicator blinks blue.

5. Immediately press and release the Recovery/reset button with the paper clip end. The system status

indicator blinks red and immediately starts the diagnostic process:

a. Onboard memory flash check

b. HDD account check

c. Memory size check (1024 or 2048 MB)

d. Fan speed check

e. CPU temperature check

f. MB voltage check

g. Backplane board temperature check

h. PQAF system test

i. PQAF memory test

j. PQAF HDD test

k. Read SN from DMI data check

l. End test

During the diagnostic process, the result of the test displays on the HDD status indicators. The
indicator(s) blinks blue when the system has passed each diagnostic test and blinks red when an error
condition occurs. After the system has completed the diagnostic procedure the HDD status indicators light
purple.

Debug card

The debug card is a diagnostic tool for technicians to configure the system BIOS settings and conveniently
troubleshoot various problems. This card can help you track the progress of a Power-On Self Test (POST) and
discover the cause of errors during system operations. The debug card connects to the system via its debug
card cable connector. It includes a VGA port for connecting an external monitor to view BIOS output
checkpoints. The debug card also provides a PS/2 mouse port, PS/2 keyboard port and a serial port.

For more information on how to connect the debug card to the system, refer to “Entering the BIOS Setup
Utility” on page 10.

44 Chapter 4

POST Code Checkpoints

The Power-On Self Test (POST) is a BIOS procedure that boots the system, initializes and diagnoses the
system components, and controls the operation of the power-on password option. If POST discovers errors in
system operations at power-on, it displays error messages, generates a checkpoint code at port 80h or even
halts the system if the error is fatal.

The main components on the system board that must be diagnosed and/or initialized by POST to ensure
system functionality are as follows:

 Microprocessor with built-in numeric coprocessor and cache memory subsystem

 Direct memory access (DMA) controller (8237 module)

 Interrupt system (8259 module)

 Three programmable timers (system timer and 8254 module)

 ROM subsystem

 RAM subsystem

 CMOS RAM subsystem and real time clock/calendar with battery backup

When POST executes a task, it uses a series of preset numbers called checkpoints to be latched at port 80h,
indicating the stages it is currently running. This latch can be read and shown on an external monitor
connected to the debug card.

Viewing BIOS checkpoints

Viewing all checkpoints generated by the BIOS requires a debug card and an external monitor. Checkpoints
may appear on the bottom right corner of the screen during POST.

POST code checkpoints list

Bootblock initialization code checkpoint

The following table describes the Award common tasks carried out by POST. An unique checkpoint number
denotes each task. .

Device Initialization Manager code checkpoints

The Device Initialization Manager (DIM) module gets control at various times during BIOS POST to initialize
different BUSes. The following table describes the main checkpoints where the DIM module is accessed:

Checkpoint Description

2A Initialize 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.

48 Chapter 4

Checkpoint Description

38 Initialize 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.

Perform the BIOS recovery if the BIOS flash ROM has become corrupted. The following sections provide
instructions on how to recover BIOS settings.

To create a BIOS Recovery disk:

1. Prepare a USB storage device.

2. Connect the USB storage device to a USB port on your computer.

3. Copy the target BIOS ROM file to a USB storage device.

4. Rename the target BIOS to “AMIBoot.ROM”.

5. Unplug the device.

To perform a BIOS recovery:

1. Create the BIOS Recovery disk as described in the previous section.

2. Connect the BIOS Recovery disk on the USB port on the system.

3. Depending on the current state of the system, do either of the following:

 If the system has crashed:

Power on the system. The system initializes the BIOS recovery process and the system will reboot
automatically after the flash update is completed.

 If the system has not crashed or if you want to revert BIOS to previous settings:

During POST, press <Ctrl> + <Home> during POST. This action will flash the BIOS from the USB
storage device to the system and reboot automatically after the flash update is completed.

4. Remove the BIOS Recovery disk.

Chapter 4 51

Clearing CMOS

To clear the BIOS configuration you need to short the JP3 Clear CMOS jumper on the mainboard.

1. Turn off the computer and all attached devices.

2. Remove the system cover. See “Removing the System Cover” on page 25.

3. Locate the JP3 Clear CMOS jumper on the mainboard.
