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.

This chapter provides instructions on how to troubleshoot system hardware problems.

Hardware Diagnostic Procedure
IMPORTANT:The diagnostic tests described in this chapter are only intended to test Acer products. Non-Acer
products, prototype cards, or modified options can give false errors and invalid system
responses.
1.

Obtain the failing symptoms in as much detail as possible.

Verify the symptoms by attempting to recreate the failure by running the diagnostic tests or repeating the
same operation.

Refer to “Power System check” and “Beep Codes” to determine which corrective action to perform.

Chapter 4

System Check Procedures
Power System Check
If the system will power on, skip this section. Refer to System External Inspection.
If the system will not power on, do the following:
•

Check if the power cable is properly connected to the system and AC source.

•

Check if the voltage selector switchis set to the correct voltage setting.

System External Inspection
1.

Inspect the LED indicators on the front panel, which can indicate the malfunction.

Make sure that air flow is not blocked.

Make sure nothing in the system is making contact that could short out power.

If the problem is not evident, continue with System Internal Inspection.

System Internal Inspection
1.

Turn off the system and all the peripherals connected to it.

Unplug the power cord from the power outlets.

Unplug the power cord from the system.

Unplug all peripheral cables from the system.

Place the system unit on a flat, stable surface.

Remove the system covers.For instructions on removing system covers, refer to “System Disassembly”.

Verify that components are properly seated.

Verify that all cable connectors inside the system are firmly and correctly attached to their appropriate
connectors.

Verify that all components are Acer-qualified and supported.

10. Replace the system covers.
11. Power on the system.
12. If the problem with the system is not evident, you can try viewing the POST messages and BIOS event
logs during the system startup.

Chapter 4

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 Symptom

Cause and Description

One short beep

System is ready.
System is OK.

Continuous one long beep

Memory not installed or memory error.

One long beep and two short beeps then
repeat.

VGA not installed or VGA error.
Graphics card error/not installed, graphics card memory
error or graphics card BIOS checksum error.

One long beep then one short beep

BIOS damaged.
BIOS is damaged, BIOS POST jumps to Boot Block to
execute the default procedures.

Two short beeps

CMOS damaged.
CMOS checksum error or CMOS battery loss occurs.

Chapter 4

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. 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.
Checkpoint

Description

Before D0

If boot block debugger is enabled, CPU cache-as-RAM functionality is enabled at this point.
Stack will be enabled from this point.

Early Boot Strap Processor (BSP) initialization like microcode update, frequency and other
CPU critical initialization. Early chipset initialization is done.

Early super I/O initialization is done including RTC and keyboard controller. Serial port is
enabled at this point if needed for debugging. NMI is disabled. Perform keyboard controller
BAT test. Save power-on CPUID value in scratch CMOS. Go to flat mode with 4GB limit and
GA20 enabled.

Verify the boot block checksum. System will hang here if checksum is bad.

Disable CACHE before memory detection. Execute full memory sizing module. If memory
sizing module not executed, start memory refresh and do memory sizing in Boot block code.
Do additional chipset initialization. Re-enable CACHE. Verify that flat mode is enabled.

Test base 512KB memory. Adjust policies and cache first 8MB. Set stack.

Bootblock code is copied from ROM to lower system memory and control is given to it. BIOS
now executes out of RAM. Copies compressed boot block code to memory in right
segments. Copies BIOS from ROM to RAM for faster access. Performs main BIOS
checksum and updates recovery status accordingly.

Both 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.

Restore 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.

The Runtime module is uncompressed into memory. CPUID information is stored in memory.

Store 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.

Chapter 4

Checkpoint

Description

Restore CPUID value back into register. Give control to BIOS POST (ExecutePOSTKernel).
See POST Code Checkpoints section of document for more information.

System is waking from ACPI S3 state.

E1-E8 ECEE

OEM memory detection/configuration error. This range is reserved for chipset vendors &
system manufacturers. The error associated with this value may be different from one
platform to the next.

Chapter 4

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.
Checkpoint

Description

controller is initialized. 8259 interrupt controller is initialized. L1 cache is enabled.

Set up floppy controller and data. Attempt to read from floppy.

Enable ATAPI hardware. Attempt to read from ARMD and ATAPI CDROM.

Disable ATAPI hardware. Jump back to checkpoint E9.

Read error occurred on media. Jump back to checkpoint EB.

Search for pre-defined recovery file name in root directory.

Recovery file not found.

Start reading FAT table and analyze FAT to find the clusters occupied by the recovery file.

Start reading the recovery file cluster by cluster.

Disable L1 cache.

Check the validity of the recovery file configuration to the current configuration of the flash
part.

Make 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.

The recovery file size does not equal the found flash part size.

Erase the flash part

Program the flash part.

The flash has been updated successfully. Make flash write disabled. Disable ATAPI
hardware. Restore CPUID value back into register. Give control to F000 ROM at
F000:FFF0h.
