System Utilities
CMOS Setup Utility
CMOS setup is a hard ware configuration program built into the system ROM, called the complementary
metal- oxide 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 condition.
• 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 screen shots used in this guide display default system values. These values may not be the same
those found in your system.

System Trouble shooting
This chapter provides instructions on how to trouble shoot 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.
2. Verify the symptoms by attempting to recreate the failure by running the diagnostic tests or repeating
the same operation.
3. Refer to “Power System check” and “Beep Codes” to determine which corrective action to perform.
Chapter4
60
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.
2. Make sure that air flow is not blocked.
3. Make sure nothing in the system is making contact that could short out power.
4. 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.
2. Unplug the power cord from the power outlets.
3. Unplug the power cord from the system.
4. Unplug all peripheral cables from the system.
5. Place the system unit on a flat, stable surface.
6. Remove the system covers. For instructions on removing system covers, refer to “System Disassembly”.
7. Verify that components are properly seated.
8. Verify that all cable connectors inside the system are firmly and correctly attached to their appropriate
connectors.
9. 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.

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.

Symptom:
One short beep.
Memory not installed or memory error
Symptom:
Continuous one long beep.

Description:
System is OK.
Description:
Something is wrong with the memory installed.
Note that there could also be something wrong with
just accessing the memory (ie the motherboard has a
problem).

Description:
The motherboard is not able to access the video
card for some reasons. Either the video card is not
working, its memory is not accessible, or its BIOS
may be corrupt. This error code could also mean
something is wrong with the motherboard.
Description:
BIOS damaged. Processor jump to BootBlock to
execute the default procedure.
Description:

62
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 pre-
boot 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 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.

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.
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

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.
