CMOS Setup Utility

CMOS setup is a hardware 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 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.

on page 24.

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.

Chapter 4 71

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 two 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.

72 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 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 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.

D0 Early Boot Strap Processor (BSP) initialization like microcode update, frequency and other

CPU critical initialization. Early chipset initialization is done.

D1 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.

D2 Verify the boot block checksum. System will hang here if checksum is bad.

D3 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.

D4 Test base 512KB memory. Adjust policies and cache first 8MB. Set stack.

D5 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.

D6 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.

D7 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.

D8 The Runtime module is uncompressed into memory. CPUID information is stored in memory.

D9 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 73

DA Restore CPUID value back into register. Give control to BIOS POST (ExecutePOSTKernel).

See POST Code Checkpoints section of document for more information.

DC System is waking from ACPI S3 state.

E1-E8 EC-
EE

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.

Checkpoint Description

74 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

E0 Initialize 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.

E9 Set up floppy controller and data. Attempt to read from floppy.

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

EB Disable ATAPI hardware. Jump back to checkpoint E9.

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

F0 Search for pre-defined recovery file name in root directory.

F1 Recovery file not found.

F2 Start reading FAT table and analyze FAT to find the clusters occupied by the recovery file.

F3 Start reading the recovery file cluster by cluster.

F5 Disable L1 cache.

FA Check the validity of the recovery file configuration to the current configuration of the flash

part.

FB 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.

F4 The recovery file size does not equal the found flash part size.

FC Erase the flash part

FD Program the flash part.

FF 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.

Chapter 4 75

BIOS Recovery

AMIBIOS supports a "recovery flash" mode, which can be used to flash update a BIOS from the boot block.
This is used to update a BIOS image without the need to boot to an operating system. The following is the
process that user should follow to flash BIOS ROM.

1. Put the AMIBoot.ROM to a bootable USB flash drive(Disk on Key, DOK).

2. Install the DOK to the system.

3. Press power button to boot the system and then press Ctrl + Home.

4. The BIOS recovery function will be executed.

5. After BIOS is updated completely, the system will auto reboot.
