CMOS Setup Utility
CMOS Setup Utility is a hardware configuration program built into the system ROM. Since most systems are already properly configured and optimized, there is normally no need to run this utility. You will need to run this utility under the following conditions: · When changing the system configuration including: · · · · · · · Setting the system time and date Configuring the system drives and peripherals Specifying the boot device sequence Configuring the power management modes Setting up system passwords or making other changes to the security setup
When trying to resolve IRQ conflicts When a configuration error is detected by the system and you are prompted ("Run Setup" message) to make changes to the BIOS settings.
The Setup Utility 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. The values take effect when the system is booted. POST uses these values to configure the hardware. If the values and the actual hardware do not agree, POST generates an error message. You must run this utility to change the hardware settings from the default or current configuration. IMPORTANT If you repeatedly receive "Run Setup" messages, the RTC battery located on the mainboard (BT1) may be defective. In this case, the system cannot retain configuration values in CMOS. Replace the RTC battery with a new one.
NOTE
For ease of reading, CMOS Setup Utility will be simply referred to as "Setup" or "Setup Utility" in this Service Guide.

Troubleshooting
This chapter lists the POST error indicators and BIOS beep codes, as well general troubleshooting instructions.
Hardware Diagnostic Procedure
1. 2. 3. Obtain as much detail as possible about the symptoms of the system failure. Verify the symptoms by attempting to recreate the failure by running the diagnostic tests or repeating the same operation. Refer to "Power System Check" procedure on the next section and the "Beep Codes" section on page 76 to determine which corrective action to take.
System Check Procedures
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.
Power System Check
If the system can be powered on, skip this section. Proceed to the "System Internal Inspection" procedure on the next page. If the system will not power on, do the following: · · Check if the power cable is properly connected to the AC power jack and a functional AC power source. Check if the voltage selector switch is set to the correct voltage setting.
System External Inspection
1. 2. 3. Inspect the power and LED indicators on the front panel. Go to "Front View" section on page 3 for the location and description of the LED behaviour. Make sure that the ventilation slots on the rear panel are not blocked. Make sure that there is no point of contact in the system that can cause a power short. If the cause of the failure is still can not be determined, perform the "System Internal Inspection" procedure described on the next page.

System Internal Inspection
1. 2. 3. 4. 5. 6. 7. 8. Turn off the power to the computer and all peripherals. Unplug the power cord from the computer. Unplug the network cable and all connected peripheral devices from the computer.
Place the computer on a flat, steady surface. Remove the side panel as described in page 20. Verify that the processor, memory module(s), and expansion board(s) are properly seated. Verify that all power and data cables are firmly and properly attached to the installed drives. Verify that all cable connections inside the system are firmly and properly attached to their appropriate mainboard connectors. 9. Verify that all components are Acer-qualified and supported. 10. Reinstall the side panel. 11. Power on the system. If the cause of the failure is still can not be determined, review the POST messages and BIOS checkpoints during the system startup.
Checkpoints
A checkpoint is either a byte or word value output to I/O port 80h. The BIOS outputs checkpoints during bootblock and Power-On Self Test (POST) to indicate the task the system is currently executing. Checkpoints are 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 a checkpoint 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 is limited, since it only displays checkpoints that occur after the video card has been activated. 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.
Boot Block Initialization Code Checkpoints
The boot block 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 boot block initialization portion of the BIOS. Checkpoint Before D1 D1 D0 D2 D3 Description Early chipset initialization is done. Early super I/O initialization is done including RTC and keyboard controller. NMI is disabled. Perform keyboard controller BAT test. Check if waking up from power management suspend state. Save power-on CPUID value in scratch CMOS. Go to flat mode with 4GB limit and GA20 enabled. Verify the bootblock checksum. Disable CACHE before memory detection. Execute full memory sizing module. Verify that flat mode is enabled. If memory sizing module not executed, start memory refresh and do memory sizing in bootblock code. Do additional chipset initialization. Re-enable CACHE. Verify that flat mode is enabled. Test base 512 KB memory. Adjust policies and cache first 8 MB. Set stack.

Checkpoint D5 D6
Description Bootblock code is copied from ROM to lower system memory and control is given to it. BIOS now executes out of RAM. Both key sequence and OEM specific method is checked to determine if BIOS recovery is forced. Main BIOS checksum is tested. If BIOS recovery is necessary, control flows to checkpoint E0. See the "Boot Block Recovery Code Checkpoints" section for 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 1 MB Read-Write including E000 and F000 shadow areas but closing SMRAM. Restore CPUID value back into register. Give control to BIOS POST (ExecutePOSTKernel). See the "POST Code Checkpoints" section for more information.

Boot Block Recovery Code Checkpoints
The boot block recovery code gets control when the BIOS determines that a BIOS recovery is required because the user has forced the update or the BIOS checksum is corrupt. Refer to "BIOS Recovery" section on page 77 for more information. The following table describes the type of checkpoints that may occur during the boot block recovery portion of the BIOS. Checkpoint E0 E9 EA EB EF E9 or EA F0 F1 F2 F3 F5 FA FB F4 FC FD FF Description 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. 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. Determine information about root directory of recovery media. 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.
