Chapter 2 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.
Entering CMOS setup 1. Turn on the server and the monitor. If the server is already turned on, close all open applications, then restart the server. 2. During POST, press Delete. If you fail to press Delete before POST is completed, you will need to restart the server. The Setup Main menu will be displayed showing the Setup’s menu bar. Use the left and right arrow keys to move between selections on the menu bar.
Setup Utility Menus The Setup Main menu includes the following main setup categories.
Product Information The Product Information menu displays basic information about the system. These entries are for your reference only and are not user-configurable. Parameter Description Processor Type Type of CPU installed on the system. Processor Speed Speed of the CPU installed on the system. System Memory Total size of system memory installed on the system. Product Name Product name of the system. System Serial Number Serial number of the system.
Standard CMOS Features Parameter Description System Date Set the date following the weekday-month-day-year format. System Time Set the system time following the hour-minute-second format. Halt On Determines whether the system will stop for an error during the POST.
Advanced BIOS Feature Parameter Description Option Quick Boot Allows you to decrease the time it takes to boot the computer by shortening or skipping certain standard booting process. Enabled Quiet Boot When enabled, the BIOS splash screen displays during startup. Enabled When disabled, the diagnostic screen displays during startup. Disabled Specifies the boot order from the available devices.
Advanced Chipset Features Parameter Description Option Intel EIST When enabled, this feature allows the OS to reduce power consumption. Enabled When disabled, the system operates at maximum CPU speed. Disabled When enabled, the processor disables code execution when a worm attempts to insert a code in the buffer preventing damage and worm propagation. Enabled Intel XD Bit Disabled When disabled, the processor forces the Execute Disable (XD) Bit feature flag to always return to 0.
Integrated Peripherals Parameter Description Onboard SATA Controller Enables or disables the onboard SATA controller. Option Enabled Disabled Onboard SATA Mode Select an operating mode for the onboard SATA. RAID Native IDE Onboard USB Controller Enables or disables the onboard USB controller.

BIOS Security Features Parameter Description Supervisor Password Indicates the status of the supervisor password. User Password Indicates the status of the user password. Change Supervisor Password Supervisor password prevents unauthorized access to the BIOS Setup Utility. Press Enter to change the Supervisor password. Setting a supervisor password 1. Use the up/down arrow keys to select Change Supervisor Password menu then press Enter. A password box will appear. 2.
Load Default Settings The Load Default Settings menu allows you to load the default settings for all BIOS setup parameters. Setup defaults are quite demanding in terms of resources consumption. If you are using low-speed memory chips or other kinds of low-performance components and you choose to load these settings, the system might not function properly.
Save & Exit Setup The Save & Exit Setup menu allows you to save changes made and close the Setup Utility.
Exit Without Saving The Exit Without Saving menu allows you to discard changes made and close the Setup Utility.

Chapter 4 System Troubleshooting 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. NonAcerproducts, prototype cards, or modified options can give false errors and invalid systemresponses. 1. Obtain the failing symptoms in as much detail as possible. 2.
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.
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.
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.
Checkpoint Description 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 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.
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.
BIOS Recovery 1. This function only effects when the BIOS BootBlock section is healthy. 2. Allow to execute recovery function media: FDD / USB storage / ODD. 3. The recovery media to support Boot function is unnecessary. 4. Recovery step as follow: 4-1. Copy the latest BIOS ROM file to the root directory of recovery media. 4-2. Rename the BIOS ROM file to be "AMIBOOT.ROM". 4-3. Insert the recovery device to system and then power on the system. 4-4.
