BIOS SETUP BIOS Introduction The Award BIOS (Basic Input/Output System) installed in your computer system’s ROM supports Intel processors. The BIOS provides critical low-level support for a standard device such as disk drives, serial ports and parallel ports. It also adds virus and password protection as well as special support for detailed fine-tuning of the chipset controlling the entire system.
BIOS SETUP Phoenix - AwardBIOS CMOS Setup Utility Standard CMOS Features Advanced BIOS Features Advanced Chipset Features Integrated Peripherals Power Management Setup PnP/PCI Configurations PC Health Status Frequency/Voltage Control Load Fail-Safe Defaults Load Optimized Defaults Set Supervisor Password Set User Password Save & Exit Setup Exit Without Saving ESC : Quit F10 : Save & Exit Setup Ç È Æ Å : Select Item Time, Date, Hard Disk Type… The section below the setup items of the Main Menu displays
BIOS SETUP Standard CMOS Setup “Standard CMOS Setup” choice allows you to record some basic hardware configurations in your computer system and set the system clock and error handling. If the motherboard is already installed in a working system, you will not need to select this option. You will need to run the Standard CMOS option, however, if you change your system hardware configurations, the onboard battery fails, or the configuration stored in the CMOS memory was lost or damaged.
BIOS SETUP Time The time format is: Hour : 00 to 23 Minute : 00 to 59 Second : 00 to 59 To set the time, highlight the “Time” field and use the / or +/- keys to set the current time. IDE Channel Master/Slave The onboard PCI IDE connector provides Primary and Secondary channels for connecting up to two IDE hard disks or other IDE devices. Press to configure the hard disk. The selections include Auto, Manual, and None. Select ‘Manual’ to define the drive information manually.
BIOS SETUP Halt On This field determines whether or not the system will halt if an error is detected during power up. No errors The system boot will not be halted for any error that may be detected. All errors Whenever the BIOS detects a non-fatal error, the system will stop and you will be prompted.
BIOS SETUP Advanced BIOS Features This section allows you to configure and improve your system and allows you to set up some system features according to your preference.
BIOS SETUP Quick Power On Self Test When enabled, this field speeds up the Power On Self Test (POST) after the system is turned on. If it is set to Enabled, BIOS will skip some items. First/Second/Third Boot Device These fields determine the drive that the system searches first for an operating system. The options available include LS120, Hard Disk, CDROM, ZIP100, USB-FDD, USB-ZIP, USB-CDROM, LAN and Disable.
BIOS SETUP APIC Mode APIC stands for Advanced Programmable Interrupt Controller. The default setting is Enabled. MPS Version Control for OS This option is specifies the MPS (Multiprocessor Specification) version for your operating system. MPS version 1.4 added extended configuration tables to improve support for multiple PCI bus configurations and improve future expandability. The default setting is 1.4.
BIOS SETUP Advanced Chipset Features This Setup menu controls the configuration of the chipset.
BIOS SETUP DRAM RAS# Precharge This option sets the number of cycles required for the RAS to accumulate its charge before the SDRAM refreshes. The default setting for the Active to Precharge Delay is 3. Precharge Delay (tRAS) The default setting for the Precharge Delay is 9. System Memory Frequency The default setting is 400MHz. SLP_S4# Assertion Width The default setting is 1 to 2 Sec.
BIOS SETUP Panel Scaling The default setting is Auto. The options available include On and Off. Onboard PCI-E LAN By default, this setting is enabled. LAN PXE Option ROM By default, this setting is All Disabled. The options available include All Disabled and ICH6 integrated Lan.
BIOS SETUP Integrated Peripherals This section sets configurations for your hard disk and other integrated peripherals. The first screen shows three main items for user to select. Once an item selected, a submenu appears. Details follow.

BIOS SETUP On-Chip Serial ATA Setting The fields under the SATA setting includes On-Chip Serial ATA (Auto), PATA IDE Mode (Secondary) and SATA Port (PO, P2 is Primary). USB Controller The options for this field are Enabled and Disabled. By default, this field is set to Enabled. USB 2.0 Controller The options for this field are Enabled and Disabled. By default, this field is set to Enabled. In order to use USB 2.0, necessary OS drivers must be installed first.
BIOS SETUP Onboard Serial Port These fields allow you to select the onboard serial ports and their addresses. The default values for these ports are: Serial Port 1 3F8/IRQ4 Serial Port 2 2F8/IRQ3 Serial Port 3 2B0/IRQ11 Serial Port 4 2B8/IRQ10 PWRON After PWR-Fail This field sets the system power status whether on or off when power returns to the system from a power failure situation.

BIOS SETUP Video Off Method This field defines the Video Off features. There are three options. V/H SYNC + Blank Default setting, blank the screen and turn off vertical and horizontal scanning. DPMS Allows BIOS to control the video display. Blank Screen Writes blanks to the video buffer. Video Off In Suspend When enabled, the video is off in suspend mode. The default setting is Yes. Suspend Type The default setting for the Suspend Type field is Stop Grant.
BIOS SETUP Resume by Alarm This field enables or disables the resumption of the system operation. When enabled, the user is allowed to set the Date and Time. Reload Global Timer Events The HDD, FDD, COM, LPT Ports, and PCI PIRQ are I/O events that can prevent the system from entering a power saving mode or can awaken the system from such a mode. When an I/O device wants to gain the attention of the operating system, it signals this by causing an IRQ to occur.
BIOS SETUP PNP/PCI Configurations This option configures the PCI bus system. All PCI bus systems on the system use INT#, thus all installed PCI cards must be set to this value.
BIOS SETUP PC Health Status This section shows the parameters in determining the PC Health Status. These parameters include temperatures, fan speeds and voltages.

Phoenix - AwardBIOS CMOS Setup Utility Frequency/Voltage Control Auto Detect PCI Clk Disabled Spread Spectrum Modulated Disabled ITEM HELP Menu Level > Auto Detect PCI Clk This field enables or disables the auto detection of the PCI clock. Spread Spectrum Modulated This field sets the value of the spread spectrum. The default setting is Disabled. This field is for CE testing use only.
BIOS SETUP Load Fail-Safe Defaults This option allows you to load the troubleshooting default values permanently stored in the BIOS ROM. These default settings are non-optimal and disable all high-performance features. Load Optimized Defaults This option allows you to load the default values to your system configuration. These default settings are optimal and enable all high performance features. Set Supervisor Password These two options set the system password.

APPENDIX Appendix A. I/O Port Address Map Each peripheral device in the system is assigned a set of I/O port addresses which also becomes the identity of the device. The following table lists the I/O port addresses used.
APPENDIX B. Interrupt Request Lines (IRQ) Peripheral devices use interrupt request lines to notify CPU for the service required. The following table shows the IRQ used by the devices on board.
APPENDIX C. Watchdog Timer Configuration The WDT is used to generate a variety of output signals after a user programmable count. The WDT is suitable for use in the prevention of system lock-up, such as when software becomes trapped in a deadlock. Under these sorts of circumstances, the timer will count to zero and the selected outputs will be driven. Under normal circumstance, the user will restart the WDT at regular intervals before the timer counts to zero.
