BIOS SETUP BIOS Setup This chapter describes the different settings available in the Award BIOS that comes with the board. The topics covered in this chapter are as follows: BIOS Introduction ........................................................................ 26 BIOS Setup ................................................................................... 26 Standard CMOS Setup ................................................................. 28 Advanced BIOS Features .................................
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 To set the date, highlight the “Date” field and use the PageUp/ PageDown or +/- keys to set the current time. 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 Serial ATA connectors provide Primary and Secondary channels for connecting up to four Serial ATA hard disks .
BIOS SETUP Video This field selects the type of video display card installed in your system. You can choose the following video display cards: EGA/VGA For EGA, VGA, SEGA, SVGA or PGA monitor adapters. (default) CGA 40 Power up in 40 column mode. CGA 80 Power up in 80 column mode. MONO For Hercules or MDA adapters. 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.
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 Hyper-Threading Technology Hyper-Threading Technology enables two logical processors on a single physical processor by replicating, partitioning, and sharing the resources within the Intel NetBurst microarchitecture pipeline. 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.
BIOS SETUP Typematic Delay (Msec) When the typematic rate is enabled, this item allows you to set the time interval for displaying the first and second characters. By default, this item is set to 250msec. Security Option This field allows you to limit access to the System and Setup. The default value is Setup. When you select System, the system prompts for the User Password every time you boot up.
BIOS SETUP Advanced Chipset Features This Setup menu controls the configuration of the chipset.
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 IDE HDD Block Mode This field allows your hard disk controller to use the fast block mode to transfer data to and from your hard disk drive. IDE DMA Transfer Access This field, by default, is enabled OnChip Secondary PCI IDE This field, by default, is enabled IDE Primary/Secondary Master/Slave PIO These fields allow your system hard disk controller to work faster.
BIOS SETUP Onboard Serial/Parallel Port These fields allow you to select the onboard serial and parallel ports and their addresses. The default values for these ports are: Serial Port 1 3F8/IRQ4 Serial Port 2 2F8/IRQ3 Parallel Port 378H/IRQ7 UART Mode Select This field determines the UART 2 mode in your computer. The default value is Normal. Other options include IrDA and ASKIR. Parallel Port Mode This field allows you to determine parallel port mode function.
BIOS SETUP Power Management Setup Phoenix - AwardBIOS CMOS Setup Utility Power Management Setup ACPI Function Enabled ACPI Suspend Power Management Video Off Method Video Off In Suspend Suspend Type Modem Use IRQ Suspend Mode HDD Power Down Soft-Off by PWR-BTTN CPU THRM-Throttling Wake Up by PCI card Power On by Ring Resume by Alarm Date (of Month) Alarm Time (hh:mm:ss) Alarm S3(STR) User Define V/H SYNC+Blank Yes Stop Grant 3 Disabled Disabled Instant-Off 75.
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. Suspend Type The default setting for the Suspend Type field is Stop Grant. Modem Use IRQ This field sets the IRQ used by the Modem.
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 Phoenix - AwardBIOS CMOS Setup Utility PC Health Status Shutdown Temperature CPU Warning Temperature System Temp CPU Temp System Fan Speed CPU Fan Speed Vcore 12 V 1.8 V 5 V 3.3 V VBAT (V) 5VSB(V) Disabled Disabled 32°C/89°F 39°C/102°F 4000 RPM 4000 RPM 1.24 V 12.03 V 1.92 V 4.99 V 3.15 V 3.13 V 5.29 V ITEM HELP Menu Level > CPU Warning Temperature This field allows the user to set the temperature so that when the temperature is reached, the system sounds a warning.
BIOS SETUP Frequency/Voltage Control Phoenix - AwardBIOS CMOS Setup Utility Frequency/Voltage Control CPU Clock Ratio Unlock Disabled CPU Clock Ratio Auto Detect PCI Clk Spread Spectrum CPU Host / SRC / PCI Clock 8x Disabled Disabled Default ITEM HELP Menu Level > CPU Clock Ratio Unlock This field has a default setting of Disabled. When enabled, it allows the CPU clock ratio setting in the next field to be changed to a ‘lower’ ratio.
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/User 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 that 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.
