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 ........................................................................ 28 BIOS Setup................................................................................... 28 Standard CMOS Setup ................................................................. 30 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 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 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.
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 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 Floppy, LS120, Hard Disk, CDROM, ZIP100, USB-Floppy, USB-ZIP, USB-CDROM, LAN and Disable.
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 On-Chip VGA Setting The fields under the On-Chip VGA Setting and their default settings are: PEG/On Chip VGA Control: Auto On-Chip Frame Buffer Size: 8MB DVMT Mode: DVTM DVMT/Fixed Memory Size: 128MB SDVO Device Setting: (LVDS, DVI, Dual DVI, CRT); Dual LVDS [onboard + ID390] Remarks: Set to LVDS for ID390, Set to CRT for ID390C, Set to DVI for ID391/ID392/ID391D/ID392D.
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). AC97 Audio Select This field, by default, is set to Auto. Power ON Function This field is related to how the system is powered on – such as with the use of conventional power button, keyboard or hot keys. The default is BUTTON ONLY.
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 UART Mode Select This field determines the UART 2 mode in your computer. The default value is Normal. Other options include IrDA and ASKIR. 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 PC Health Status Shutdown Temperature CPU Warning Temperature Current System Temp Current CPU Temp FAN1 Speed FAN2 Speed Vcore(V) 12 V 1.8V +5V -12V 3.3V VBAT (V) 5VSB(V) 1st Smart Fan Temperature 2st Smart Fan Temperature Disabled Disabled 45°C/113°F 45°C/113°F 5400 RPM 5400 RPM 1.02 V 1.32 V 1.8V 5.

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.
