BIOS SETUP BIOS Introduction The Award BIOS (Basic Input/Output System) installed in your computer system’s ROM supports Intel® Pentium® 4 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 display
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 board 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 Primary HDDs / IDE Secondary HDDs The onboard PCI IDE connectors provide Primary and Secondary channels for connecting up to four IDE hard disks or other IDE devices. Each channel can support up to two hard disks; the first is the “Master” and the second is the “Slave”.
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 Hard Disk Boot Priority This item allows you to set the priority for hard disk boot. When you press enter, the selections shows the current hard disks used in your system as well as the “Bootable Add-in Card” that is relevant to other boot sources media such as SCSI cards and LAN cards. Virus Warning This item protects the boot sector and partition table of your hard disk against accidental modifications. If an attempt is made, the BIOS will halt the system and display a warning message.
BIOS SETUP Swap Floppy Drive This item allows you to determine whether or not to enable Swap Floppy Drive. When enabled, the BIOS swaps floppy drive assignments so that Drive A becomes Drive B, and Drive B becomes Drive A. By default, this field is set to Disabled. Boot Up Floppy Seek This feature controls whether the BIOS checks for a floppy drive while booting up. If it cannot detect one (either due to improper configuration or its absence), it will flash an error message.
BIOS SETUP 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. OS Select for DRAM > 64MB This option allows the system to access greater than 64MB of DRAM memory when used with OS/2 that depends on certain BIOS calls to access memory. The default setting is Non-OS/2.
BIOS SETUP Advanced Chipset Features This Setup menu controls the configuration of the chipset. Phoenix - AwardBIOS CMOS Setup Utility Advanced Chipset Features DRAM Timing Selectable CAS Latency Time Active to Precharge Delay DRAM RAS# to CAS# Delay DRAM RAS# Precharge Memory Frequency For System BIOS Cacheable Video BIOS Cacheable Memory Hole At 15M-16M AGP Aperture Size (MB) By SPD 2.
BIOS SETUP Memory Frequency For This field sets the frequency of the DRAM memory installed. The default setting is Auto. The other settings are DDR266,DDR320 and DDR400. System BIOS Cacheable The setting of Enabled allows caching of the system BIOS ROM at F000h-FFFFFh, resulting in better system performance. However, if any program writes to this memory area, a system error may result.

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. OnChip Primary/Secondary PCI IDE The integrated peripheral controller contains an IDE interface with support for two IDE channels. Select Enabled to activate each channel separately. IDE Primary/Secondary Master/Slave PIO These fields allow your system hard disk controller to work faster.
BIOS SETUP AC97 Audio The default setting of the AC97 Audio is Auto. CSA LAN (Giga-LAN) The field enables or disables this Intel Giga BaseT Ethernet controller. Init Display First By default, the system initializes the PCI Slot VGA when the system boots. Onboard FDC Controller Select Enabled if your system has a floppy disk controller (FDC) installed on the board and you wish to use it. If you install an add-in FDC or the system has no floppy drive, select Disabled in this field.
BIOS SETUP Power Management Setup The Power Management Setup allows you to save energy of your system effectively.
BIOS SETUP 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. Modem Use IRQ This field sets the IRQ used by the Modem. By default, the setting is 3. Suspend Mode When enabled, and after the set time of system inactivity, all devices except the CPU will be shut off.
BIOS SETUP Reload Global Timer Events The HDD, FDD, COM, LPT Ports, and PCI PIRQ are I/O events which 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. When the operating system is ready to respond to the request, it interrupts itself and performs the service.
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 Hardware Monitor CPU Warning Temperature System Temp. CPU Temp CPU FAN Speed (FAN1) System FAN Speed (FAN2) System FAN Speed (FAN3) Vcore(V) +3.3V +5V +12V -12V Shutdown Temperature CPU Fan Failure Warning Sys. Fan Failure Warning Aux.
BIOS SETUP Frequency/Voltage Control This section shows the user how to configure the processor frequency. Phoenix - AwardBIOS CMOS Setup Utility Frequency/Voltage Control CPU Clock Ratio Auto Detect PCI Clk 14X Disabled Spread Spectrum Disabled ITEM HELP Menu Level CPU Clock Ratio The CPU Ratio, also known as the CPU bus speed multiplier, can be configured through this field. The default setting is 14X. This parameter can be used in conjunction with the above field to change the processor’s speed.
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 Setup 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.
