INSTALLATIONS 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 sort 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.

BIOS SETUP BIOS Setup This chapter describes the different settings available in the Award BIOS that comes with the motherboard. 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 various 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 Load Fail-Safe Defaults Load Optimized Defaults Set Supervisor 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 the control keys for this menu.
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 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 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 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. Small Logo (EPA) Show The EPA logo appears at the right side of the monitor screen when the system is 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. Onboard LAN Boot ROM This feature allows users to enable or disable the onboard LAN boot ROM. The default setting is Disabled Onboard FDC Controller Select Enabled if your system has a floppy disk controller (FDC) installed on the motherboard and you wish to use it.
BIOS SETUP Power Management Setup The Power Management Setup allows you to save energy of your system effectively.
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. Phoenix - AwardBIOS CMOS Setup Utility PnP/PCI Configurations PNP OS Installed No Init Display First Reset Configuration Data PCI Slot Disabled Resources Controlled By IRQ Resources Memory Resources PCI/VGA Palette Snoop Auto (ESCD) Press Enter Press Enter Disabled ITEM HELP Menu Level Default is Disabled.
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 CPU Warning Temperature Current System Temp. Current CPU Temp Current System FAN Speed Current CPU FAN Speed Vcore(V) Vtt Vcc3(V) +5V +12V -12V VBAT Disabled 45°C/113°F 30°C/86°F 0 RPM 0 RPM 1.18 V 2.57V 3.39V 5.13 V 11.12 V -12.19 V 3.
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.
