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 ........................................................................ 30 BIOS Setup................................................................................... 30 Standard CMOS Setup ................................................................. 32 Advanced BIOS Features ............................
BIOS SETUP BIOS Introduction The Award BIOS (Basic Input/Output System) installed in your computer system’s ROM supports VIA 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 - Award WorkstationBIOS 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
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 0/1 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”. 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 CPU L1/L2 Cache Cache memory is additional memory that is much faster than conventional DRAM (system memory). CPUs from 486-type on up contain internal cache memory, and most, but not all, modern PCs have additional (external) cache memory. When the CPU requests data, the system transfers the requested data from the main DRAM into cache memory, for even faster access by the CPU. CPU L2 Cache ECC Checking When enabled, it allows ECC checking of the CPU L2 cache.
BIOS SETUP Boot Up NumLock Status This allows you to activate the NumLock function after you power up the system. Typematic Rate Setting When disabled, continually holding down a key on your keyboard will generate only one instance. When enabled, you can set the two typematic controls listed next. By default, this field is set to Disabled. Typematic Rate (Chars/Sec) When the typematic rate is enabled, the system registers repeated keystrokes speeds. Settings are from 6 to 30 characters per second.
BIOS SETUP Advanced Chipset Features This Setup menu controls the configuration of the chipset.
BIOS SETUP Phoenix - AwardBIOS CMOS Setup Utility CPU & PCI Bus Control PCI Master 0 WS Write PCI Delay Transaction Vlink mode selection Vlink 8x Support DRDY Timing Enabled Enabled By Auto Enabled Default ITEM HELP Menu Level Menu Level DRAM Clock / Drive Control This field provides settings related to DRAM. The fields are listed below. Current FSB Frequency The default setting of the FSB Frequency is 100MHz. Current DRAM Frequency The default setting of the DRAM Frequency is 266MHz.
BIOS SETUP Write to Read CMD (Twtr) The default time setting is 1T/2T. Write Recovery Time The default time setting is 4T. DRAM Command Rate The time to wait after a chip select before activate and read can be started. RDSAIT Mode The default time setting is Auto. RDSAIT Selection The default time setting is 03. AGP & P2P Bridge Control The fields related to AGP & P2P Bridge Control are listed below. AGP Aperture Size The field sets aperture size of the graphics.
BIOS SETUP Select Display Device By default, this field is set to CRT+LVDS. Panel Type By default, this field is set to 1024x768 18Bit SC02. Outport Port By default, this field is set to DI0. Dithering By default, this field is set to Disabled. TV H/W Layout By default, this field is set to Default. TV Type By default, this field is set to NTSC. TV Output Connector The field allows you to choose the TV output connector to be used.
BIOS SETUP Integrated Peripherals This section sets configurations for your hard disk and other integrated peripherals.
BIOS SETUP SuperIO Device Upon pressing Enter on this field, another window appears. Below are the fields shown with their respective default settings: Onboard FDC Controller – Enabled Onboard Serial Port 1 – 3F8/IRQ4 Onboard Serial Port 2 – 2F8/IRQ3 UART Mode Select – Normal 2nd Super I/O Device Upon pressing Enter on this field, another window appears.
BIOS SETUP Power Management Setup The Power Management Setup allows you to save energy of your system effectively.
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. Modem Use IRQ The default setting of this field is 3. Soft-Off by PWRBTN This field defines the power-off mode when using an ATX power supply.
BIOS SETUP IRQ/Event Activity Detect The items under this field 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. 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. Phoenix - Award WorkstationBIOS CMOS Setup Utility PnP/PCI Configurations PNP OS Installed No Reset Configuration Data Disabled Menu Level ITEM HELP Resources Controlled By IRQ Resources Auto (ESCD) Press Enter PCI/VGA Palette Snoop Assign IRQ for VGA Assign IRQ for USB Disabled Enabled Enabled Default is Disabled.

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.
