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 CPU L1 and 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. These items allow you to enable (speed up memory access) or disable the cache function.
BIOS SETUP Boot Up NumLock Status This allows you to activate the NumLock function after you power up the system. Gate A20 Option This field allows you to select how Gate A20 is worked. Gate A20 is a device used to address memory above 1 MB. 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.
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. Console Redirection Set the Console Redirection from COM port to UNIX terminal on BIOS boot up. By default, the setting is enabled. Baud Rate The default value of the Baud Rate is 19200. Agent Connect Via By default, this item is set to NULL.
BIOS SETUP Advanced Chipset Features This Setup menu controls the configuration of the chipset.
BIOS SETUP System Memory Frequency This field sets the frequency of the DRAM memory installed. The default setting is Auto. The other settings are DDR266, DDR333, 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.

IDE DMA Transfer Access Use this field to enable or disable IDE DMA transfer access. 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.
BIOS SETUP PATA IDE Mode This item allows you to select the parallel ATA channel. Setting options are Primary and Secondary. SATA Port This feature allows users to view the SATA port as primary or secondary channel. USB Controller The options for this field are Enabled and Disabled. By default, this field is set to Enabled. USB 2.0 Controller The options for this field are Enabled and Disabled. By default, this field is set to Disabled. In order to use USB 2.0, necessary OS drivers must be installed first.
BIOS SETUP 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. This option allows you to select the onboard FDD port. Onboard Serial/Parallel Port These fields allow you to select the onboard serial and parallel ports and their addresses.
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 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.
