BIOS 3.1 BIOS Introduction The Award BIOS (Basic Input/Output System) installed in your computer system’s. The BIOS provides for a standard device such as disk drives, serial ports and parallel ports. It also adds password protection as well as special support for detailed fine-tuning of the chipset controlling the entire system. 3.2 BIOS Setup The Award BIOS provides a Setup utility program for specifying the system configurations and settings. The BIOS ROM of the system stores the Setup utility.
BIOS 3.3 Standard CMOS Features “Standard CMOS Features” allows you to record some basic hardware configurations in your computer system and set the system clock and error handling. If the CPU card 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, such as onboard battery fails, or the configuration stored in the CMOS memory was lost or damaged.
BIOS 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”. Press to configure the hard disk. The selections include Auto, Manual, and None. Select ‘Manual’ to define the drive information manually. You will be asked to enter the following items.
BIOS Halt On This field determines whether or not the system will halt if an error is detected during power up. All errors (default) Whenever the BIOS detects a non-fatal error, the system will stop and you will be prompted. No errors The system boot will not be halted for any error that may be detected. All, But Keyboard The system boot will not be halted for a keyboard error; it will stop for all other errors.
BIOS 3.4 Advanced BIOS Features 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. Setting: Enabled (Default), Disabled. First/ Second Boot Device These fields determine the drive that the system searches first for an operating system. The options available include Setting: Floppy, LS120, HDD-0, SCSI, CDROM, HDD-1, ZIP100, USB-FDD, USB-ZIP, USB-CDROM, USB-HDD, LAN and Disabled.
BIOS Boot Up NumLock Status It allows you to activate the NumLock function after you power up the system. Setting: On (Default), Off. Security Option It allows you to limit access to the System and Setup. When you select System, the system prompts for the User Password every time you boot up. When you select Setup, the system always boots up and prompts for the Supervisor Password only when the Setup utility is called up. Setting: Setup (Default), System.
BIOS 3.5 Advanced Chipset Features CAS Latency Time It allows CAS latency time in HCLKs as 2 or 2.5. The system board designer should set the values in this field, depending on the DRAM installed. Do not change the values in this field unless you change specifications of the installed DRAM or CPU. Setting: 2.5 (Default), 2. Interleave Select It allows you to Use the Interleave Select option to specify how the cache memory is interleaved. Setting: LOI (Default), HOI.
BIOS XOR MB0 Setting: Disabled (Default), Enabled. XOR Bit Select Setting: 18 (Default), 19, 20, 21. Video Memory Size In order to determine how much memory is allocated to the video graphics device. Setting: None, 8M (Default), 16M, 32M, 64M, 128M, 254M. Output display In order to specify the display devices the system is connected to. Setting: Flat Panel, CRT (Default), Panel & CRT. Flat Panel Configuration It allows you to open the Flat Panel Configuration menu.
BIOS 3.6 Integrated Peripherals OnChip IDE Devicev >>> On-Chip IDE Channel 1 The integrated peripheral controller contains an IDE interface with support for two IDE channels. Select Enabled to activate each channel separately. Setting: Disabled, Enabled (Default).
BIOS IDE Primary Master/Slave PIO It allows your system HDD controller to run faster. Rather than having the BIOS issue with a series of commands that transferring to or from the disk drive, PIO (Programmed Input/Output) allows the BIOS to communicate with the controller and CPU directly. When Auto is selected, the BIOS will select the best available mode. Setting: Auto (Default), Mode 0, Mode 1, Mode 2, Mode 3, Mode 4.
BIOS SuperIO Device >>> Onboard FDC Controller Select “Enabled” if you wish to use it. Select “Disabled” if you don’t wish to use it. Setting: Disabled, Enabled (Default). Serial/ Onboard Parallel Port It allows you to select the onboard serial and parallel ports with their addresses. Setting: Serial Port 1 3F8/IRQ4 (Default) Serial Port 2 2F8/IRQ3 (Default) Parallel Port 378H/IRQ7 (Default) UART Mode Select It determines the UART 2 mode in your computer. Setting: IrDA, ASKIR, Normal (Default).
BIOS UR2 Duplex Mode Setting: Full, Half (Default). Use IR Pins Setting: RxD2,TxD2 , IR-Rx2Tx2 (Default). Parallel Port Mode Setting: SPP (Default) EPP ECP ECP+EPP Normal EPP Mode Select Setting: EPP1.9, EPP1.7 (Default) ECP Mode Use DMA Setting: 1, 3 (Default).
BIOS IT8888 ISA Decode IO >>> It allows you to use the IT8888 ISA Decode IO menu to set the IO memory range for the onboard ISA. Decode I/O Space 0/ 1/ 2/ 3/ 4/ 5 It allows you to allocate system resources to the ISA bridge and to enable the function correctly. Setting: Disabled, Enabled (Default). Decode I/O Speed 0/ 1/ 2/ 3/ 4/ 5 It allows you to specify the speed of the ISA bus. Setting: Subtractive Speed, Slow Speed, Medium Speed, Fast Speed.
BIOS Decode I/O Address 0/ 1/ 2/ 3/ 4/ 5 [15:4] It allows you to allocate an address to the ISA bus. The address may range from 0001 to 0FFF. Decode I/O Size 0/ 1/ 2/ 3/ 4/ 5 It allows you to specify the size of the ISA bus. Setting: 1 Byte, 2 Bytes, 4 Bytes, 8 Bytes, 16 Bytes, 32 Bytes, 64 Bytes, 128 Bytes. IT8888 ISA Decode Memory >>> It allows you to use the IT8888 ISA Decode Memory to set the resources for the onboard ISA bus.
BIOS Decode Memory Speed 0/ 1/ 2/ 3 It allows you to specify the memory speed of the ISA bus. Setting: Subtractive Speed, Slow Speed, Medium Speed, Fast Speed. Decode Memory Addr. 0/ 1/ 2/ 3 [23: It allows you to allocate a memory address to the ISA bus. The address may range from 0001 to 0FFF.

BIOS 3.7 PNP/PCI Configurations PNP OS Installed It allows you to enable the PNP OS Install option if it is supported by the OS installed. Setting: No (Default), Yes. Reset Configuration Data It allows you to determine whether to reset the configuration data or not. Setting: Disabled (Default), Enabled. Resources Controlled By This PnP BIOS can configure all of the boot and compatible devices with the use of a PnP operating system. Setting: Auto(ESCD) (Default), Manual.
BIOS IRQ Resources It allows you to configure the IRQ / DMA Resources. Memory Resources It allows you to configure the Memory Resources. PCI/VGA Palette Snoop Some non-standard VGA display cards may not show colors properly. It allows you to set whether or not MPEG ISA/VESA VGA cards can display with PCI/VGA. When “Enabled”, a PCI/VGA can display with an MPEG ISA/VESA VGA card. When “Disabled”, a PCI/VGA can not display with an MPEG ISA/VESA VGA card. Setting: Disabled (Default), Enabled.
BIOS 3.
BIOS 3.9 Load Optimized Defaults It allows you to load the default values to your system configuration. The default setting is optimal and enabled all high performance features.
BIOS 3.10 Set Password Using Password to set a password that will be used exclusively on the system. To specify a password, highlight the type you want and press . The Enter Password: message prompts on the screen. Type the password, up to eight characters in length, and press . And the system confirms your password by asking you to type it again. After setting a password, the screen automatically returns to the main screen.

Appendix 4.5 Watchdog Timer (WDT) Setting WDT is widely used for industry application to monitoring the activity of CPU. Application software depends on its requirement to trigger WDT with adequate timer setting. Before WDT time out, the functional normal system will reload the WDT. The WDT never time out for a normal system. Then, WDT will time out and reset the system automatically to avoid abnormal operation. This board supports 255 levels watchdog timer by software programming.
