PNP/PCI CONFIGURATION
AWARD SOFTWARE, INC.
3.6.1 PNP OS Installed
This field allows you to use a Plug-and-Play (PnP) operating system.
Please set it as No if the operating system has no PnP function or to avoid reassigning the IRQs by
the operating system.
3.6.2 Resources Controlled By
Default setting is "Auto". This setting allows the BIOS to self detect setting and Plug-and-Play devices
during start up. The user can select and configure IRQs under "Manual" mode.
3.6.3 Reset Configuration Data
In case a conflict occurs after you assign the IRQs or after you configure your system, you can enable this
function to allow your system to automatically reset your configuration and reassign the IRQs, DMAs, and
I/O address.
3.6.4 IRQ-xx assigned to
If your ISA card is not PnP compatible and requires a special IRQ to support its function, set the selected
IRQ-x assigned to :Legacy ISA. This setting informs the PnP BIOS to reserve the selected IRQ for the
installed legacy ISA card.
3.6.5 DMA-x assigned to
If your ISA card is not PnP compatible and requires a special DMA channel to support its function, set the
selected DMA channel to Legacy ISA. This setting informs the PnP BIOS to reserve the selected DMA
channel for the installed legacy ISA card.
3.6.6 CPU to PCI Write Buffer
When enabled, up to four D words of data can be written to the PCI bus without interrupting the CPU.
When disabled, a write buffer is not used and the CPU read cycle will not be completed until the PCI bus
signals that it is ready to receive the data.
3.6.7 PCI Dynamic Bursting
When enabled, data transfer on the PCI bus, where possible, make use of the high-performance PCI bust
protocol, in which greater amounts of data are transferred at a single command.
3.6.8 PCI Master 0 WS Write

When enabled, writes to the PCI bus are command with zero wait states.
3.6.9 PCI Delay Transaction
The chipset has an embedded 32-bit posted write buffer to support delay transactions cycles. Select
Enabled to support compliance with PCI specification version 2.1.
3.6.10 PCI # 2 Access # 1 Retry
This item allows you enabled/disabled the PCI # 2 Access # 1 Retry.
3.6.11 AGP Master 1 WS Write
This implements a single delay when writing to the PCI Bus. By default, two-wait states are used by the
system, allowing for greater stability.
3.6.12 AGP Master 1 WS Read
This implements a single delay when reading to the PCI Bus. By default, two-wait states are used by the
system, allowing for greater stability.
3.6.13 PCI IRQ Actived By
This sets the method by which the PCI bus recognizes that an IRQ service is being requested by a device.
Under all circumstances, you should retain the default configuration unless advised otherwise by your
system manufacturer. The choices are Level (default) and Edge.
3.6.14 Assign IRQ For USB
When Enabled, the system automatically assigns an IRQ for the USB device connected to your system.
However, if you are not using USB devices and an ISA slot required an IRQ address, set this function to
Disabled. The IRQ address previously occupied by the USB device will be available for the ISA slot.
3.6.15 Assign IRQ For VGA
The Enabled option allows the BIOS to auto-route an IRQ for use by a VGA card. While most of the VGA
cards do not need the IRQ assignment, certain VGA cards may need it.

INTEGRATED PERIPHERALS
AWARD SOFTWARE, INC.
3.7.1 OnChip IDE Channel 0/1
Select "Enabled" to activate each on-board IDE channel separately, Select "Disabled", if you install an add-
on IDE Control card

3.7.2 IDE Prefetch Mode
Enable prefetching for IDE drive interfaces that support its faster drive accesses. If you are getting disk
drive errors, change the setting to omit the drive interface where the errors occur. Depending on the
configuration of your IDE subsystem, this field may not appear, and it does appear when the Internal
PCI/IDE filed, above, is Disabled.
3.7.3 IDE HDD Block Mode
This feature enhances disk performance by allowing multi-sector data transfers and eliminates the
interrupt handling time for each sector.
3.7.4 Primary & Secondary Master/Slave PIO
These four PIO fields let you set a PIO mode (0-4) for each of four IDE devices. When under "Auto" mode,
the system automatically set the best mode for each device
3.7.5 Primary & Secondary Master/Slave UDMA
When set to "Auto" mode, the system will detect if the hard drive supports Ultra DMA mode.
3.7.6 Init Display First
Select AGP or PCI Slot for system to detect first when boot-up.
3.7.7 Onboard FDC Controller
Select "Enabled" to activate the on-board FDC
Select "Disabled" to activate an add-on FDC
3.7.8 Onboard UART Port 1 & 2
Select an address and corresponding interrupt for the first/second serial port. The default value for the
first serial port is "3F8/IRQ4" and the second serial port is "2F8/IRQ3".
3.7.9 UART2 Mode
Select to activate the Infrared transfer function.
3.7.10 Onboard Parallel Port
Select address and interrupt for the Parallel port.
3.7.11 Parallel Port Mode

If your system has an IDE hard drive, you can use this function to detect its parameters and enter
them into the Standard CMOS Setup automatically.
This routine only detects one set of parameters. If your hard disk is formatted using different
parameters than those detected, you have to enter the parameters manually. If the parameters listed
do not match the ones used to format the disk, the information on that disk will not be accessible. If
the auto-detected parameters displayed do not match those that are used for your drive, ignore
them. Type N to reject the values and enter the correct ones manually from the Standard CMOS
Setup screen.
