BIOS Setup
Introduction
T his manu al discussed Aw ard™ Set up pr ogra m bu ilt into the ROM BI OS . The Setup
program allows users to modify the basic system configuration. This special information is
th en stored in ba tt ery-bac ke d RAM s o that it retain s t he Setup info rmation w hen the po wer
is turned off.
T he Award BIO S™ installed in you r comput er system’s ROM (Re ad O nly Mem ory) is a
custom version of an industry standard BIOS. This means that it supports Intel Pentium
processor input/output system. The BIOS provides critical low-level support for standard
devices such as disk drives and serial and parallel ports.
Adding important has customized the Award BIOS™, but nonstandard, features such as
virus and password protection as well as special support for detailed fine-tuning of the
chipset controlling the entire system.
The rest of this manual is intended to guide you through the process of configuring your
system using Setup.
Plug and Play Support
These AWARD BIOS supports the Plug and P lay Version 1.0A specification. ESCD
(Extended System Configuration Data) write is supported.
EPA Gree n PC Support
This AWARD BIOS supports Version 1.03 of the EPA Green PC specification.
APM Support
These AWARD BIOS supports Version 1.1&1.2 of the Advanced Power Management
(APM) specification. Power management features are imp lemented via the System
Management Interrupt (SMI). Sleep and Suspend power management modes are supported.
Power to the hard disk drives and video monitors can be managed by this AWARD BIOS.
ACPI Support
Award ACPI BIOS support Version 1.0 of Advanced Configuration and Power interface
specif ication (ACPI). It provides ASL code for power management and device
configuration capabilities as defined in the ACPI specification, developed by Microsoft,
Intel and Toshiba.

system will need AGP driver to initialize the card . So , if the AGP driver of the VGA card
does not support the init ialization feature , the display may work abnormally or not function
after S3 .
The Choices:Aut o , Yes (default), No.
Ac Loss Auto Restart
This field determines the action the system will automatically take when power is restored
to a system that had lost power previously w ithout any subsequent manual intervention.
There are 3 sources that provide current to the CMOS area that retains these Power-On
instructions; the motherboard battery (3V), the P ower Supply (5VSB), and the Power
Supply (3.3V). While AC is not supplying power, the motherboard uses the motherboard
battery (3V). If AC power is supplied and the Power Supply is not turned on, 5VSB from
the Power Supply is used. When the Power Supply is eventually turned on 3.3V from the
Power Supply will be used.There are 3 options: “Former-Sts”, “On”, “Off”.
“Off” (default) Means always set CMOS to the “Off” status when AC power is lost.
“On” Means always set CMOS to the “On” status when AC power is lost
“Former-Sts” Means to maintain the last status of the CMOS when AC power is lost.
For example: If set to “Former-Sts” and AC power is lost when system is live, then after
AC power is restored, the system will automatically power on. If AC power is lost when
system is not live, system will remain powered off.

IRQs Activity Monitoring
P ress Enter to access another sub menu used to configure the different wake up events (i.e.
wake on LPT & COMM activity).
This section describes configuring the PCI bus system. PCI, or Personal Computer
Interconnect, is a system which allows I/O devices to operate at speeds nearing the speed of
the CPU itself uses when communicating with its own spec ial components. This section
covers some very technical items and it is strongly recommended that only experienced
users should make any changes to the default settings.
Figure 7. PnP/PCI Configurations
PNP O S Ins tal le d
When set to YES, BIOS will only initialize the PnP cards used for the boot sequence
(VG A, I DE, SCSI). The rest of the ca rds will be init ia lized by the PnP o perating
system like Window™ 95. When set to NO, BIOS will initialize all the PnP cards. For
non-PnP operating systems (DOS, Netware™), this option must set to NO.
The Choices : No (default), Yes.
Reset Config uration Data
The system BIOS supports the PnP feature which requires the system to record which
resources are assigned and protects resources from conflict. Every peripheral device has a
node, which is called ESCD. This node records which resources are assigned to it. The
system n eed s t o re cor d an d update ESCD to the mem ory loca tio ns. Th ese lo cat ions (4K)
are reserved in the system BIOS. If the Disabled (default) option is chosen, the system‘s
ESCD will update only when the new configurat ion varies from the last one. If the Enabled
option is chosen, the system is forced to update ESCDs and then is automatically set to the
“D isabled” mode.
The above settings will be shown on the screen only if “Manual” is chosen for the resources
controlled by function.

non-PnP ISA add-on cards. PCI / ISA PnP signifies that a resource is assigned to the PCI
Bus or provides for ISA PnP add-on cards and peripherals.
The Choices: Disabled (default), Enabled.
Resource s Controlled B y
By Choosing “Auto(ESCD)” (default), the system BIOS will detect the system resources
and automatically assign the relative IRQ and DMA channel for each peripheral.By
Choosin g “Manual”, the user will need to assign IRQ & DMA for add-on cards. Be sure
that there are no IRQ/DMA and I/O port conflicts.
IRQ Resources
This submenu will allow you to assign each system interrupt a type, depending on the type
of device using the interrupt. When you press the “Press Enter” tag, you will be directed to
a submenu that will allow you to configure the system interrupts. This is only
configurable when “Resources Controlled By” is set to “Manual”.
IRQ-3 assigned to PCI Device
IRQ-4 assigned to PCI Device
IRQ-5 assigned to PCI Device
IRQ-7 assigned to PCI Device

PCI / VG A Palette Snoop
Choose Disabled or Enabled. Some graphic controllers wh ich are not VGA compatible
take the output from a VGA controller and map it to their display as a way to provide boot
information and VGA compatibility.
However, the color information coming from the VGA contro ller is drawn from the palette
table ins ide the VGA controller to generate the proper colors, and the graphic controller
needs to know what is in the pa lette of the VGA con troller. T o do this, the non-VGA
graphic controller watches for the Write access to the VGA palette and registers the snoop
data. In PCI based systems, where the VGA controller is on the P CI bus and a non-VGA
graphic controller is on an ISA bus, the Write Access to the palette will not show up on the
ISA bus if the PCI VGA controller responds to the Write
In this case, the P CI VGA controller shou ld not respond to the Write, it should on ly snoop
the data and permit the access to be forwarded to the ISA bus. The non-VGA ISA graphic
controller can then snoop the data on the ISA bus. Unless you have the above situation,
you should disable this option.
