BIOS Setup

Introduction

T his manual discuss ed Award™ Setup pr ogram built into th e ROM BIOS. T he Setup
program allows users to modify the basic system configuration. This special information is
th en st ored in battery-backed RAM so th at it retain s the S etup information wh en th e power
is turned off.

T he Award B IOS™ ins talled in your comp uter system’s RO M (R ead O nly Memor y) is a
custom version of an industry standard BIOS. This means that it supports Nvidia CK8

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 specificat ion.

APM Support

These AWARD BIOS supports Version 1.1&1.2 of the Advanced Power Management
(APM) specification. Power management features are implemented via the System

Management Interrupt (SMI). Sleep and Suspend power management modes are supported.
This AWARD BIOS can manage power to the hard disk drives and video monitors .

ACPI Support

Award ACPI BIOS support Version 1.0 of Advanced Configurat ion 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.

There are 3 sources that provide current to the CMOS area that retains these P ower-On
instruct ions; the motherboard battery (3 V), 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 automatica lly power on. If AC power is lost when

system is not live, system will remain powered off.

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 special 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.

Reset Configuration Da ta

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. T his node records which resources are assigned to it. The
syst em needs to recor d and upd ate ESCD to the memory lo cations. T h ese locations ( 4K)
are reserved in the system BIOS. If the Disabled (default) option is chosen, the system‘s
ESCD will update only when the new configuration var ies 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 isab led” m od e.
The above settings will be shown on the screen only if “Manual” is chosen for the resources
controlled by function.
Le gacy is the term, which signif ies th at a resour ce is as signed to the ISA Bus and pro vides
non-PnP ISA add-on cards. PCI / ISA PnP signifies that a resource is assigned to the P CI
Bus or provides for ISA PnP add-on cards and peripherals.
The Choices: Disabled (default), Enabled.

Resources 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
IRQ-9 assigned to PCI Device
IRQ-10 assigned to PCI Device
IRQ-11 assigned to PCI Device
IRQ-12 assigned to PCI Device
IRQ-14 assigned to PCI Device
IRQ-15 assigned to PCI Device

PCI / VG A Pa le tte Snoop

Choose Disabled or Enabled. Some graphic controllers which 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 f rom the palette
table ins ide the VGA controller to generate the proper colors, and the graphic controller

needs to know what is in the palette of the VGA controller. 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 c ase, the PCI VGA controller should not res po nd t o the Write, it should only 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 disab le this option.

Disabled(default) Disables the function.
Enabled Enables the function.

This item allows you to select DDR Voltage Control.
The Choices: Default (Default), 2.75V, 2.85V, 2.90V.

If unfortunately, the system’s frequency that you are selected is
not functioning, there are two methods of booting-up the system.

Method 1: Clear the CMOS data by setting the JCMOS1 ((2-3) closed)) as
“ON” status. All the CMOS data will be loaded as defaults setting.

Method 2: Press the <Insert> key and Power button simultaneously, after that
keep-on pressing the <Insert> key until the power-on screen showed. This
action will boot-up the system according to FSB of the processor.
