BIOS Setup

Introduction

This manual discussed Award™ Setup program built into the ROM BIOS. The Setup
program allows u sers to modify t he b asic syst em con figuration . Th is speci al infor mation i s
then stored in battery-backed RAM so that it retains the Setup information when the power
is turned off.

The Award BIO S™ installed in your computer syst em’s ROM (Read Only M emory) 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 suc h as dis k dri v e s a nd serial and parall e l po r ts .

Adding important has customized th e Award BIOS™, but nonstandard, features s uch as
virus and pas sword protection as w ell as special suppor t for detailed fine-tunin g 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 Play Version 1.0A specification. ESCD
(Extended Sys te m Configura t ion Da t a) wr it e is s upport ed.

EPA Green PC Support

This AWARD BIOS supports Version 1.03 of the EPA Green PC specification.

APM Support

7 PnP/PCI Configurations

This section describes configuring the PCI bus system. PCI, or Personal Computer
Interconnect, is a system which allows I/O devic es 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.



Figure 7. PnP/PCI Configuration s

Reset Configuration 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 i s call ed E SCD. This node recor ds w hich resou rces ar e assign ed to it. The
system needs to record and update ESCD to the memory locations. These locations (4K)
are reserved in the system BIOS. If the Disabled (d efault) option is ch osen, the system‘s
ESCD will update only wh en the n ew confi gurat ion varies from the last one. If the Enabl ed
option is chosen, th e syst em is forc ed to up date ESCDs and then is auto matically s et to th e
“Disabled” mode.

The above settings will be shown on the screen only if “Manual” is chosen for the resources
controlle d by func tio n.
Legacy is the term, which signifies that a resource is assigned to the ISA Bus and provides
non-PnP ISA add-on cards. PCI / ISA PnP signifies that a resource is assigned to the PCI

The Choices: Disabled (default), Enabled.

Resources Controlled By

By Choosing “Auto(ESCD)” (default), the system BIOS wil l detect th e system resources
and automatically assign the relative IRQ and DMA channel for each peripheral.By
Choosing “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.

of device using the interru p t. When you press the “Press Enter” tag, you w ill 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”.

PCI / VGA Palette Snoop

Choose Disabl ed or Enabled. S ome graphic controll ers 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 compat ibility.

However, the color inf ormation comin g from the VGA controll er is draw n from the p alette
table inside the VGA controll er to generate th e proper colors, an d the graphic con troller
needs to know what is in the palette of the VGA controller. To do this, the non-VGA
graphic controller watches for the Write access to the VGA palette and registers the snoop
data. In PCI based syst ems, wh ere th e VGA control ler is on th e PCI b us 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, th e PCI VGA con troll er should not respon d to the Writ e, 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 da ta on the ISA bus. Unless you have the above situation,
you should disable this option.

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

The Choices: Enabled (default), Disabled.

CPU Frequency

This item allows you to control CPU Frequency.

The Choices: Default (default), 100MHz, 133MHz.

DRAM Frequency

This item allows you to control DRAM Frequency.
The Choices: By SPD (default) , 200MH z, 266M Hz, 333M Hz.

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