BIOS Setup
Introduction
The purpose of this manual is to describe the settings in the Phoenix-Award™
BIOS Setup program on this motherboard. T he Setup program allo ws users to
modify the basic system co nfiguratio n and save these settings to C MOS RAM.
The power of CMOS RAM is supplied b y a battery so that it retains the Setup
info rmat ion when the po wer is turned off.
Basic Inp ut-O utput Sys tem (BIOS) determines what a computer can do without
accessing programs from a disk. This system controls most of the input and
outp ut devices suc h as keyboard, mo use, s erial po rts and disk drives. BIOS
activates at the first stage of the booting process, loading and executing the
operating system. Some additional features, such as virus and password
protection or chipset fine-tuning options are also included in BIOS.
The rest of this manual will to guid e you through the options and settings in
BIOS Setup.
Plug and Pla y Support

video monito rs can also be managed by this PHOENIX-AWARD BIOS.
ACPI Support
Phoenix-Award ACPI BIOS support Version 1.0b of Advanc ed Configuration
and Power interfac e specification (ACPI). It provides ASL code for power
management and device configuration capabilit ies as defined in the ACPI
specification, developed by Microsoft, Intel and Toshiba.

7 PnP/PCI Configurations
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 compo nents. This sectio n covers some very tec hnical items and it is
strongly recommended that only experienced us ers sho uld make any changes to
the default settings.

Reset Configuration Data
The s ystem BI OS supports the PnP feature whic h req uires the system to record
whic h reso urces are as s igned and pro tects reso urces fro m co nflic t.
Every per ipheral devic e has a node, whic h is c alled ESCD. This nod e records
whic h resourc es ar e ass igned to it. The s ystem needs to record and updat e ESCD
to the memory locations. T hese locations are reserved in the sys tem BIOS. If the
Disabled (default) option is chos en, the system‘s ESCD will update only when
the new co nfiguration varies fro m the last one. If t he Enabled optio n is chos en,
the system is forc ed to update ESCDs and then is auto matically set to the
“Disabled ” mode.
The above settings will be shown on the screen o nly if “Manual” is chosen for
the res ourc es contro lled b y funct ion.
Legac y is the term, which signif ies that a resourc e is assigned to the IS A Bus
and p rovides non-P nP ISA add -on cards. PC I / IS A PnP s ignify that a r eso urce

peripherals.
The Choices: Disabled (def ault), Enabled.
Resources Controlled By
By Choos ing “Auto(ESCD)” (default), the system BIOS will detect the 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.
The Choices: Auto (ESCD) (default), Manual.

Special Notice:
If the syst em’s freq uenc y that you are s elected is not funct io ning, there are two methods
of booting-up the system.
Method 1:
Clear the CMOS d ata by s etting the JCMOS 1 ((2-3) clos ed)) as “ON” status. All the
CMOS d ata will be loaded as d efaults setting.
Method 2:
Press the <Ins ert> key a nd Power b utton simultaneous ly, after that keep -on press ing the
<Insert> key until the po wer-on screen showed.
This action will boot-up the system according to FSB of the processor
It’s strongly reco mmended to set CPU Vcore and clock in default setting. If the CPU
Vcore and clock are not in default setting, it may cause CPU or M/B damage.
