BIOS Setup
Introduction
The purpose of this manual is to describe the settings in the Phoenix-Award™
BIOS Setup program on this motherboard. The Setup program allows users to
mod ify the bas ic s ystem configuration and save these settings to CMOS RAM.
The power of CMOS RAM is supplied by a battery so that it retains the Setup
info rmation when the po wer is t urned off.
Basic Input-Output System (BIOS) determines what a computer can do without
access ing programs from a disk. This system controls most of the input and
outp ut dev ices such as k eyboard, mouse, s erial po rts and dis k drives. BIOS
activates at the firs t stag e of the booting proc ess, 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 guide you through the options and settings in
BIOS Setup.

whic h reso urces ar e ass igned and protects reso urces from conflict.
Every per ipheral d evice has a node, whic h is called ESCD. This node records
whic h resourc es are ass igned to it. T he sys tem needs to record a nd update ESCD
to the memory locat ions. These locations are reserved in the system BIOS. If t he
Disabled (default) option is chosen, the system‘s ESCD will update only when
the ne w co nfigurat ion varies from the last one. If the Enabled opt ion is c hos en,
the system is fo rced to update ESCDs and then is automatically set to the
“Disabled” mode.
The above settings will be shown on the screen only if “Manual” is chosen for
the resources cont ro lled by function.
Legac y is the term, whic h signifies that a resource is ass igned to the ISA Bus
and provides non-PnP ISA add-on c ards. PCI / ISA PnP signify that a resource
is assigned to the PCI Bus or provides for ISA PnP add-on cards and
peripherals.
The Choices: Disabled (default), 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 ue nc y that you are selected is not func tioning, there are two
methods of booting-up the system.
Method 1:
Clear the C OMS data b y sett ing the JCOMS1 ((2-3) closed)) as “ON” st atus. 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
It’s strongly recommended to set CPU Vcore and clock in default setting. If the
CPU Vcore and clock are no t in default setting, it may cause CPU or M/B
damage.
