CHAPTER 4: NVIDIA RAID FUNCTIONS
4.1 OPERATION SYSTEM
z Support s Windows XP H om e/Prof essional Edition, and W indows 2000 Prof essional.
4.2 RAID ARRAYS
NVRAID suppor ts the following type s of RAID arra ys:
RAID 0: RAID 0 defines a disk striping scheme that improves disk read and write times for
many applications.
RAID 1: RAID 1 defines techniques for mirrori ng data.
RAID 0+1: RAID 0+1 combines the techniques used in RAID 0 and RAID 1.
4.3 HOW RAIDWORKS
RAID 0:
The controller “ stripes” data across multiple drives in a RAID 0 array system. It breaks
up a large file into smaller blocks and performs disk reads and writes across multiple
drives in parallel. The size of each block is determined by the stripe size parameter,
which you set during the creation of the RAID set based on the system environment. This
technique reduces overall disk access time and offers h igh bandwidth .
Fea tures and Be nefits
Drives: Minimum 1, and m ax imum is up to 6 or 8. Depending on the
platform.
Uses: I ntended for non-crit ical data requiring high dat a throughput, or any
environment that does not require fault tolerance.
Benefits: provides increas ed dat a throughput, espec ially for large files. No
capac ity loss penalty f or parity.
Drawbacks: Does not deliver any fault toleranc e. If any drive in the array
fails, all data is lost.
Faul t Tolerance : No.

Bl o ck 5
Bl o ck 2
B lock 4
B lock 6
Page 23
NF4 A M2 / NF4 4X AM2
RAID 1:
Every read and write is actually carried out in parallel across 2 disk drives in a RAID 1
array system. The mirrored (backup) copy of the data can reside on the same disk or on
a second redundant drive in the array. RAID 1 provides a hot-standby copy of data if
the active volume or d rive i s corrupted o r becomes unavailable because of a hardw are
failure.
RAID techniques can be applied for high-availability solutions, or as a form of
automatic backup that eliminates tedious manual backups to more expensive and less
reliable media.
Fea tures and Be nefits
Drives: Minimum 2, and max imum is 2.
Uses: RAID 1 is ideal f or small dat abas es or any other applicat ion t hat
requires f ault tolerance and minimal capaci t y.
Benefits: Provides 100% data redundancy. Should one drive f ail, the
controller switches to the other dri ve.
Drawbacks: Requires 2 drives for the st orage space of one drive.
Performanc e is impaired during drive rebuilds.
Fault To le rance : Yes.

Motherboard Manual
RAID 0+1:
RAID 0 drives can be mirrored using RAID 1 techniques. Resulting in a RAID 0+1
solution for improved performance plus resiliency.
Fea tures and Be nefits
- Drives: Minimum 4, and m ax imum is 6 or 8, depending on t he platform.
- Benefits: Optimizes for both fault tolerance and performanc e, allowing f or
autom at ic redundancy. May be simultaneously used with other RAI D
levels in an array, and allows for spare disks.
- Drawbacks: Requires twice the available dis k s pac e f or data redundancy,
the same as RAID level 1.

CHAPTER 6: WARPSPEED ER™
6.1 INTRODUCTION
[WarpSpeeder™], a new powerful control utility, features three
user-friendly functions including Overclock M anager, Overvol tage
Manager, and Hardware Monitor.
With the Overclock Manager, users can easi ly adjust the frequency they
prefer or they can get the best CPU performance with just one click. The
Overvoltage Manager, on the other hand, helps to power up CPU core
vol tage and Me mor y v ol tage. The co o l Har dw are Mo ni tor smar t ly in dicates
the tem peratures, vol tage and CPU fan speed as wel l as the chipset
information. Also, in the About panel, you can get detail descriptions about
BIOS model and chipsets. In addition, the frequency status of CPU,
memory, AGP and PCI along with the CPU speed are synchronically
s how n on our ma i n p an el .
Moreover, to protect users' computer systems i f the setting i s not
appropriate when testing and results in system fail or hang,
[WarpSpeeder™] technol ogy assures the system stability by autom atically
rebooting the computer and then restart to a speed that is either the
original system speed or a suitable one.
6.2 SYSTEM REQU IREMENT
OS Support: Windows 98 SE, Windows Me, Windows 2000, Windows XP
DirectX: DirectX 8.1 or above. (The Wi ndows XP operating system
includes DirectX 8.1. If you use Windows XP, you do not need to instal l
Dir ec tX 8.1.)

[Wa rpS pee de r™ ] will set th e be st and sta ble pe rformance an d
frequency automati cally. [WarpSpeeder™] utility will execute a
se ries of testing un til system f ail. Th en system will do fa il-safe
reboot by using Watchdog functi on. After reboot, the
[WarpSpeeder™] utility will restore to the hardware default
setting or load the verified best and stable frequency according
to the Recovery Dialog’s setting.
d. “Verify button”: User can click this button and [WarpSpeeder™]
will proceed a testing for current frequency. If the testing is ok,
then the current fre q uency will be saved into syste m regi stry. If
the testing fail, system will do a fail-safe rebooti ng. After reboot,
the [WarpSpe ed er™] utility will restore to the ha rdware default
setting or load the verified best and stable frequency according
to the Recovery Dialog’s setting.
Note:
Becaus e the testing programs, invok ed in Aut o-ov erc loc k and Verify,
include D irectDraw, Direct3D and DirectShow tests, the Direc t X 8. 1 or
newer runtime library is required. And please m ak e s ure your display
card’s color depth is High color (16 bit ) or True color( 24/ 32 bit ) that is
required for Direct3D rendering.
5. Hardware Monitor Panel

of all the chipset that are related to overclocking. You can also get
the mainboard’s BIOS model and the Version number of
[WarpSpeeder™] utility.
34
Note :
Because the overclock, overvoltage, and hardware monitor features
are controlled by several separate chipset, [WarpSpeeder™] divide
these features to separate panel s. If one chipset is not on board, the
correlative but ton i n Main panel will be disabled, but will not inter fere
other panels’ functions. This property can make [WarpSpeeder™]
utility more robust.

BIOS Setup
Introduction
The purpose of this manual is to describe the settings in the Award™ BIOS
Setup program on this motherboard. The Setup program allows users to modify
the basic system configuration and save these settings to CMOS RAM. The
power of CMOS RAM is supplied by a battery so that it retains the Setup
information when the power is turned off.
Basic Input-Output System (BIOS) determines what a computer can do without
accessing programs from a disk. This system controls most of the input and
output devices such as keyboard, mouse, serial ports 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 guide you through the options and settings in
BIOS Setup.

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 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.

Init Display First
This item allows you to decide to active whether PCI Slot or on-chip VGA first.
The Choices: PCEx, PCI Slot (default).

Page 87
NF4 AM2
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 is called ESCD. This node records
which resources are assigned to it. The system needs to record and update ESCD
to the memory locations. These locations are reserved in the system BIOS. If the
Disabled (default) option is chosen, the system‘s ESCD will update only when
the new configuration 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
“Disabled” mode.
The above settings will be shown on the screen only if “Manual” is chosen for
the resources controlled by function.
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 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 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 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.
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”.
