CHAPTER 5: WARPSPEEDER™

5.1 INTRODUCTION

[WarpSpeeder™], a new powerful control utility, features three
user-friendly functions including Overclock Manager, Overvoltage
Manager, and Hardware Monitor.

With the Overclock Manager, users can easily 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
voltage and Memory voltage. The cool Hardware Monitor smartly indicates
the temperatures, voltage and CPU fan speed as well 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
shown on our main panel.

Moreover, to protect users' computer systems if the setting is not
appropriate when testing and results in system fail or hang,
[WarpSpeeder™] technology assures the system stability by automatically
rebooting the computer and then restart to a speed that is either the
original system speed or a suitable one.

5.2 SYSTEM REQUIREMENT

OS Support: Windows 98 SE, Windows Me, Windows 2000, Windows XP
DirectX: DirectX 8.1 or above. (The Windows XP operating system

includes DirectX 8.1. If you use Windows XP, you do not need to install

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.

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.

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”.

PCI / VGA Palette 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 controller is drawn from the palette
table inside the VGA controller to generate the proper colors, and the graphic controller
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 systems, where the VGA controller is on the PCI 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 case, the PCI VGA controller should not respond to 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 disable this option.

Assign IRQ For USB

This item allows the users to choose which IRQ to assign for the USB.

IRQ-3 assigned to PCI Device
IRQ-4 assigned to PCI Device

This item allows you to enable / disable auto Detect PCI Clock.
The Choices: Enabled (default), Disabled.

This item allows you to select CPU Clock, and CPU over clocking.
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 COMS data by setting the JCOMS1 ((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.

It’s strongly recommended 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.
