CHAPTER 5: WARPSPEEDER™
5.1 INTRODUCTION
[WarpSpeeder™], a new powerful control utility, features three
user-friendly functions including Overclock Manager, Overvol tage
Manager, and Hardware Monitor.
With the Overclock M anager, 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
vol tage and Me mor y volta ge. The co o l Har dw are Mo ni tor s mar t ly in d icates
the tem peratures, vol tage and CPU fan speed as well as the chi pset
information. Also, in the About panel, you can get detail descri ptions 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 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 com puter and then restart to a speed that is ei ther the
original system speed or a suitable one.

Note:
Because the overclock, overvol tage, and hardware monitor features
are controlled by several separate chipset, [WarpSpeeder™] divide
these features to separate panels. If one chipset is not on board, the

7 PnP/PCI Configurations
This section describes configuring the PCI bus system. PCI, or Personal Computer
Interconnect, is a system whi ch allows I/O devices to op erate 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 Configurations
Init Display First
The option let you select the initial display slot.
The Choices: PCI Slot (default), AGP .
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 updat e ESCD to the memory
locations. These locations are reserv ed i n the s ystem 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

The Choices: Disabled (default), Enabled.
Resources Con trolled 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 Res ou rces
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”.

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, th e Write A ccess to th e palette will not show up on the
ISA bus if the PCI VGA controller responds to the Write.
In th is cas e, t h e P CI VG A control l er sh ou ld n o t re sp on d to t h e W rit 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 data on the ISA bus. Unless you have the above situation,
you should disable this option.
