Clear CMOS Jumper: JBAT1
There is a CMOS RAM onboard that has a power supply from an external battery to
keep the data of system configuration. With the CMOS RAM, the system can auto-
matically boot OS every time it is turned on. If you want to clear the system configuration,
set the jumper to clear data.Important
You can clear CMOS by shorting 2-3 pin while the system is off. Then return
to 1-2 pin position. Avoid clearing the CMOS while the system is on; it will
damage the mainboard.JBAT1

ATi CrossFire (Multi-GPU) Technology
ATi CrossFire (Multi-GPU) technology is an exciting new technology developed by ATI
that allows the power of multiple Graphics. CrossFire requires a CrossFire Edition
graphics card and a compatible standard Radeon (CrossFire Ready) graphics card
from the same series. To utilize this technology, always install the CrossFire Edition
graphics card in the Master PCIE 2.0X16 (PCI_EX1) slot and install the CrossFire
Ready graphics card in the Slave PCIE 2.0X16 (PCI_EX2) slot. The mainboard can
auto detect the CrossFire mode by software, therefore you don’t have to enable the
CrossFire in BIOS by yourself. Following the process below to complete CrossFire:
1. Install the CrossFire Edition graphics card in the Master PCIEX16 (PCI_EX1) slot
and install the CrossFire Ready graphics card in the Slave PCIEX16 (PCI_EX2)
slot.
2. With two cards installed, an Cross Fire Video Link cable is required to connect the
golden fingers on the top of these two graphics cards (refer to the picture below).
Please note that although you have installed two graphics cards, only the video
outputs on the CrossFire Edition graphics card will work. Hence, you only need to
connect a monitor to the CrossFire Edition graphics card.Important
1. Mainboard photos shown in this section are for demonstration only. The
appearance of your mainboard may vary depending on the model you purchase.
2. If you intend to install TWO graphics cards for CrossFire mode, make sure
that:
   a. these two graphics cards are of the same brand and specifications;
   b. these two PCIE x16 lanes will auto arrange from x16/ x0 to x8/ x8
3. If you intend to install only ONE graphics card, make sure that:
a. the graphics card is Installed on the mazarine PCIE x16 slot (PCI_EX1);
4. Only Windows®
 XP with Service Pack 2 (SP2)& Windows®
 XP Profes
    -sional x64 Edition & Windows®
  Vista support the CrossFire function.CrossFire Video Link cable 
						

							2-21Hardware Setup3.When all of the hardware and software has been properly set up and installed,
reboot the system. After entering the O.S., click the “Catalyst™ Control Center”
icon      on the desktop. There is a setting in the Catalyst™ Control Center that needs
to be enabled for CrossFire™ to operate. The following aspect appears in Catalyst™
Control Center:Important
A CrossFireX™ system has four possible display modes:
• SuperTiling
• Scissor Mode
• Alternate Frame Rendering
• Super Anti-aliasing.

The PCI slot supports LAN card, SCSI card, USB card, and other add-on cards that
comply with PCI specifications.
PCI Interrupt Request Routing
The IRQ, acronym of interrupt request line and pronounced I-R-Q, are hardware lines
over which devices can send interrupt signals to the microprocessor. The PCI IRQ
pins are typically connected to the PCI bus pins as follows:Order 1Order 2Order 3Order 4
PCI Slot 1INT A#INT B#INT C#INT D#
PCI Slot 2INT B#INT C#INT D#INT A#Important
When adding or removing expansion cards, make sure that you unplug the
power supply first. Meanwhile, read the documentation for the expansion
card to configure any necessary hardware or software settings for the expan-
sion card, such as jumpers, switches or BIOS configuration.

BIOS Setup
This chapter provides information on the BIOS Setup
program and allows you to configure  the system for
optimum use.
You may need to run the Setup program when:

3-2Entering SetupImportant
1.The items under each BIOS category described in this chapter are under
continuous update for better system performance. Therefore, the descrip-
tion may be slightly different from the latest BIOS and should be held for
reference only.
2.Upon boot-up, the 1st line appearing after the memory count is the BIOS
version. It is usually in the format:
A7388AMS V1.0 083007 where:
1st digit refers to BIOS maker as A = AMI, W = AWARD, and P =
PHOENIX.
2nd - 5th digit refers to the model number.
6th digit refers to the chipset as I = Intel, N = nVidia, A = AMD and
V = VIA.
7th - 8th digit refers to the customer as MS = all standard customers.
V1.0 refers to the BIOS version.
083007 refers to the date this BIOS was released. Power on the computer and the system will start POST (Power On Self Test) process.
When the message below appears on the screen, press  key to enter Setup.
Press DEL to enter SETUP
If the message disappears before you respond and you still wish to enter Setup,
restart the system by turning it OFF and On or pressing the RESET button. You may
also restart the system by simultaneously pressing , , and  keys.
