Expansion slots  
In the future, you may need to install expansion cards. The following sub-sections describe  
the slots and the expansion cards that they support.  
Unplug the power cord before adding or removing expansion cards. Failure to do so may  
cause you physical injury and damage motherboard components.  
1.8.1  
Installing an expansion card  
To install an expansion card:  
1.  
Before installing the expansion card, read the documentation that came with it and  
make the necessary hardware settings for the card.  
2.  
3.  
Remove the system unit cover (if your motherboard is already installed in a chassis).  
Remove the bracket opposite the slot that you intend to use. Keep the screw for later  
use.  
4.  
Align the card connector with the slot and press firmly until the card is completely  
seated on the slot.  
5.  
6.  
Secure the card to the chassis with the screw you removed earlier.  
Replace the system cover.  
1.8.2  
Configuring an expansion card  
After installing the expansion card, configure it by adjusting the software settings.  
1.  
Turn on the system and change the necessary BIOS settings, if any. See Chapter 2 for  
information on BIOS setup.  
2.  
3.  
Assign an IRQ to the card.  
Install the software drivers for the expansion card.  
When using PCI cards on shared slots, ensure that the drivers support “Share IRQ” or that  
the cards do not need IRQ assignments. Otherwise, conflicts will arise between the two PCI  
groups, making the system unstable and the card inoperable.  
1.8.3  
PCI slots  
The PCI slots support cards such as a LAN card, SCSI card, USB card, and other cards that  
comply with PCI specifications.  
1.8.4  
PCI Express x1 slots  
This motherboard supports PCI Express x1 network cards, SCSI cards, and other cards that  
comply with the PCI Express specifications.  
1.8.5  
PCI Express x16 slot  
This motherboard supports a PCI Express x16 graphics card that complies with the PCI  
Express specifications.

Jumpers  
1.  
Clear RTC RAM (3-pin CLRTC)  
This jumper allows you to clear the Real Time Clock (RTC) RAM in CMOS. You can  
clear the CMOS memory of date, time, and system setup parameters by erasing  
the CMOS RTC RAM data. The onboard button cell battery powers the RAM data in  
CMOS, which include system setup information such as system passwords.  
CLRTC

P5QL-CM  
Normal  
Clear RTC  
(Default)  
P5QL-CM Clear RTC RAM  
To erase the RTC RAM:  
1. Turn OFF the computer and unplug the power cord.  
2. Move the jumper cap from pins 1-2 (default) to pins 2-3. Keep the cap on pins 2-3  
for about 5-10 seconds, then move the cap back to pins 1-2.  
3. Plug the power cord and turn ON the computer.  
4. Hold down the <Del> key during the boot process and enter BIOS setup to re-enter  
data.  
Except when clearing the RTC RAM, never remove the cap on CLRTC jumper default  
position. Removing the cap will cause system boot failure!  
If the steps above do not help, remove the onboard battery and move the jumper again  
to clear the CMOS RTC RAM data. After the CMOS clearance, reinstall the battery.  
You do not need to clear the RTC when the system hangs due to overclocking. For  
system failure due to overclocking, use the CPU Parameter Recall (C.P.R.) feature. Shut  
down and reboot the system, then the BIOS automatically resets parameter settings to  
default values.  
Due to the chipset limitation, AC power off is required before you use the C.P.R.  
function. You must turn off and on the power supply or unplug and plug the power cord  
before rebooting the system.

BIOS setup program  
This motherboard supports a programmable Serial Peripheral Interface (SPI) chip that you  
can update using the provided utility described in section “2.1 Managing and updating your  
BIOS.”  
Use the BIOS Setup program when you are installing a motherboard, reconfiguring your  
system, or prompted to “Run Setup.” This section explains how to configure your system  
using this utility.  
Even if you are not prompted to use the Setup program, you can change the configuration of  
your computer in the future. For example, you can enable the security password feature or  
change the power management settings. This requires you to reconfigure your system using  
the BIOS Setup program so that the computer can recognize these changes and record them  
in the CMOS RAM of the SPI chip.  
The SPI chip on the motherboard stores the Setup utility. When you start up the computer,  
the system provides you with the opportunity to run this program. Press <Del> during the  
Power-On Self-Test (POST) to enter the Setup utility. Otherwise, POST continues with its test  
routines.  
If you wish to enter Setup after POST, reboot the system by doing any of the following  
procedures:  
Restart using the OS standard shutdown procedure.  
Press <Ctrl>+<Alt>+<Del> simultaneously.  
Press the reset button on the system chassis.  
Press the power button to turn the system off then back on.  
Using the power button, reset button, or the <Ctrl>+<Alt>+<Del> keys to force reset from  
a running operating system can cause damage to your data or system. We recommend to  
always shut down the system properly from the operating system.  
The Setup program is designed to make it as easy to use as possible. Being a menu-driven  
program, it lets you scroll through the various submenus and make your selections from the  
available options using the navigation keys.
