ASUS P5QL-CM 1-19 1.8 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 T o 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. Remove the system unit cover (if your motherboard is already installed in a chassis). 3. 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 îÂÂrmly until the card is completely seated on the slot. 5. Secure the card to the chassis with the screw you removed earlier . 6. Replace the system cover . 1.8.2 ConîÂÂguring an expansion card After installing the expansion card, conîÂÂgure it by adjusting the software settings. 1.

1-20 Chapter 1: Product introduction 1.9 Jumpers 1. Clear RTC RAM (3-pin CLRTC) This jumper allows you to clear the Real T ime Clock (RTC) RAM in CMOS. Y ou 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. 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 . ⢠Y ou 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. Y ou must turn off and on the power supply or unplug and plug the power cord before rebooting the system. T o erase the RTC RAM: 1. T urn 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. P5QL-CM P5QL-CM Clear RTC RAM 1 2 2 3 Normal (Default) Clear RTC CLRTC

ASUS P5QL-CM 1-19 1.8 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 T o 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. Remove the system unit cover (if your motherboard is already installed in a chassis). 3. 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 îÂÂrmly until the card is completely seated on the slot. 5. Secure the card to the chassis with the screw you removed earlier . 6. Replace the system cover . 1.8.2 ConîÂÂguring an expansion card After installing the expansion card, conîÂÂgure it by adjusting the software settings. 1. T urn on the system and change the necessary BIOS settings, if any . See Chapter 2 for information on BIOS setup. 2. Assign an IRQ to the card. 3. Install the software drivers for the expansion card. When using PCI cards on shared slots, ensure that the drivers support âÂÂShare IRQâ or that the cards do not need IRQ assignments. Otherwise, conîÂÂicts 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 speciîÂÂcations. 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 speciîÂÂcations. 1.8.5 PCI Express x16 slot This motherboard supports a PCI Express x16 graphics card that complies with the PCI Express speciîÂÂcations.
1-20 Chapter 1: Product introduction 1.9 Jumpers 1. Clear RTC RAM (3-pin CLRTC) This jumper allows you to clear the Real T ime Clock (RTC) RAM in CMOS. Y ou 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. 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 . ⢠Y ou 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. Y ou must turn off and on the power supply or unplug and plug the power cord before rebooting the system. T o erase the RTC RAM: 1. T urn 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. P5QL-CM P5QL-CM Clear RTC RAM 1 2 2 3 Normal (Default) Clear RTC CLRTC
