1-20 Chapter 1: Product introduction 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. 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. Refer to the tables on the next page. 3. Install the software drivers for the expansion card. Make sure to unplug the power cord before adding or removing expansion cards. Failure to do so may cause you physical injury and damage motherboard components. 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. Refer to the table on the next page for details. P5Q-EM DO.indb 20 12/9/08 12:34:00 PM

P5Q-EM DO P5Q-EM DO Clear RTC RAM 1 2 2 3 Normal (Default) Clear RTC CLRTC Except when clearing the RTC RAM, never remove the cap on CLR TC jumper default position. Removing the cap will cause system boot failure! 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 5âÂÂ10 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. ⢠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 C.P .R. (CPU Parameter Recall) feature. Shut down and reboot the system so the BIOS can automatically reset parameter settings to default values. ⢠Due to the chipset behavior , AC power off is required to enable 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. P5Q-EM DO.indb 24 12/9/08 12:34:11 PM

1-20 Chapter 1: Product introduction 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. 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. Refer to the tables on the next page. 3. Install the software drivers for the expansion card. Make sure to unplug the power cord before adding or removing expansion cards. Failure to do so may cause you physical injury and damage motherboard components. 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. Refer to the table on the next page for details. P5Q-EM DO.indb 20 12/9/08 12:34:00 PM

Removing the cap will cause system boot failure! 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 5âÂÂ10 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. ⢠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 C.P .R. (CPU Parameter Recall) feature. Shut down and reboot the system so the BIOS can automatically reset parameter settings to default values. ⢠Due to the chipset behavior , AC power off is required to enable 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. P5Q-EM DO.indb 24 12/9/08 12:34:11 PM
