Chapter 1 Product introduction Thank you for buying an ASUS® P5SD2-A motherboard! Before you start installing the motherboard, and hardware devices on it, check the items in your motherboard package. Refer to page ix for the list of accessories. If any of the items is damaged or missing, contact your retailer. 1.1 Before you proceed Take note of the following precautions before you install motherboard components or change any motherboard settings.
1.2 Motherboard overview 1.2.1 Motherboard layout Ensure that you install the motherboard into the chassis in the correct orientation. The edge with external ports goes to the rear part of the chassis. Place this side towards the rear of the chassis. Place six screws into the holes indicated by circles to secure the motherboard to the chassis. DO NOT overtighten the screws! Doing so can damage the motherboard. 1.2.2 Layout contents Connectors/Jumpers/Slots Page Connectors/Jumpers/Slots Page 1.
1.3 Central Processing Unit (CPU) The motherboard comes with a surface mount LGA775 socket designed for the Intel® Core™ 2 Duo/Pentium® D/Pentium® 4 and Celeron® processors. • Ensure that all power cables are unplugged before installing the CPU. • Upon purchase of the motherboard, make sure that the PnP cap is on the socket and the socket contacts are not bent. Contact your retailer immediately if the PnP cap is missing, or if you see any damage to the PnP cap/socket contacts/motherboard components.
• You may install varying memory sizes in Channel A and Channel B. The system maps the total size of the lower-sized channel for the dual-channel configuration. Any excess memory from the higher-sized channel is then mapped for single-channel operation. • Always install DIMMs with the same CAS latency. For optimum compatibility, we recommend that you obtain memory modules from the same vendor.

1.6 1. Jumpers Keyboard/mouse/USB device wake-up (3-pin USBPW1-4, USBPW5-8, PS2_ USBPWR) This jumper allows you to enable or disable the keyboard/mouse/USB device wake-up feature. Set this jumper to +5V to wake up the computer from S1 sleep mode (CPU stopped, DRAM refreshed, system running in low power mode) using the connected keyboard, mouse or USB devices. Set to +5VSB to wake up from S3 and S4 sleep modes (no power to CPU, DRAM in slow refresh, power supply in reduced power mode).
2. Clear RTC RAM (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 •words. To erase the RTC RAM: 1. 2. 3. 4. 5. 6. Turn OFF the computer and unplug the power cord. Remove the onboard battery. Move the jumper cap from pins 1-2 (default) to pins 2-3.
1.7 Connectors 1.7.1 Rear panel ports 1 2 3 4 5 6 1. 11 9 10 8 PS/2 Mouse port (green). This port is for a PS/2 mouse. 7 2. Parallel port. This 25-pin port connects a parallel printer, a scanner, or other devices. 3. LAN (RJ-45) port. This port allows 10/100 PHY connection to a Local Area Network (LAN) through a network hub.
1.7.2 1. Internal connectors ICH7 Serial ATA connectors (7-pin SATA1, SATA2) These connectors are for the Serial ATA signal cables for Serial ATA hard disk drives. right angle side Connect the right-angle side of SATA signal cable to SATA device. You may also connect the right-angle side of SATA cable to the onboard SATA port to avoid mechanical conflict with huge graphics cards. 2. Floppy disk drive connector (34-1 pin FLOPPY) This connector is for the provided floppy disk drive (FDD) signal cable.
3. IDE connector (40-1 pin PRI_IDE) The onboard IDE connector is for the Ultra DMA 133/100/66 signal cable. There are three connectors on each Ultra DMA 100/66/33 signal cable: blue, black, and gray. Connect the blue connector to the motherboard’s IDE connector, then select one of the following modes to configure your device.
5. Front panel audio connector (10-1 pin AAFP) This connector is for a chassis-mounted front panel audio I/O module that supports either HD Audio or legacy AC’97 audio standard. • We recommend that you connect a high-definition front panel audio module to this connector to avail of the motherboard’s high-definition audio capability.
7. ATX power connectors (24-pin EATXPWR, 4-pin ATX12V) These connectors are for ATX power supply plugs. The power supply plugs are designed to fit these connectors in only one orientation. Find the proper orientation and push down firmly until the connectors completely fit. • For a fully configured system, we recommend that you use a power supply unit (PSU) that complies with EATX 12 V Specification 2.0 (or later version) and provides a minimum power of 400 W.
9. System panel connector (10-1 pin F_PANEL) This connector supports several chassis-mounted functions. • System power LED (2-pin PWRLED) This 2-pin connector is for the system power LED. Connect the chassis power LED cable to this connector. The system power LED lights up when you turn on the system power, and blinks when the system is in sleep mode. • Hard disk drive activity LED (2-pin +HDLED) This 2-pin connector is for the HDD Activity LED. Connect the HDD Activity LED cable to this connector.
11. 12. 1-15 Chassis intrusion connector (4-1 pin CHASSIS) This connector is for a chassis-mounted intrusion detection sensor or switch. Connect one end of the chassis intrusion sensor or switch cable to this connector. The chassis intrusion sensor or switch sends a high-level signal to this connector when a chassis component is removed or replaced. The signal is then generated as a chassis intrusion event. By default , the pin labeled “Chassis Signal” and “ Ground” are shorted with a jumper cap.
