Chapter 1 Product introduction Thank you for buying an ASUS® ITX-220 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 four 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.
1.3 Central Processing Unit (CPU) The motherboard comes with an onboard Intel® Celeron® 220 processor and a specially designed CPU heatsink and fan. Ensure that the CPU fan cable is connected to the onboard CPU_Fan connector.
1.4 System memory 1.4.1 Overview The motherboard comes with two Double Data Rate 2 (DDR2) Dual Inline Memory Modules (DIMM) sockets. The figure illustrates the location of the DDR2 DIMM sockets: 1.4.2 Channel Sockets Channel A DIMM_A1 Channel B DIMM_B1 Memory configurations You may install 512MB, 1GB and 2GB unbuffered non‑ECC DDR2 DIMMs into the DIMM sockets. • You may install varying memory sizes in Channel A and Channel B.
ITX-220 Motherboard Qualified Vendors Lists (QVL) DDR2-533 MHz capability DIMM socket support (Optional) Size Vendor Part No. SS/DS CL Chip No.
1.5 Expansion slot In the future, you may need to install expansion cards. The following sub‑sections describe the slot and the expansion cards that it supports. Unplug the power cord before adding or removing expansion cards. Failure to do so may cause you physical injury and damage motherboard components. 1.5.1 Installing an expansion card To install an expansion card: 1.
1.6 1. Jumpers 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. 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.
1.7 Connectors 1.7.1 Rear panel connectors 1. PS/2 mouse port (green). This port is for a PS/2 mouse. 2. LAN (RJ-45) port. This port allows Gigabit connection to a Local Area Network (LAN) through a network hub. Refer to the table below for the LAN port LED indications.
6. USB 2.0 ports 1 and 2. These two 4-pin Universal Serial Bus (USB) ports are available for connecting USB 2.0 devices. 7. USB 2.0 ports 3 and 4. These two 4-pin Universal Serial Bus (USB) ports are available for connecting USB 2.0 devices. 8. Video Graphics Adapter (VGA) port. This 15-pin port is for a VGA monitor or other VGA-compatible devices. 9. COM port. This port is for pointing devices or other serial devices. 10. PS/2 keyboard port (purple). This port is for a PS/2 keyboard. 1.7.2 1.
2. USB connector (10-1 pin USB56) This connector is for a USB 2.0 port. Connect the USB module cable to this connector, then install the module to a slot opening at the back of the system chassis. This USB connector complys with USB 2.0 specification that supports up to 480 Mbps connection speed. Never connect a 1394 cable to the USB connector. Doing so will damage the motherboard! The USB module cable is purchased separately. 3.
4. CPU and chassis fan connectors (3-pin CPU_FAN, 3-pin CHA_FAN) The fan connectors support cooling fans of 350 mA~2000 mA (24 W max.) or a total of 1 A~3.48 A (41.76 W max.) at +12V. Connect the fan cables to the fan connectors on the motherboard, ensuring that the black wire of each cable matches the ground pin of the connector. Do not forget to connect the fan cables to the fan connectors. Insufficient air flow inside the system may damage the motherboard components.
6. • • • • 1-12 System panel connector (10-1 pin F_PANEL) This connector supports several chassis-mounted functions. System power LED (2-pin PLED) 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 HD_LED) This 2-pin connector is for the HDD Activity LED.
7. 8. Serial ATA connectors (7-pin SATA1, SATA2) These connectors are for the Serial ATA signal cables for Serial ATA 3Gb/s hard disk drives and optical disk drives.
