Glossary Mainboard User's ManualPage 43 4-pin ATX Power Supply Pin Signal Name 1 Ground 2 Ground 3 +12V 4 +12V About the Soft Touch Power Button In an ATX based system, the new soft touch power button replaces the main power switch that turns your system on and off. From an OFF state, you can switch the system ON by simply pressing the power button. From an ON state, the system can be turned OFF by pressing and holding the power button for four (4) seconds OR shut down instantly. The functions of the power button can also be altered in the Power Management section in the BIOS setup. C Universal Serial Bus (USB) / Lan (Optional) Connector The Mainboard provides Two 4-pin Universal Serial Bus (USB) connectors. USB is a new interface standard for adding external Plug-and-Play (PnP) devices to the computer system. Peripherals that support USB PnP capabilities can operate at up to a 12Mb/sec data transfer rate. Eventually, all external devices connected to your computer will be standardized to USB. Mainboard User's ManualPage 44 Your mainboard may come with an optional onboard LAN func- tion. It utilizes the Intel 82562ET Physical Layer Interface, which is IEEE 10BASE-T and 100BASE-TX compliant. If your mainboard does come with an onboard LAN function, make sure it is enabled in the BIOS setting under “Integrated Peripherals” in order to use it. If you rather install and use the LAN function on the CNR card, make sure you disable the onboard LAN function and select “EXT. CNR” in the BIOS setting. The reason being that they both share the same LAN controller on the ICH2 chip. Only one physical layer interface can uses the LAN controller at a time, otherwise conflict will occur. c Universal Serial Bus (USB) Header Connect this header to the optional USB extension cable for a USB port. D Serial (COM1 & 2) Headers The Mainboard provides two 9-pins serail port headers. E Infrared (IR) Header The Mainboard provides a 5-pin header interface, IR for connection to a Hewlett Packard HSDSL-1000 compatible infrared (IrDA) transmitter/receiver. Connect IR to the front panel I/O IrDA connector provided with your system. Once the module is connected to the front panel I/O IrDA connector, Serial port 2 can be re-directed to the IrDA module. When configured for IrDA, the user can transfer files to or from portable devices such as laptops, PDA’s, mobile phone and printers using application software such as LapLink. The IrDA specification provides for data transfers at 115 kbps from a distance of 1-meter. Support for Consumer infrared (ASK-IR) is also included. Please refer to your IR equipment for more detailed information.

G Parallel Port Connector The ATX Mainboard provides a parallel port connector. Based on the ATX standard, a 25-pin parallel port is now built on the mainboard back panel. This design makes the mainboard installation easier. The parallel port can be BIOS configured into standard (SPP) mode, Enhanced Parallel Port (EPP) mode, and a high speed Extended Capabilities Port (ECP) mode. EPP Mode requires a driver provided by the peripheral manufacturer in order to operate properly. H Accelerated Graphics Port [AGP] Connector The Mainboard provides an AGP slot compatible with the Accelerated Graphics Port specification. AGP compliant video cards offer a much higher throughput than equivalent PCI bus video cards. PCI currently only supports a 33MHz bandwidth, and can transport at peak rates up to 133MB/s over its 32 bit data bus. AGP operates at a 66MHz bandwidth which enables a peak rate of 266MB/s in what is known as 'X1' mode. 'X2' mode has a peak rate of 532MB/S. 'X4' mode has a peak rate as high as 1.06GB/S. However, the 845 chipset only support the 1.5V AGP under 4X mode. Page 45 Mainboard User's Manual Mainboard User's ManualPage 46 I LITHIUM BATTERY A 3V, CR2032, Lithium battery is installed on the on-board battery socket. This battery is used to supply the CMOS RAM backup power during system powered-off. Danger of explosion if battery is incorrectly replaced. Therefore, if you have any difficulties, please consult the technical personnel. J PCI Add-In Board Connector The Mainboard provides 6 PCI Connector for the PCI cards. M Front Panel Function Connector The Mainboard integrates all system front panel functions into a single on-board connector. These include connections for the following features: Function Connector Pin-Out Label System Reset RESET Power LED / Keylock PW-LED Hard Drive Activity LED HD_ LED Soft-Touch Button Power On/Off PW-BN External Power Saving Control (optional)EXTSMI Suspend LED Sus-Led External speaker Speaker Glossary N Flash BIOS The Mainboard Flash BIOS provides users with more flexibility in upgrading their mainboards. The flash BIOS can be easily reprogrammed via software. O Floppy Drive Header The Mainboard provides a 34-pin header that supports the included floppy drive ribbon cable. After connecting the single end to the on-board “FLOPPY” header, connect the remaining plugs on the other end of the cable to the corresponding floppy drives. P IDE Device Headers The Mainboard provides two independent bus-mastering PCI IDE interfaces capable of supporting up to Mode 4 and Ultra DMA-33/66/100 devices. The system BIOS supports automatic detection of the IDE device data transfer rate and translation between different kinds of device modes such as Logical Block Addressing (LBA), Extended Cylinder Sector Head (ECSH) translation modes and ATAPI (e.g., CD-ROM) devices on both IDE interfaces. The two on-…
