SPK (Sp eaker Connector)

An o ffboard speaker can be installe d on t he motherboard as a manufacturing option. An o ffboard s peake r ca n be connected to

the motherboard at the front panel connector. The speaker (onboard or offboard) provides error beep code information during the Power On Se lf-Test when the computer cannot use the v ideo

i nte r fac e . T he s pea ker is n ot c on nected to th e a udio s ubs ys t em and does not re c eive o utput from the audio subs ystem.

RST (Res e t Butto n )

This connector c an be attac hed to a momentary SPST switch. T his switch is usually open and when closed will cause the

POW-LED (Power LED Connector)

This connector can be attached to an LED on t he front panel of a computer case. The LED will illuminate while the computer is power e d on.

HLED (Hard Dri v e LED C on nector)

This connector can be attached to an LED on t he front panel of a computer ca se. The LED will flicker dur ing disk a ctivity. This disk ac tiv ity only applies to those IDE drives directly attached to the

system board.

IR (Infr ared Connector)

This connector is used to attach to a n infrared s e ns ing devic e. After the IrDA interface is configured, connectionless data tra ns fer to and from portable devices such as laptops, PDAs is possible.

SLP ( S leep / G reen Button)

This connector i s used to conserve energy b y poweri ng down the monitor and the hard disk when not in use. To configure this

option, you need to connect a b utton from the front panel to this connector. Depressing the button will power down the monitor

and hard drives until the system is invoked by any keyboard ac tivity, mouse activity, modem activity or when the sle ep button is depresse d again. APM (A dvanced Power Management)

mus t be enabled in the system BIOS and the APM driver must be loaded.

ON/OFF ( Pow er Button)

This connector c an be attac hed to a front panel power switch. T he switch m ust pull the Power Button pin to ground for at least 50 ms

to sign al the power suppl y to switch on or off. (The time requi red is due to internal debounce circuitry on the system board). At

least two seconds must pass before the power supply will recognize another on/of f signal.

DMA / 66,Ultra DMA / 100 functionality. It has two HDD connectors IDE1 (prima ry) and IDE2 (s econdary).

• ID E1 (Pr imary IDE Connecto r)

The first hard drive should always be connected to IDE1. IDE1 can connect a Master and a S lave drive. Y ou must configure the

second hard drive o n IDE1 to Slave mode by setting the j umper acco rdingly.

• ID E2 (Secondar y I DE Connector)

The IDE2 controller can also support a Master and a Slave drive. The configuration is s imilar to IDE1. The second drive on this

con tro ll er m u st be set to sla ve mode.

4-5. Floppy Disk Connector: FDD1

The mot h erboard provides a standard floppy disk conn ector (FDC) that sup ports 360K, 720K , 1.2M, 1 .44M and 2 .88M floppy disk

types. This connector s upports the provided floppy drive ribbon cables.
