Serial ATA Connectors: SATA1 and SATA2

These next generation connectors support the thin Serial ATA
cables for primary internal storage devices. The current Serial
ATA interface allows up to 150MB/s data transfer rate, faster
than the standard parallel ATA with 133 MB/s (Ultra DMA).

SATA1-2

USB Pin Connector: USB

The mainboard provides one USB pin header, allowing up to 2 additional
USB2.0 ports up to maximum throu ghput of 480 Mbps. Connect each 2-por t
USB cable into this pin header. This port can be used to connect high-speed
USB interface peripherals such as USB HDD, digital cameras, MP3 players,
printers, modem and the like.

JUMPERS

The mainboard provides jumpers for setting some mainboard functions. Th is
section will explain how to change the settings of the mainboard functions
using the jumpers.

Clear CMOS: CLEAR_CMOS

The onboard CMOS RAM stores system configuration d ata and has an
onboard battery power supply. To reset the CMOS settings, set the jumper
on pins 2 and 3 while the system is off. R eturn the jumper to p ins 1 and 2
afterwards. Setting the jumper while the system is on will damage the
mainboard.
