8. USB 3.2 Gen 1 header

The USB 3.2 Gen 1 header allows you to connect a USB 3.2 Gen 1

module for additional USB 3.2 Gen 1 ports. The USB 3.2 Gen 1 header

provides data transfer speeds of up to 5 Gb/s.

The USB 3.2 Gen 1 module is purchased separately.

9. USB 2.0 headers

The USB 2.0 headers allow you to connect USB modules for additional USB 2.0

ports. The USB 2.0 headers provide data transfer speeds of up to 480 Mb/s.

DO NOT connect a 1394 cable to the USB connectors. Doing so will damage

the motherboard!

The USB 2.0 module is purchased separately.

10. Clear CMOS header

This header allows you to clear the CMOS RTC RAM data of the system setup

information such as date, time, and system passwords.

To erase the RTC RAM:

Turn OFF the computer and unplug the power cord.

Use a metal object such as a screwdriver to short the two pins.

Plug the power cord and turn ON the computer.

Hold down the <Del> key during the boot process and enter BIOS setup to re-

enter data.

If the steps above do not help, remove the onboard battery and short the two pins again to

clear the CMOS RTC RAM data. After clearing the CMOS, reinstall the battery.

This header is for a serial (COM) port. Connect the serial port module cable to

this header, then install the module to a slot opening at the back of the system

chassis.

I/O module cable to this header.

audio module to this header to avail of the motherboard's high-

definition audio capability.

•

If you want to connect a high-definition front panel audio

module to this header, set the Front Panel Type item in the

BIOS setup to [HD Audio]. By default, this header is set to [HD

Audio].
