MSE/KYBD mouse and keyboard interfaces.

CD_IN1 and JCD indicate the CD audio input interfaces.

AUX_IN1 and JAUX indicate the line audio input interfaces.

JAUDIO or AUDIO indicates the onboard AUDIO output interface. If your chassis has front-end headphones and microphone jacks and their interfaces comply with the onboard AUDIO interface, you can conveniently use both front-end and back-end AUDIO output. You do not have to pull it back and forth. // This article is from the computer software and hardware Application Network www.45it.com

F_AUDIO front-end audio input and output interfaces.

MODEM IN1 has built-in MODEM input interface.

Battery:

JBAT1 motherboard battery discharge jumper

BAT1 or BT indicates that the CMOS information of the motherboard saves the battery.

 

JP10 (usually near the battery)

1-2
NORMAL
Normal use mode

2-3
CLEAR CMOS
Clear CMOS content

 

Enable NIC:

JP4 ON BOARD LAN

1-2 ENABLE Nic remote start allowed

2-3
DISABLE
Nic remote start prohibited

 

Enable the keyboard:

If you want to use the keyboard boot function, you need to enable the keyboard boot settings in CMOS, you also need to configure jumper settings on the motherboard.

Note: When the keyboard is powered by a 5VSB power supply, the keyboard and mouse power-on functions are allowed, but when the power is turned off (when the host power plug is not unplugged), the keyboard or mouse light will remain on.

JP1 (the keyboard boot jumper is generally near the keyboard interface)

 

1-2
KEYBOARD POWER ON DISABLE
Enable keyboard boot

2-3 KEYBOARD POWER ON ENABLE
Disable keyboard boot

 

Frequency Doubling outer Frequency Jumper settings:

Motherboard model identification:

When we upgrade the BIOS of the motherboard, we must correctly identify the model and PCB version number of the motherboard. Because some motherboard models are the same, but the chip may change during the production process, there will be a difference in the PCB version number. Therefore, you must download the appropriate BIOS code when upgrading the BIOS. The BIOS chip is stored in flash eeprom. In the past two years, the motherboard has adopted a square chip to save installation space. The first sign of the square chip is a small dot in the middle of one side.

For example, GA-8IR533 REV: 1.0 followed by 1.0 is the PCB version number.

Identification of Sound Card chips:

Most of the current boards are integrated with onboard sound cards. When we install a motherboard driver, if we do not know the model of the sound card, we can open the chassis and carefully identify the words above the sound card chip, you can find the model of the sound card. The size of the sound card chip on the motherboard is about 6mm * 6mm, and its peripheral pins are intensive.

Motherboard USB:

The 5 V power supply method of the on-board USB interface varies with the manufacturer of the main board. Some use the main 5 V power supply, some use the 5 VSB power supply of the auxiliary power supply, and some use the jumper to change. The jumper is usually located near the USB interface.

Note: If you use a power supply of 5 VSB, because it uses 7805 integrated circuit regulator, the maximum output current is 1.5A, but in fact, when no heat sink is added, the maximum is Ma, the power supply also powers the keyboard, the modem remotely wakes up, and the nic powers up. Therefore, when we use USB interfaces for peripherals with high power consumption (such as mobile hard disks and USB scanners), the mobile hard disks may not work properly due to insufficient current, in this case, you can use the keyboard or mouse interface that comes with the mobile hard disk to obtain some current from the keyboard or mouse interface for normal operation. You can also use an external power supply.

In addition, the front USB interface of the motherboard and the rear USB interface may have different power supply methods, which may cause a USB peripheral to work normally when the front USB interface is used, however, the backend USB interface does not work properly. In this case, we 'd better read the instruction manual for the motherboard and peripherals carefully.
