ESD Precautions
Computer boards have integrated circuits sensitive to static electricity. To prevent chipsets from electrostatic discharge damage, please take care of the following jobs with precautions:
Do not remove boards or integrated circuits from their anti-static packaging until you are
ready to install them.
Before holding the board or integrated circuit, touch an unpainted portion of the system
unit chassis for a few seconds. It discharges static electricity from your body.
Wear a wrist-grounding strap, available from most electronic component stores, when
handling boards and components.

Note: If your computer can not boot after making and saving system changes with Setup,
you can restore BIOS optimal defaults by setting JP9 (see section 2.3.6).
It is strongly recommended that you should avoid changing the chipset’s defaults. Both AMI

About Digital I/O
The onboard digital I/O has 8 bits (DI0~2 and DO0~4). Each bit can be set to function as input
utput by software programming. In default, all pins are pulled high with +5V level
or o
(according to main power).

Note1:
The N has 8 bits. Only bit
" 1" means that the bit is programmed to input.
" 0" means that the bit is programmed to output.
s 5,6,7 are programmable.
Ex:
N=
E0h=11100000b
Bit7 Bit6 Bit5 Bit4 Bit3 Bit2 Bit1 Bit0

No use No use No use No use No use
Note2:
1. When DI0~2 are connected to external device, the device sets DI0~2 to high Bit7 Bit6 Bit5 Bit4 Bit3 Bit2 Bit1 Bit0
DI2 = 1 DI1 = 1 DI0 = 1
No use No use No use No use No use
2. When DI0~2 are connected to external device, the device sets DI0 to low and DI1~2 to high Bit7 Bit6 Bit5 Bit4 Bit3 Bit2 Bit1 Bit0
DI2 = 1 DI1 = 1 DI0 = 0
No use No use No use No use No use

Note3:
The X has 8 bits. Only bits 0,1,2,3,4 are programmable.
" 1" means that the bit is programmed to input.
