This mainboard has the ACPI feature designed on the board and it will “wakeup”
automatically when it detects an incoming modem Ring-in signal. Before you can
use the Ring-in signal to wakeup your PC system, you have to install the
“External” modem to your PC system and tell the PC system which serial port
connects to the modem by selecting the IRQ in this field, (officially, COM 1 uses
IRQ4, and COM 2 uses IRQ3).
Soft-Off by PWRBTN
Pressing the power button for more than 4 seconds forces the system to enter
the Soft-Off state when the system has “hung”.
