MODEM Use IRQ
This determines the IRQ which the MODEM can use for power saving purposes. This main-
board 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).
