Modem Use IRQ
This determines the IRQ which the MODEM can use for Power Saving pur-
poses. This mainboard has the ACPI feature designed on the board and it will
“wake-up” 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
COM1 uses IRQ4)

agement Signaling (DPMS) standard of the Video Electronics Stan-
dards to select video power management values.
