BIOS Configuration
Modem Ring Resume
When Enabled, an input signal on the serial Ring Indicator (RI) line (in other
words, an incoming call on the modem) awakens the system from Suspend
mode.
RTC Alarm Resume
When Enabled, you can set the date and time at which the RTC (real-time
clock) alarm awakens the system from Suspend mode.
Wake Up on LAN
This feature allows remote power up through a LAN connection when used in
conjunction with a Wake on LAN compliant network adapter and appropriate
software.
Primary INTR
A system peripheral signals that it wants to gain the attention of the operating
system by sending an interrupt request. When the system is in Suspend mode,
IRQ activity can cause a Primary or Secondary wake-up. When Primary INTR
is On, the IRQs in the above fields can be configured as Primary, Secondary, or
Disabled.
