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.

BIOS Configuration
Prim ary
The system w akes up fully w hen it detects IRQ activity.
Secondary
The system does not w ake up, but the interrupt request
is processed. Secondary interrupts are typically
housekeeping devices needed to maintain the system
w hile not requiring the use of the rest of the system
resources. For example, IRQ8, the RTC alarm, is
configured as Secondary by default. Another example
might be a netw ork adapter continually polled by the
netw ork.
