PWRON After PW-Fail
In case of power failure, the system can be configured to power on or to
remain off when the power returns. These two settings are
Former-Sts
and Off respectively. The default setting for this field is Off .
PM Events
The VGA, LPT & COM, HDD & FDD, DMA /master, GPI Resume,
Modem Ring Resume, RTC Alarm Resume and Primary INTR section
are I/O events which can prevent the system from entering a power saving
mode or can awaken the system from such a mode. When an I/O device
wants to gain the attention of the operating system, it signals this by
causing an IRQ to occur. When the operating system is ready to respond
to the request, it interrupts itself and performs the service. The default
value is
Off . When set On, activity will neither prevent the system from
going into a power management mode nor awaken it. The IRQ section
sets the wake-up call of the system. If activity is detected from any
enabled IRQ channels in the left-hand group, the system wakes up from
suspended mode.
PWR-ON By Modem/LAN
This field allows powering on the system through a modem connected in
one of the serial ports or by network.
