BIOS Configuration

DozeMode

After the selected period of system inactivity (1 minute to 1 hour), the CPU clock runs at slower speed while all other devices still operate at full speed.

Suspend Mode

After the selected period of system inactivity (1 minute to 1 hour), all devices except the CPU shut off.

** PM Events **

A power management (PM) event awakens the system from, or resets activity timers for, Suspend mode. You can disable monitoring of common interrupt requests so they do not generate PM events.

VGA

When On, any video activity is a PM event.

LPT & COM

Select none, or one or more, ports whose activity is a PM event.

HDD & FDD

When On, any hard drive or floppy drive activity is a PM event.

DMA/master

When On, any DMA or bus master activity is a PM event.

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
