In-Depth Information
When in Standby mode, the BIOS reduces power consumption by spinning down hard
drives and reducing power to or turning off monitors that comply with Video Electronics
Standards Organization (VESA) and Display Power Management Signaling (DPMS).
While in Standby mode, the system can still respond to external interrupts, such as those
from keyboards, mice, fax/modems, or network adapters. For example, any keyboard or
mouse activity brings the system out of Standby mode and immediately restores power to
the monitor.
In most systems, the OS takes over most of the power management settings; in some
cases, it can even override the BIOS settings. This is definitely true if the OS and mother-
board both support ACPI.
Boot Menu (Boot Sequence, Order)
The Boot menu is used for setting the boot features and the boot sequence (through
menus). If your OS includes a bootable CD—Windows XP, for example—use this menu
tochangethebootdriveordertocheckyourCDbeforeyourharddrive. Table5.22 shows
the functions and settings available on a typical motherboard.
