Option Heading
Power-On Options Allows you to set:
●
POST messages (enable/disable). Enabling this feature will cause the system to display POST error
messages, which are error messages displayed on the monitor during the Power On Self Test if the
BIOS encounters some kind of problem while starting the PC. A POST error message will only display
on screen if the computer is capable of booting this far. If the POST detects an error before this
point, a beep code is generated instead. Default is disabled.
●
After Power Loss (o/on/previous state). Default is Power o. Setting this option to:
–
Power o—causes the computer to remain powered o when power is restored.
–
Power on—causes the computer to power on automatically as soon as power is restored.
–
Previous state—causes the computer to power on automatically as soon as power is restored,
if it was on when power was lost.
NOTE: If you turn o power to the computer using the switch on a power strip, you will not be able to
use the suspend/sleep feature or the Remote Management features.
●
POST Delay (in seconds). Enabling this feature will add a user-specied delay to the POST process.
This delay is sometimes needed for hard disks on some PCI cards that spin up very slowly, so slowly
that they are not ready to boot by the time POST is nished. The POST delay also gives you more
time to select F10 to enter Computer (F10) Setup. Default is None.
●
Remote Wakeup Boot Source (remote server/local hard drive). Default is Local hard drive.
BIOS Power-On Allows you to set the computer to turn on automatically at a time you specify.
Bus Options Allows you to enable or disable:
●
PCI SERR# Generation. Default is enabled.
●
PCI VGA Palette Snooping, which sets the VGA palette snooping bit in PCI conguration space; only
needed when more than one graphics controller is installed. Default is disabled.
Device Options Allows you to set:
●
Num Lock State at Power-On (o/on). Default is o.
●
Multi-Processor (enable/disable). Default is enabled.
