This option controls the operation of the system’s Advanced Configuration and Power Interface (ACPI) feature.

When ACPI is set to On, momentarily pressing the power button places the system in a power-saving mode. To turn the system off completely, press the power button for more than four seconds. When ACPI is set to On, interrupt request (IRQ) line 9 is not available for use by an expansion card.

When ACPI is set to Off, momentarily pressing the power button turns off the system completely. With this setting, IRQ9 is available for use by an expansion card.

Keyboard Errors enables or disables reporting of keyboard errors during the POST, which is a series of tests that the system performs on the hardware each time you turn on the system or press the reset button.

This option is useful when applied to self-starting servers or host systems that have no permanently attached keyboard. In these situations, selecting Do Not Report sup- presses all error messages relating to the keyboard or to the keyboard controller during POST. This option does not affect the operation of the keyboard itself if a keyboard is attached to the computer.
