Power-On from Space-Bar

The power-on from the space-barfunction is enabled, provided that:

•The computer is connected to a Power-On keyboard (recognizable by the Power-On icon on the space bar).

•The computer is running a Windows operating system.

•The function has not been disabled by setting SW-8 to open on the system board switches.

•The function has not been disabled in the “Power” menu of the Setup program.

Soft Power Down

When the user requests the operating system to shutdown, the environment is cleared, and the computer is powered off. Soft Power Down is available with the Windows NT and Windows 95 operating systems.

The hardware to do this is contained within the PIIX4. This chip is described on page 50.
