1-20 Chapter 1: Product Overview
Plug and Play
The Processor BIOS also has a setup option to support the Windows
runtime plug and play utilities. When this option is selected, only
devices critical to boot are assigned resources by the BIOS. Device node
information is available for all devices to ensure compatibility with
Windows 95. System configuration information is stored in ESCD
format. The ESCD data is cleared upon loss of the CMOS voltage.
Advanced Power Management
The Processor BIOS has support for both 1.1 and 1.2 Advanced Power
Management (APM). The version of APM drivers loaded in the
operating system by the user determines to which specification the
BIOS will adhere. In either case, the energy saving Standby mode can
be initiated by a keyboard hot key sequence or a time-out period set by
the user.
When in Standby mode, the Processor Board reduces power
consumption by using the processor System Management Mode
(SMM) capabilities and by spinning down hard drives and turning off
VESA DPMS compliant monitors. During setup, the user may select
which DPMS mode (Standby, Suspend, or Off) is sent to the monitor.
The ability to respond to external interrupts is fully maintained while
in Standby mode allowing the system to service requests such as incoming
data or network messages while unattended. The user may
also select any keyboard or mouse activity to take the system out of the
energy saving Standby mode. When this occurs, the monitor and IDE
drives are turned back on immediately.
APM is disabled in BIOS by default; therefore, the user must enable
this feature. The system must be configured with an APM driver in
order for the system power saving features to take effect.
