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 will be 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 will determine to which specification the
BIOS will adhere.
In either case, the energy saving Standby mode can
be initiated by a time-out period set by the user.
When in Stand-by mode, the Processor Board reduces power
consumption by utilizing the processor System Management Mode
(SMM) capabilities and also spinning down hard drives and turning off
VESA DPMS compliant monitors
. During setup, the user may select
which DPMS mode (Stand By, Suspend, Auto, or Off) is sent to the
monitor
. The ability to respond to external interrupts is fully
maintained while in Stand-by mode allowing the system to service
requests such as in-coming data or network messages while
unattended
. The user may also make 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.
Advanced Power Management (APM) is achieved by the following:
•
DOS requires a driver (FS-APM.dos)
•
NT requires a driver (NCRSYSM.SYS)
•
Win 95 & 98 enable the BIOS APM setting, APM is disabled by
default.
•
Windows 2000 must enable the operating system APM setting. The
OS APM setting is disabled by default. NCR Gold Drivers are
enabled in this setting by selecting:
Start, Control Panel, Power Options, APM tab, check the box
Enable Advance Power Management Support , and click OK to
finish.
