ACPI/PC 98 Features
ACPI stands for Advanced Configuration and Power Interface. The ACPI
specification defines a flexible and abstract hardware interface that pro-
vides a standard way to integrate power management features throughout
a PC system, including hardware, operating system and application soft-
ware. This enables the system to automatically turn on and off peripherals
such as CD-ROMs, network cards, hard disk drives, and printers. This also
includes consumer devices connected to the PC such as VCRs, TVs,
phones, and stereos.
In addition to enabling operating system-directed power management, ACPI
provides a generic system event mechanism for Plug and Play and an oper-
ating system-independent interface for configuration control. ACPI lever-
ages the Plug and Play BIOS data structures while providing a processor
architecture-independent implementation that is compatible with both Win-
dows 98 and Windows NT 5.0.
Microsoft OnNow
The OnNow design initiative is a comprehensive, system-wide approach to
system and device power control. OnNow is a term for a PC that is always
on but appears off and responds immediately to user or other requests.
Slow Blinking LED for Suspend-state Indicator
When the CPU goes into a suspend state, the power LED will start blinking
to indicate that the CPU is in suspend mode. When the user presses any
key, the CPU will wake-up and the LED will automatically stop blinking and
remain on.
BIOS Support for USB Keyboard
If the USB keyboard is the only keyboard in the system, the USB keyboard
will work like a normal keyboard during system boot-up.
