1-5 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.
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 Windows98.
In order to enable ACPI, the default APM mode must be disabled in BIOS
(see page 5-12). To install Windows 98 with ACPI, enter DOS and type
"setup /p j" at the CDROM prompt (usually D:\) with the Windows98 CD
loaded. (Make sure you include the spaces after "setup" and "p".) Then hit
<Enter>. You can check to see if ACPI has been properly installed by
looking for it in the Device Manager, which is located in the Control Panel in
Windows.
Microsoft OnNow
The OnNow design initiative is a comprehensive, system-wide approach to
system and device power control. OnNow is a term describing a PC that is
always on but appears to be off and that responds immediately to users
and 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 a USB keyboard is the only keyboard in the system, it will function like a
normal keyboard during system boot-up.
