With ATX power supply being used, the 586ITB system board can sup-
port ACPI Specification, Modem Wake-Up, PC 97 Compliance, and
Dual Function Power Button to enhance its performance. ACPI (Ad-
vanced Configuration Power Interface) has energy saving features
which enable operating systems to reliably manage and coordinate
power planes, PnP (Plug-and-Play) peripherals, and cooling fans. ACPI
is the specification of Microsoft
'
s PC 97 "OnNow" design allowing con-
tinual "power on" with reduced energy consumption. The Modem Wake-
Up feature allows the "sleeping" PC to power on to respond to incoming
calls.
PC 97 Compliance defines the adherence to Plug-and-Play compatibil-
ity, hardware power management, and 32-bit device drivers for
Windows
95 & Windows
NT specifications. PC 97 makes PCs easier
to use through maximum cooperation between the operating system
and hardware. Dual Function Power Button allows two distinct OFF
modes. In Sleep mode, a PC powers down but not off. In Soft-Off, a PC
shuts down but requires a reboot to "awaken" it.
