1-5 Acpi/Pc 98 Features - Supero SUPER P3TDLR User Manual

CPU Overheat LED and Control
This feature is available when the user enables the CPU overheat warning
function in the BIOS. This allows the user to define an overheat tempera-
ture. When this temperature is exceeded, both the overheat fan and the
warning LED are triggered.
System Resource Alert
This feature is available when used with Intel's LANDesk Client Manager (op-
tional). It is used to notify the user of certain system events. For example, if
the system is running low on virtual memory and there is insufficient hard drive
space for saving the data, you can be alerted of the potential problem.
Hardware BIOS Virus Protection
The system BIOS is protected by hardware so that no virus can infect the BIOS
area. The user can only change the BIOS content through the flash utility
provided by SUPERMICRO. This feature can prevent viruses from infecting the
BIOS area and destroying valuable data.
Auto-Switching Voltage Regulator for the CPU Core
The auto-switching voltage regulator for the CPU core can support up to 20A
current and auto-sense voltage IDs ranging from 1.4V to 3.5V. This will allow the
regulator to run cooler and thus make the system more stable.

1-5 ACPI/PC 98 Features

ACPI stands for Advanced Configuration and Power Interface. The ACPI speci-
fication defines a flexible and abstract hardware interface that provides a stan-
dard way to integrate power management features throughout a PC system,
including its hardware, operating system and application software. 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, telephones and stereos.
In addition to enabling operating system-directed power management, ACPI pro-
vides a generic system event mechanism for Plug and Play and an operating
system-independent interface for configuration control. ACPI leverages the Plug
and Play BIOS data structures while providing a processor architecture-indepen-
dent implementation that is compatible with both Windows 98 and Windows NT
