Introduction
damage to the CPU. The onboard chassis thermal circuitry can monitor the
overall system temperature and alert users when the chassis temperature
is too high.
CPU Fan Auto-Off in Sleep Mode
The CPU fan activates when the power is turned on. It continues to operate
when the system enters Standby mode. When in sleep mode, the CPU will
not run at full power, thereby generating less heat.
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 Supero Doctor III in the Windows
OS environment or used with Supero Doctor II in Linux. SDIII 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.
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 0.83V to 1.63V. This
will allow the regulator to run cooler and thus make the system more stable.
1-5 ACPI 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 its 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, tele-
phones and stereos.
