System Resource Alert
This feature is available when used with Supero Doctor III in the Windows OS en-
vironment or used with Supero Doctor II in Linux. Supero Doctor is used to notify
the user of certain system events. For example, if the system is running low on
virtual memory and there is insuf
fi cient hard drive space for saving the data, you
can be alerted of the potential problem. You can also con fi gure Supero Doctor to
provide you with warnings when the system temperature goes beyond a pre-de-
fi ned range.
1-5 ACPI Features
ACPI stands for Advanced Con fi guration and Power Interface. The ACPI speci fi ca-
tion de fi nes a fl exible and abstract hardware interface that provides a standard
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
provides a generic system event mechanism for Plug and Play and an operating
system-independent interface for con
fi guration control. ACPI leverages the Plug
and Play BIOS data structures while providing a processor architecture-indepen-
dent implementation that is compatible with both Windows 2000 and Windows
Server 2003. This setting is also located in the Advanced BIOS Setup section
(Boot Features).
Slow Blinking LED for Suspend-State Indicator
When the CPU goes into a suspend state, the chassis 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.
Main Switch Override Mechanism
When an ATX power supply is used, the power button can function as a system
suspend button to make the system enter a SoftOff state. The monitor will be
suspended and the hard drive will spin down. Pressing the power button again
will cause the whole system to wake-up. During the SoftOff state, the ATX power
supply provides power to keep the required circuitry in the system alive. In case
the system malfunctions and you want to turn off the power, just press and hold
the power button for 4 seconds. This option can be set in the Boot section of the
Advanced BIOS Setup routine.
