Health
Monitoring
This section describes the PC health monitoring features of the PDSLM. The
motherboard has an onboard System Hardware Monitor chip that supports PC
health monitoring.
Onboard Voltage Monitoring
The onboard voltage monitor will scan these voltages continuously: CPU Core
Voltages, Memory (+1.8V), Chipset (+1.5V), +3.3V, +3.3V Standby, +5V, +5V
Standby, +12V, −12V and VBAT.
Once a voltage becomes unstable, it will give a
warning or send an error message to the screen. The user can adjust the voltage
thresholds to defi ne the sensitivity of the voltage monitor.
Fan Status Monitor with Firmware Speed Control
The PC health monitor can check the RPM status of the cooling fans. The onboard
fans are controlled by Thermal Management via BIOS.
1-4 Power
Confi guration Settings
This section describes the features of Power Confi guration and Power Management
of your motherboard.
BIOS Support for USB Keyboard
If the USB keyboard is the only keyboard in the system, it will function like a normal
keyboard during system boot-up.
1-5 ACPI
Features
ACPI stands for Advanced Confi guration and Power Interface. The ACPI specifi ca-
tion defi nes a fl exible and abstract hardware interface that integrates power man-
agement features with other components of a PC system, including its hardware,
operating system and application software. This enables the system to automati-
cally turn on and off peripherals such as CD-ROMs, network cards and hard disk
drives. This also includes other 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 confi 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 and Linux Operating
Systems.
