Watchdog
A watchdog timer (WDT) is a device that performs a specific
operation after a certain period of time if something goes
wrong and the system does not recover on its own. A watch-
dog timer can be programmed to perform a warm boot
(restarting the system) after a certain number of seconds.
Hardware Monitor
The Hardware Monitor (HWM) API is a system health super-
vision API that inspects certain condition indexes, such as
fan speed, temperature and voltage.
CPU Speed
Makes use of Intel SpeedStep technology to save power
consumption. The system will automatically adjust the CPU
speed depending on the system loading.
System Throttling
Refers to a series of methods for reducing power consump-
tion in computers by lowering the clock frequency. This API
allows the user to adjust the clock from 87.5% to 12.5%.
BIOS Flash
The BIOS Flash utility allows customers to update the
flash ROM BIOS version, or use it to back up current BIOS
by copying it from the flash chip to a file on the customers’
disk. The BIOS Flash utility also provides a command line
version and an API for fast implementation into custom-
ized applications.
Embedded Security ID
The embedded application is the most important property
of a system integrator. It contains valuable intellectual
property, design knowledge and innovation - but it is easy
to be copy. Embedded Security ID utility provides reliable
security functions for customers to secure their application
data within embedded BIOS.
