The SMSC SCH3114 controller monitors several critical hardware parameters of the system, including
power-supply voltages, fan speed and CPU temperature, which are very important for a high-end
computer system to remain stable and properly. This controller is connected via the system management
(SM) bus to the south bridge.
The following parameters are monitored:
+3.3V from onboard DC/DC
®
CPU core voltage
®
+5V standby voltage
®
Battery voltage
®
CPU temperature with on-die diode
®
CPU fan speed

You can use the Hardware Monitor submenu in the BIOS Setup Utility to obtain information on voltages,
fan speed and to check the temperature of the CPU die. For more information on this submenu, see the
Appendix B: BIOS Operation chapter in this manual.
To monitor the parameters of this feature from your operating system, Kontron recommends that you
use the 32-bit protected mode JUMPtec's Intelligent Device Architecture 32-bit driver (JIDA 32) with the
test and demo application for Windows 95/98/ME/NT/2000/XP, which is available on the Kontron Web
site.
