21 Hardware Monitor
The Winbond W83627HF 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 function properly. This controller is connected via the SM
(System Management) 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 (planed)
21.1 Configuration
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 JUMP
tec
’s Intelligent Device Architecture 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.
