维修判据：
SUSCLK波形的占空比如果落在30%～70%这个范围以外，表示这个32.768kHz振荡器已经性能不良。作者: 张先生 时间: 2009-4-8 19:39
ICH10的VccRTC：
3.3 V (can drop to 2.0 V min. in G3 state) supply for the RTC well. This power
is not expected to be shut off unless the RTC battery is removed or completely
drained.
Note: Implementations should not attempt to clear CMOS by using a jumper
to pull VccRTC low. Clearing CMOS in an Intel ICH10-based platform can be
done by using a jumper on RTCRST# or GPI .
ICH10的VccRTC:
对RTC的3.3V（G3状态最小可以降到2V）供电要一直保持良好。除非RTC电池被取走或者完全失电，该电源不应该被关掉。
注意：不要用跳线拉低VccRTC来清除CMOS，在ICH10平台上可以在RTCRST#或GPI用跳线来清除CMOS。作者: 张先生 时间: 2009-4-8 19:47
ICH10 External RTC Circuitry
The ICH10 implements an internal oscillator circuit that is sensitive to step voltage
changes in VccRTC. Figure 2-1 shows an example schematic recommended to ensure correct operation of the ICH10 RTC.
