Power awareness

[Bill Butler]

Joel,

I have tried for the past 2 days to use the user list archive search
engine and get a failure message when searching (Internal Server Error).
I have tried it under Explorer/2000 and Netscape/linux with the same
results. 

Is it something on my end or Oarcorp?

Thanks

There is no variable power management capability right now but there is
a place to insert a switch to idle/low power mode.  Some CPUs and BSPs
have a special version of the IDLE task which puts the CPU in a low
power
state.  But there is nothing that says we are only 10% CPU utilization
so
lower the clock rate.
