Hi,

I have some questions about the high performance counter.

1. When the power is off does the high performance counter continue to tick
?

2. If not then how is the high performance counter initialized at boottime ?

3. Where can I find more information about the chip(s) for the high
performance counter ?

4. Is it possible to reset the high performance counter via a software call
?

5. How is the frequency related to the hardware ? I know it's different per
processor... but is it for example different depending on memory speed ? or
does it always have a fixed frequency ?

( note: I changed the windows xp system time to see what would happen, it
did not affect the high performance counter, so it seems not related to each
other )

p.s.: I know it's off-topic in some newsgroups I posted too but euhm... I
didn't know what newsgroup was best suited for it, I hope you understand :)

Thank you,
  Skybuck.
