The drift itself wasn't what I'd call excessive,
something like 6 minutes in a week, which for
mainboard quality crystals is pretty darned good.

I didn't discover it wasn't working till my watch beeped
at me on the hour like it always does (casio) and I glanced
at the cornerclock to see it said it was 6 minutes & some
after the hour. So either my watch was funkity, or the ntpd.
My watch has been *very* reliable, staying within 10 seconds
a month, so I discounted that theory and went after ntpd.

After my experience, I'd recommend any nforce2 board get
the latest bios and install it. On this biostar though,
I then had to go into the expert mode on the 3rd screen
and play for a while till I had restored the DDR to 333 mhz,
the defaults want to run it at 400 mhz, and an XP2800
athlon will only stay up 10 minutes or so at 40, as its
only rated at 333. The faster athlons, Xp3200+ chips,
are rated for 400 though.

But in my case, I think that was the only 'gotcha', and
everything else seems to be as happy as that infamous pig
in you know what.

When its running, drift file contents have not to my knowledge ever
exceeded 6.000, and are currently running like this:
drift=4.236
remote refid st t when poll reach delay offset jitter

LOCAL(0) LOCAL(0) 10 l 6 64 377 0.000 0.000 0.001
drift=4.236

I have a while true script logging the drift and the output of
ntpq -p into /var/log/ntp.log every half hour temporarily.
