Continual reboots or can only boot into Safe Mode after installing WinXP
SP3?

See
http://msinfluentials.com/blogs/jesp...ng-xp-sp3.aspx
[NB: The above has been updated many times and now includes "a small tool
that will detect the IntelPPM problem and mitigate it before installing
(WinXP SP3)."]

Possible workaround: Boot into Safe Mode and rename INTELPMM.SYS to
INTELPMM.OLD.
