Important to note that this is usually referring to a change from the ACPI HAL back
to a STANDARD PC HAL or vice versa, and usually for W2K. MS KB articles warn against
that kind of change in W2K. This KB article for W2K:
http://support.microsoft.com/?kbid=237556
and this one for XP:
http://support.microsoft.com/?kbid=309283
and others referenced in them should answer most questions. Safest way to protect
your system is an in place repair/upgrade install though as HAL updates aren't always
fool proof..
Did you have a question or just making a further comment/clarification??
