The earliest ACPI spec I have handy is 1.0b, which came out in Feb 2 1999 so this isn't true. The all knowing (and always accurate :) wikipedia claims it was first released in 1996, though I believe that all the pre 1.0b machines were using acpi implementations before the standard was finalised. I certainly remember seeing ACPI capable machines circa 1997/1998. Dave -- http://www.codemonkey.org.uk
