[lug] ACPI and power off

[D. Stimits]

I'm looking at a motherboard that supports BIOS setting of ACPI version
1, 2, or 3. Is one more appropriate than another for a modern distro,
e.g., FC7? I'm asking because I'm trying to get a machine to actually
power down when told to halt, but under all 3 settings, stock kernel for
FC7, it is still leaving power on. I'm thinking that a long time ago,
there was a file in /etc/ that could be set to tell it power off and not
just halt state. Anyone know what is required for power off to work?
