I think I've heard rumors of some BIOS's only supporting APM in real mode; and also rumors that this was the reason for Windows sometimes shutting down so slowly - it has to do a switch to real mode to make the APM poweroff calls. Feel free to correct me if I've heard wrong :) I *know* APM in 4.2-stable did not and does not work on my laptop (some kind of Asus). The ACPI from -current worked fine once when I tested it, but I had to go back to -stable for various reasons, and now I've already gotten used to turning it off by hand after the shutdown command. (Note: no bad feelings here, if it's the BIOS's fault, there's nothing the FreeBSD developers can do about it; and no, I would not want anyone to add mode switching code to FreeBSD solely for shutdown purposes :) G'luck, Peter -- Hey, out there - is it *you* reading me, or is it someone else?
