Right, and the BIOS controls that behaviour. The apm module of the kernel, for instance, communicates to the system BIOS, telling it to power down when you do the 'shutdown -h now' command. (If you don't have the apm modules running, the kernel gives you a message at the end "Power off" -- and you have to manually turn off the machine.) > If one simply tells the BIOS that when the power button is held down and > it forces a poweroff, I'd hope you're running a journaling FS and didn't > have processes running in the background. Exactly -- which is why the OP was wondering if there'd be a way to get around this. Another poster has mentioned ACPI; I'm not familiar with how it works as I don't have any ACPI-enabled machines. The info I gave is based on what I've seen on several laptops' (as well as desktops') configuration items in the BIOS for power and suspend buttons -- things such as not powering down unless the power button is held in for 4 seconds, etc. -- Matthew Weier O'Phinney [EMAIL PROTECTED] -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
