Yes I know now... and it does work the only problem now is that I've only seen it once because I never turn the machine off !! :) On Tue, 16 Feb 1999, Warner Losh wrote: > In message Matthew Thyer > writes: > : I have "apm" in the kernel and it probes as apm v 1.2 but when > : the "shutdown -p now" command is run, the power is not turned > : off and I have to hold down the power button for 4 seconds to > : turn it off. > : > : Hows it done ? > > You need to set apm_enabled="YES" in your rc.conf file. > > Warner > > /=\ |Work: matthew.th...@dsto.defence.gov.au | Home: thy...@camtech.net.au| \=/ "If it is true that our Universe has a zero net value for all conserved quantities, then it may simply be a fluctuation of the vacuum of some larger space in which our Universe is imbedded.

No, they were added after the split and weren't backported to the 3.x branch. But if you are impatient, you could just grab a copy of sys/kern/kern_shutdown.c from a 4.0 branch and copy it to your tree. The added sysctl is for now the only difference in this file. Then you can specify somewhere in your rc files sysctl -w kern.shutdown.poweroff_delay = x with x measured in ms. I have only seen one machine so far which suffers this problem of powering off the machine too fast. On all other machines I know of either the mainboard or the power supply (don't know which) have a small delay before powering off the machine, which seems to be long enough for the drives to flush their buffers. On this particular machine, I set the delay to 1.5 seconds, and I never got unclean filesystems again.

However, at bootup I get the message: "Warning: / not unmounted properly" Could it be because the system thinks everything is flushed, but something is still in the disk's write-cache? (If such a beast exists...) Is a delay needed between the final sync's and the actual power off? l...@neland.dk To Unsubscribe: send mail to majord...@freebsd.org with "unsubscribe freebsd-current" in the body of the message

Well I thought, I have apm enabled, apm(1) shows that. The probe shows that and so on. A little further checking and it was using flags 0x31 by default.. presumably to avoid using possibly buggy APM 1.2 features? Anyhow.. that caused apm to return results like: APM version: 1.2 APM Managment: Enabled AC Line status: on-line Battery status: unknown Remaining battery life: unknown Remaining battery time: unknown Number of batteries: unknown Resume timer: disabled Resume on ring indicator: enabled APM Capacities: unknown Note there's no mention of the limiting to version 1.1 or 1.0. Anyhow.. try rebooting with the flags set to 0x0 and see if that works. I assume that if you've got an ATX mobo, the BIOS is new enough that the APM implementation shouldn't be too buggy... - alex To Unsubscribe: send mail to majord...@freebsd.org with "unsubscribe freebsd-current" in the body of the message

Do you use the "Power up at " feature of the BIOS?

It doesn't work in all cases, though. It sure doesn't work on _my_
machine.

Yes. There is a knob in /etc/rc.conf ("apm_enable") that forces
this at startup.

How to power off an ATX power supply machine on shutdown ?
Sorry if this is inappropriate for -CURRENT but I am mailing here as the answer may be to do with recent committed features to -CURRENT (intpm ??). Anyway, how do I power off a machine on shutdown ? I have "apm" in the kernel and it probes as apm v 1.2 but when the "shutdown -p now" command is run, the power is not turned off and I have to hold down the power button for 4 seconds to turn it off. Hows it done ? Do I have to run "apmconf -e" (The owner hasn't tried this yet) I cant give more info as it's not my machine and I only see it on weekends. /=\ |Work: matthew.th...@dsto.defence.gov.au | Home: thy...@camtech.net.au| \=/ "If it is true that our Universe has a zero net value for all conserved quantities, then it may simply be a fluctuation of the vacuum of some larger space in which our Universe is imbedded.
