Re: Just how standard is APM?
Yeah, I thought that APM was APM, but the apm device does nothing on my desktop with power management hardware... That is, things like 'shutdown -p now' don't work, both 'apm' and 'apmd' just return 'device not configured', etc. Interestingly, at least 'shutdown -p' does work with ACPI anyway :) Of course, maybe I'm just misunder- standing the whole thing anyway...

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?

I believe it is quite new ("designed for Windows Me").
I have to admit my ignorance - I've never heard of ACPI.

It's probably ACPI-only; welcome to FreeBSD-current. 8)
> I have to admit my ignorance - I've never heard of ACPI.
ACPI is the successor to APM, as well as trying to tie up a lot of loose
ends in other parts of the system. We're working on support for it (with
a boatload of help from Intel), but it's not quite there yet.
Don't ask about backporting. Please. 8)

It had a flaky touchpad, so I exchanged it, and took a 1700 because I wanted the CD-RW drive and lighter weight - but now I have lots of unsupported hardware (Conexant LANtastic Ethernet/modem, ESS1988 Allegro sound, and, it seems, ACPI - which is unsupported in -stable, I gather). Fortunately I have a 3Com PCMCIA EtherNIC, so I have enough working to make it quite usable with FreeBSD anyway. -- Dr Graham WheelerE-mail: [EMAIL PROTECTED] Director, Research and Development WWW:http://www.cequrux.com CEQURUX Technologies Phone: +27(21)423-6065 Firewalls/VPN SpecialistsFax:+27(21)424-3656 To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-hackers" in the body of the message

Windows (98 and newer) uses ACPI in preference to APM, so the testing that APM mode gets is usually meager at best.

For the Inspiron that you have you have to hack around a bit to get it to not hang during boot (and battery status doesn't work as a result I think), but suspend/resume on lid close work, the power button works, shutdown -p, etc. > Joe -- John Baldwin <[EMAIL PROTECTED]> -- http://www.FreeBSD.org/~jhb/ PGP Key: http://www.baldwin.cx/~john/pgpkey.asc "Power Users Use the Power to Serve!" - http://www.FreeBSD.org/ To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-hackers" in the body of the message
