wol rtl8139 or APM power off problem?

  1. Dear Fellow Subscribers,

    I am trying to get my computer to wake on LAN, but it just stays off. I am
    not sure where the problem occurs.

    I use a perl module called "Net-Wake". I have checked that the machine to
    be woken (the target machine) receives the wake-packages by logging all
    packets received on that port with ipchains.
    My BIOS (Award Modular v4.51 PG, Motherboard: M6VBE-A) has an option WOL
    and I enabled it. I also enabled the "PM by APM" option. Is that needed?
    I also have a little cable connecting NIC to the proper plug.
    When execute /usr/bin/poweroff (that's how I usually turn of my
    machine) it turns of power, but it doesn't ever wol. Should the NIC light
    be on or something after power of? It's not. Is it clear that I am in ATX
    soft power off mode or +5VSB after I do poweroff?

    To people with similar problems, the following advice has been given:
    Recompile the kernel with CONFIG_APM_REAL_MODE_POWER_OFF (this option is
    infact 'n' in my kernel)
    or boot with kernel parameter apm=power-off
    What does this have to do with it? I thought this only helps you if you
    can't do software controlled poweroff?
    By the way, apm -v gives APM BIOS 1.2 (kernel driver 1.13). I don't think
    it works correctly for when I do apm -s (that's standby) the screen
    blanks but the computer never resumes (but I am ignorant with repsect to
    apm).
    I admit I am confused.
    Let me know if you have any helpful information.

    (Net_Wake was obtained from
    http://www.perl.com/CPAN/authors/id/CLINTDW/, and listed in the Wake on
    LAN mini HOWTO)

    bw, David
