" NICs appear to require a WOL reminder on shutdown. I don't know if that's an ACPI or a PCI issue yet, but some newer NICs seem to behave badly. I really haven't spent much time on this to understand clearly what the issues are.
I took my old Compaq Deskpro - this is a 1998 vintage 500 MHz Celeron based system, it's equipped with a Compaq supplied 3Com 3C905 PCI 10/100 ethernet card with the three wire WOL cable - pulled the hard drive and reset the CMOS - powered it on from the front panel and set the date & time (to get rid of the 161 & 163 errors.)
Using the SolarWinds WOL tool, from the SolarWinds Engineer's ToolSet (evaluation edition), I can turn the system on - that is with no hard drive, and therefore no OS or drivers and no special configuration of the CMOS. It quite happily boots from whatever CD is in the drive and it doesn't care how I shut it down, an orderly shutdown, force it off by holding down the front panel button, or crudely yanking the AC cord out of the outlet - I send a WOL packet and up it comes.
The strange thing is - WOL wakes the unit 100% of the time, and the reason why I took the unit out of service in mid February is that it takes two or three pushes of the front panel button to get it to come on and stay on.
I also played around with the replacement system - a 2006 vintage Dell Optiplex GX280 - this one is a 3 GHz P4 hyperthreading system, with a Broadcom integrated gigabit ethernet LOM, running Windows XP - I did have to enable WOL in the CMOS setup on this one, but again, no matter how it's shut down, it wakes right up.
