[CentOS] Getting Wake on lan to work
My system is: Intel CC820 motherboard (which supports PME# wake up for wake on LAN) 3com 3C905C which also supports wake on LAN via PME# Linux 5.5 The motherboard BIOS is later than one that reports an issue with WOL and this particular network card was fixed.

Although both the card and the motherboard have WOL headers my understanding is that these are not necessary if using PME# - is that correct? (I don't happen to have a WOL cable so can't just try one to confirm). How can I make Linux shutdown and leave the Ethernet power on? The common suggestion on the 'net is to remove the -i switch from the shutdown script, but it was not present to start with. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

How can I make Linux shutdown and leave the Ethernet power on? I believe you need configure the power management setting in the BIOS to leave the system in 'standby' mode or something like that, rather than 'power off'. That is, the ACPI 'power off' command yields 'standby' mode (or something like that).
