Given the following situation: Everything is prepared for "Wake-on-LAN", but unfortunately on the PC to be woken up, "Wake-on-LAN" is disabled in the BIOS and this setting can not be changed because you have only remote (root) access to that PC.

Is there a chance to override the "wrong" BIOS setting within a running Linux, e.g. using the /proc or /sys filesystem, before that PC is shut down?

Afraid not. Once the system is shutdown there is noting left of the OS to
tell the system what to do. You need someone on that site to setup the
BIOS for you. Wouldn't it be better to just leave the system running?



And *THIS* sort of wackiness is why I want LinuxBIOS to become more popular. The OLPC is using it quite effectively, I've got reports of it being used for renderfarms, and it's exciting stuff to address precisely this sort of wackiness.
