RE: [PLUG] pre-reboot scripted message?

The switch is in the hinge assembly and this is defiantly one of those
machines where one doesn't want to disturb the dust and whatnot holding it
together. Nothing in appropriate in the BIOS - though I haven't looked at
flashing it. Given more time I might revisit the physical switch. For now
though I have Gab's code which I will test today, and will also leave the
lid ajar - I'll set the screen to blank after a few minutes so the huge
crack won't detract from the lights-out-rack.
