I didn’t see anything obvious when I looked either. Could be it was never
documented prior to the last RBIL update. Or, like you said possibly never
standardized.
But after looking at Resume by Alarm
<https://fd.lod.bz/rbil/zindex/idx-resume_by_alarm.html> and Power Management
<https://fd.lod.bz/rbil/interrup/power/index.html>, I was thinking maybe there
is a trick. I wonder what would happen if you programmed it to “Resume” in the
past. Would it refuse, clear it, wait for the clock to roll over or wake
immediately. I suspect all of the above depending on the BIOS. Maybe if set
everything to 0xffff, it would wake instantly. But, thats all just guesswork on
my part.
