The 911 equivalent in Australia is 000. Just sayin’

It might be a jumper on the board. Mine (Q770G4) boots on power, if I can organise some downtime with the family I’ll take a look at it (set it up ages ago so can’t remember).

Edit: CAB approval was easier than I expected! Mine is in the BIOS, under Chipset > PCH-IO Configuration, set State After G3 to Power On.
