I'm pretty sure it's stored in NVRAM - the display gets initialized ( at le=
ast when you enter the OF prompt ) long before there's any disk activity. O=
f course MacOS sometimes likes to switch resolution when booting ( and even=
 does that pretty early ). OF prior to 2.0 doesn't preserve this informatio=
n at all so MacOS sets it and it's 'forgotten' when you boot something else=
 :)

have fun
Michael
