I just don't think, in the overall scheme of things, considering how MUCH time we WASTE in other areas, that shaving four seconds off your boot time is something that needs to be extolled as a priority or is something of great importance to the masses.
I mean, sure, I can see that four seconds faster boot time being really important to somebody that is in a hurry to get into their browser so they can go spend five hours on Youtube trying to figure out why they aren't getting a bazilliony FPS on Minecraft or finding that purrfect cat video. Everybody else, knows it's going to take however long it takes, and will mostly use sleep anyhow.
For overclocking, this isn't going to apply anyway because traditional POST times are not going to be applicable in instances where training and auto reconfiguration are applicable due to user changes anyway. Overclocking, if you're doing it right, is a fairly long process anyway. Saving 160 seconds in a day's worth of experimentation doesn't REALLY seem to be an area of emphasis to me, and I'm an overclocker. I'd rather see the resources put into areas of the BIOS that might actually HELP with overclocking or stability or compatibility, not saving two seconds between trips to the setup program.
