I'm measuring from bios handoff.
A modern bios takes between 1 and 2 seconds (if yours takes more, talk to your hw vendor...).
I'm personally not convinced that coreboot is fundamentally faster than a decent bios; the long time taking tasks are shared (bringing up/discovering memory etc etc)....

I've never had a BIOS that fast :-(
Actually I think most of my BIOS time is spent enumerating SATA devices, which takes *bloody ages*.
Do you have any recommendations on what (consumer-level) hardware to get which is known to have a decently fast BIOS - or know of anywhere that bothers to document that sort of thing?

How about replacing the BIOS?

you can configure most BIOS to not do autodetection of drives, that can drasticly speed up the system.

Sadly this board has two SATA controllers, and one of them doesn't seem to be controllable via the main BIOS except to disable it, plus it seems that the only way to disable autodetection is to enable PATA emulation mode.
This is all the sort of thing that doesn't tend to get mentioned in motherboard reviews, which is why I'm interested in any resources that do check and give that information.

Hmm, then how about this DG945GCLF that I have here, that with absolutely nothing attached takes 10 seconds to tell me there is no boot device.
