Drive spin up times should matter.  We haven't done a lot of booting
off of hard drives but we do know we can boot up faster than harddrives
can spin up.  I played with that a little the other day and I network
booted before a drive had spun up.

Ron when you wait for the harddrive to spin up what kind of boot times
are you seeing?

If he was thinking about linuxBIOS I can imagine how he would be confused.
But for any other case it doesn't seem to make sense.

But for with a normal bios I can't really imagine what he is talking about.

Boot Block flash just has some special features to make it easier to serve
as a BIOS ROM.  But I haven't seen anything about image validation, nor could
I imagine hardware doing it.
