Skipping "F1 FreeBSD" prompt on boot

[David Landgren]

List,

I have a disk that has only FreeBSD on it, and so I would like to skip 
the initial F1/FreeBSD prompt. boot0cfg -v ad0 says:

options=nopacket,update,nosetdrv
default_selection=F1 (Slice 1)

... what do I have to do to say JFDI instead of prompting? This is not 
the sort of thing I want to fiddle around experimenting, so a little 
guidance would be most appreciated.

Thanks,
David
