Removing boot options and setting boot only to BSD

[Viswas Nair]

I have FBSD 6 and Win XP on my machine. I would like to remove the boot menu
options that I get and set BSD to open default. How do I go about doing this
? I intend to use Win XP very rarely and hence would want to manually update
the config files needed if I need to go to Win XP.

Thanks.
