The reason that old BIOS proms make no difference fo rlarge drives is that
Under FreeBSD the bios is not used..
(I know I wrote the driver, ok?)

The board has NO IDEA what commands we are sending to the drive so
it can't possibly make a difference..

on booting teh bios is used, but if you never ask it to go far into the
disk
it never hits it's limit.
