Thanks for your time.
man boot has this: boot.conf processing can be skipped, and the automatic boot cancelled, by holding down either Control key as boot starts. and as that's where the "set tty com0" command is, that will solve your problem. (I can rarely remember which key it is, so I often just hold down CTRL, ALT and SHIFT on one side of the keyboard.) (note: I'm assuming you are talking about amd64 or i386 platforms). Nick.
