Well, I broke it! FreeBSD V8.1 release

[Dave]

Hi...

I was trying to disable the console screensaver, and found that in 
sysinstall, there is no way to select "none" as an option.

So I went and edited /etc/rc.conf to comment out the line:-
Saver="fire" (or whatever it is)

I put a ; at the beginning of the line, and now FreeBSD wont come up, 
showing an error (unexpected ;) and leaving me with a # prompt.

How do I get to re-edit rc.conf, to correct the problem, as all command 
line commands result in a "not found" error.

Also.  What's the "Correct" way to disable a console screensaver?

Sysinstall alows you to select and enable one, but not remove it!

Bit of an oversight that I suspect....

Regards.
