I get a critical battery warning error during the runonce portion of my server 2k3 install. I can install my modded XP off the same iso (eliminates the image) clean with no battery warning. When I install on a physical drive there is no warning (eliminates the first piece of software in the runonce), so I keep leaning back towards it being a product of the Vbox.

So anybody else have an issue with virtualbox throwing erroneous critical battery errors, or any idea of what I am missing?

Are you running this off from a laptop? I have used virtualbox before, and always have problems.
