So I recently started using a Das keyboard ultimate with my mac and after installing the key re-mapping, it basically works ok.

I have a couple of issues with the set up involving boot camp.

1. When I start up the computer, which key maps to option in order to let me pick which operating system to boot into? I think the bios is detecting the keys along the bottom as alt or something like that and I am not sure what to do here.

2. In windows 7, the " and @ keys are switched. How do I get windows to remap this back to the US english settings?

Thanks for any help you can provide.
