I just installed an areca ARC-1212 into my new Mac Pro and there's a weird problem with the setup process. When booting from the setup CD, it asks me to press tab or F6 to enter setup, or ESC to cancel. None of these keys work on this screen. If yo dou nothing, however, you get to a Knoppix splash screen that lets you press Enter to boot to Linux. The Enter key works here (though it takes me to a black screen rather than booting Linux). Do I need to find a Windows keyboard to these keys to work on that first screen?
