I'm trying to switch to a usb keyboard. It works perfectly in linux, but in the grub menu, I have no keyboard. So I find an option in my BIOS that says enable USB keyboard support, turn it on, and grub works perfectly, but now linux doesn't see the keyboard. Is there any combination that will let both grub and linux work at the same time :-). I see some gibberish in the BIOS about "gate A20" with options that read kind of like "Do you walk to school or carry your lunch?", perhaps it also needs to be set just right for both to work?
