Fedora Installation :: New 11 Install - Press The "enter" Key To Begin Doesn't Work

I have a new Dell R710 dual processor machine I'm trying to install Fedora 11 x86_64 on (all versions I mention in this post are x86_64 bit). I downloaded the cd iso files, burned them to cd (I don't have a DVD burner), then told my machine to boot to the optical drive.

I get a very brief introduction message about ISOLINUX then the monitor refreshes and gives me the following message: "Press the <Enter> key to begin the installation process."

Naturally, I press the Enter key(s) on my keyboard. Nothing happens. I try Alt ASCII combinations that might mimic an Enter key. No dice. ctrl-alt-delete works, however, and the machine reboots.

My checksums for the iso's are perfect, and the install process triggers perfectly on other machines. Just not this one.

After much vain research, I download the Fedora 11 Live-KDE, burn it to CD and try it. It doesn't work - the same thing happens. I tried the net install, and it doesn't work either.

On a lark, I download the Fedora 10 Live KDE iso and burn it to cd. It works perfectly and skips the "Enter" phrase entirely. I take my Fedora 11 Live KDE disc and put it in another machine and it, too, works perfectly, which leads me to believe my cd burns are fine.

I've also used usb creator to create a bootable USB drive. It doesn't ask me to press enter - it just fails with a really arcane IF=0 error (arcane to me, anyway).

So I'm at a loss. I'd like to install Fedora 11 on this machine, but may end up with Fedora 10 or CentOS if I can't figure this out.

Is there some weird BIOS setting somewhere I'm missing? I find it really weird that my fedora 10 cd works, but my fedora 11 cd does not (but my fedora 11 cd works in other machines).
