Is there timeout string on the screen? Is there any USB device conntected? I'm under impression that BIOS "interprets" one of their input as keys.

On a Dell Dimension 4600 with the (latest) A12 BIOS, with HyperThreading enabled in the BIOS and the USB Emulation option enabled (by default), grub2 in Fedora 18 (grub2-2.00-15.fc18.i686) reaches the boot selection menu but then freezes up and won't respond to any keys. Disabling either HT or the USB Emulation option results in grub2 working normally. Presumably USB Emulation is needed to use a USB keyboard in the boot menu, however.
