Keyboard not responding on Grub: solution

These days I have been trying to install openSuSE to play around a bit. However, I have found an apparently impossible difficulty: when I tried to boot with the openSuSE DVD my USB keyboard was not responding.

The usual workaround is to configure the BIOS so that USB works in legacy mode, or to use a PS/2 keyboard. None of these solutions were applicable to me, as I was trying to install SuSE on a Dell model XPS-210, which doesn’t have a PS/2 connector and whose BIOS doesn’t have the right option.

My workaround has been to just update the BIOS.

I’m pretty sure that this update solves other similar issues with many Linux distributions using Grub, like Kubuntu.
