CPU won't start up after setting Shared Memory Size

[mkkingwell]

I was messing around in the settings when you press DELETE at startup (the dos-type screens) and I set my "Shared Memory Size" to 0. Then I went to restart and it starts up to some colored screen. Where I can't do or see anything. I tryed pressing ESC or Return and nothing happens. Every key I press it alternates to a different color.

I am on my friend's computer right, does anyone know what I did? And is that the end of my computer?

Reset CMOS or hold the insert key while starting. The insert key may take several attempts but usually works.
