+ 1 Votes keyboard not responding when booting from cd rom jcv777 June 22, 2013 at 7:02pm PST I spent hours on this before coming up with the solution. It ended up all I had to do was disable support for usb devices in my bios, saved, restarted and boot from cd worked. I guess as long as your not using a usb keyboard, or some kind of usb rom device, or installing from usb your good to go. With usb keyboard support enabled in my bios, my ps/2 keyboard must have still been able to function? That's probably why someone elses solution was to reset the cmos, it reset to default? Don't know don't care all I know is that it was my solution. It makes sense now that I think about it.
