@SimpleTECH, when I tried out the F8f BIOS for my UD5, I wasn't able to use my keyboard neither.. well, I could enter the BIOS, but whenever my system reset itself, or didn't shutdown properly, when the screen that comes up asking if you wanted to boot into safe mode, or start windows normally, I was unable to choose the option I wanted, and I had to let the timer countdown before I could enter the OS...
It is really annoying, because on F7 BIOS my keyboard works fine, but the PWM fan control doesn't work so the fan on my cooler runs at full speed all the time, but on the F8f BIOS PWM fan control works perfectly, but my keyboard doesn't work after the system POSTs..
Not that you maybe havent guessed it, but have you checked in bios? there is an option that you can enable usb keyboad, if that is disabled, you get that you cant use the keyboard after post..
