I'm trying to boot into a CD. Unfortunately, I have to "press a key to continue" and my keyboard doesn't load/light up/start responding/etc. until after Windows starts. What can I do?
You can borrow a PS/2 keyboard or you can get a USB to PS/2 adapter.
Here is one from Amazon for $1.59 with free shipping. http://www.amazon.com/USB-to-PS-2-Adapter/dp/B00007AP2O
