There is one other issue and that on older boards you may find it impossible to setup the BIOS without the PS2 keyboard. There is another issue with USB keyboards and that an incomplete install of Windows is known to crash if the motherboard drivers are not installed. Again, the PS2 keyboard saves the day as you can get back in, finish the install and then let them have their USB keyboard back.
What do I use on my homebuilts? All are PS2 save a very special little server.

I have a question.
What's the difference between a keyboard that uses PS/2 and one that uses USB?
The only difference that I could find is that PS/2 aren't designed to be "hot swappable."
This means that you shouldn't remove and replace a keyboard using a PS/2 while the computer is still operating.
On the other hand, with a USB, you can apply such "hot swapping" method.
Am I correct about the "hot swapping" properties and are there any other difference between a keyboard that uses PS/2 and USB?
Thanks.
