can t use keyboard during install

I can't use my keyboard during the installation. I can't get any further then the activation part. My mouse works though. The keyboard is USB, my computer does not have any PS/2 ports. I tried another keyboard but it didn't help.
System specs:
Motherboard: Dell Dimension 9100 BIOS: Phoenix Tech (05/25/2005) Chipset: Intel Lakeport i945P CPU: Pentium D 830 (3GHz, 800FSB) RAM: 2GB DDR2 533MHz (4x 512MB DIMMs)

I figured it out on my own. I used a Targus USB Port Replicator and an old PS/2 port Keyboard. Vista does not reconize my USB Keyboard (Dell keyboard) even after installing and running the OS.
