Averatec 3120V reinstall of winXP pro sp2

Question

Hi I am trying to do a fresh load of xp pro sp2. I get part into the install and it is asking for files which I believe to not reside on the standard Win XP 2 cd. I'm looking to get drivers, etc that apply to this pc.also a current bios update as well.I don't want to use driver detective or any pay site I just want to get what I need from the manufacturer . Thanks Lou
