Basically, your bios is performing an i/o port function which windowsXP considers maybe harmful - in short you need to go to the web page of your mother board manufacturer and download a program to upgrade your bios - upgrading your bios can be quite harmful if you dont do it properly - so unless you are having trouble with your computer because of this problem you are best to ignore it - if you still want to solve this problem and upgrade your bios i can help you do that - but be warned it can be dangerous.
