I want to install a 200 GB WD HD in my Dell 8250. After reading Microsoft KBA 303013 here, http://support.microsoft.com/default.aspx?scid=kb;en-us;303013 , I know I need to update my Windows XP according to this article. What I don't know is how to find out if my AO1 BIOS I now have is compatible with this 48-bit LBA, which is required to use a hard drive that exceeds 137 GB. If not compatible what BIOS do I need? Thanks for your help.  Doogie
