Syed,
I would also look into this utility, [url]http://en.community.dell.com/techcenter/systems-management/w/wiki/1952.dell-client-configuration-toolkit-cctk.aspx[/url]. We run the full Latitude lineup where I work, this is what I use when I need to make changes “enterprise” wide to machines. I package BIOS settings with this utility and push them out through our deployment software. (Unfortunately, it’s not FOG).
