If you happen to use Dell computers I think they offer some ways to do this remotely. Check here for more info http://www.delltechcenter.com/page/Dell+Workstation+Bios+Configuration John Marcum | http://myitforum.com/cs2/blogs/jmarcum |

As John eludes to, this a hardware specific task outside of the scope of an OS management tool (like ConfigMgr) or even the OS itself and you must thus use tools and techniques provided by the hardware vendor to accomplish this task. Good vendors (like Dell typically is), provide you with tools to do this.Jason | http://myitforum.com/cs2/blogs/jsandys | http://blogs.catapultsystems.com/jsandys/default.aspx | Twitter @JasonSandys
