Trouble updating Intel s2600cp Bios in Server 2008

I need some help updating the Bios on my Intel S2600cp2.  This is the first time I have used an actual intel board and my first time doing a full set-up of Server 2008 R2.  I am following the direction from intel regarding the installation of the flash update drivers on my 64 bit OS.  Then I go in and run the x86 flash update utility as directed.  Where I am stumped is when it tells me:
 
6. Now you can run command with options (example: "flashupdt -u /tmp/flashupdt.cfg").

I need help figuring out what this is.  I am a novice when it comes to code and DOS.  I have tried running this exact code through the run command but it just tells me it can't find the file referenced.  Please help.
