Hi all ,

2.6.11.7)
   This morning  , the server display message in the monitor :

           "EXT fs-2 error xxxxxxx"

  I did not what happened suddenly have the error message.
  When i had rebooted the server , the fedora core 2 cannot boot up.
  It display error message below :
           "Operation system not found "

  Anybody have any ideas and suggestion to solve this problem ?
  Can i rescue my Fedora box ?

Thanks
