  "rescue:grub> normal"

  GRUB2 doesn't boot karmic from raid1 device (md0). Instead it shows...

     GRUB loading.
     error: cannot get C/H/S values
     grub rescue>

  After invoking...

     grub rescue> insmod linux

  it shows...

                           GNU GRUB version 1.97~beta4

      [ Minimal BASH-like line editing is supported. For the first word, TAB
        lists possible command completions. Anywhere else TAB lists possible
        device/file completions. ]

     rescue:grub>

  where

     rescue:grub> normal

  boots the system (splash screen is shown after six to eight seconds
  and system boots).
