   Thanks for responding.   
      
   The bios reports drive numbers in the order of what we call   
   sda,sdb,sdc...  I tried to add a drive map to grub but   
   it did not change the order.   
      
   When I get the grub menu, I can type c to get a shell   
   and do ls to see what the drives are.   
      
   The ordering is   
   hd0 sda   
   hd1 sdc   
   hd2 sdb   
      
   I can edit an entry and then the boot works.   
      
   It comes out this way even if I use the blockID   
      
   I know this sounds crazy.
