1. Testing various configurations of GRUB and the booting of multiple Operating Systems.
2. As a recovery diskette when GRUB has been destroyed by that 'other' Operating System.

The following assumes that you are using Caldera eD2.4 and that all GRUB components are kept in the /boot/grub directory.

Note: The /etc/grub.conf file is used only to install grub and is not used by grub directly. We will create a new version of this file.

1. Format a floppy disk in FAT format:
   
   mkfs -V -t msdos /dev/fd0 <== use fd0 or fd1 as appropriate
   
   
2. Mount the floppy:
   
   mount /dev/fd0 /mnt
   
   
3. Create a boot directory and a grub directory on the floppy:
   
   mkdir /mnt/boot
   mkdir /mnt/boot/grub
   
   
4. Copy all files from /boot/grub to the floppy:
   
   cp -pa /boot/grub/* /mnt/boot/grub
   
   
   
5. Unmount the floppy disk:
   
   umount /mnt
   <now we modify the /etc/grub.conf file to install grub on the floppy>
   
6. Make a copy of /etc/grub.conf and call it: /etc/grubfd.conf:
   
   cp /etc/grub.conf /etc/grubfd.conf
   
   
7. Edit the new /etc/grubfd.conf file to look as follows:

   #                                                                                          
   # /etc/grubfd.conf - make a floppy boot disk                                               
   #                                                                                          
   # To install grub on the floppy, issue the following command:                              
   #  grep -v ^# /etc/grubfd.conf | grub --batch                                              
   #                                                                                          
   root (fd0)                                                                                 
   install /boot/grub/stage1 d (fd0) (fd0)/boot/grub/stage2 0x8000 p (fd0)/boot/grub/menu.lst 
   quit  
   

8. Install GRUB on the floppy disk:

   grep -v ^# /etc/grubfd.conf | grub --batch
   
   
       GRUB  version 0.5.94  (640K lower / 3072K upper memory)                                        
                                                                                                      
    [ Minimal BASH-like line editing is supported.  For the first word, TAB                           
      lists possible command completions.  Anywhere else TAB lists the possible                       
      completions of a device/filename. ]                                                             
                                                                                                      
   grub> root (fd0)                                                                                   
    Filesystem type is fat, using whole disk                                                          
                                                                                                      
   grub> install /boot/grub/stage1 d (fd0) (fd0)/boot/grub/stage2 0x8000 p (fd0)/boot/grub/menu.lst  
                                                                                                      
   grub> quit
