[Edit]Howto Prepare a USB MSD as Large Floppy for boot

1.  Are you sure you can wipe your USB Mass Storage Device?

2.  use DFSee  Version 8.11 or higher

3.  Look at the initial output of DFSee 

    Do you have the correct USB MSD to wipe?

4.  Mode Fdisk  
    main menu  Mode=Fdisk
    sub  menu  MBR area operations
    sub  menu  Wipe Start of disk to Zero 
    sel  menu  select line with your USB MSD   
    conf box   Confirmation request
  
               Are you sure the correct Disk to wipe? Check again !!?
 
    conf box   It is strongly advised to REBOOT the system now to allow it to determine
               the correct disk geometry and size. This may be required to 'see' the
               full capacity of the disk.
 
               OK 
 
5.  Exit DFSee, shutdown system, reboot  

6.  Start DFSee again               

7.  look at the generated list output to check last operation
  
     Check: 1.  L-Geo and size of your USB MSD   
   
            2.  No boot Record ! 
  
            3.  FreeSpace Pri/Log  for your USB MSD
  
8.  main menu  File  
    sub  menu  Open object to work with
    sub  menu  Disk
    sel  menu  select line with your USB MSD   

               Be aware:  DFSee will have selected Mode=FDISK here
                          because the disk is empty (wiped).

9.  main menu  Actions
    sub  menu  Format with FAT filesystem
    sel  menu  Current, OS2LDR.SEK bootable   
 
               Be aware:  DFSee switches from Mode=FDISK to Mode=FAT 
                          just before the confirmation box is displayed 
  
    conf box   Confirmation request
  
               Are you sure the correct Disk to format ? Check again !!?
  
               YES
 
10. generate list output to check last operation

    command line:    map -M -m

    F5 (part -r )
 
    ===>  --r C:  Large Floppy Format! FAT  OS2LDR.s   LargeFlopD2   xx MB     for your USB MSD
  
    Drive letter should be C:, if not, your configuration is not fit to boot from USB Large Floppy !!
 
  
    see paragraph "Restriction: no Drive Letter C: should be used by the LVM Volumes" !!!
 
11. exit DFSee
