Hi Jeremy,

You made me spot a fatal mistake in what I did! I was thinking my floppy 
drive was A: - but it wasn't. As I said in my post, I was booting 
FreeDOS from CD-ROM, but that means A: is the emulation session of the 
CD-ROM, _not_ the floppy (duh!), the floppy (containing MD-DOS 6.22) 
would have been the B: drive!

So I should have issued


It probably still won't work, but at least I'll be using the correct 

Ultimately, what I want to do is use FreeDOS to transfer a saved MS-DOS 
6.22 boot sector direct to a FAT32 C drive; I've played around with the 
/OEM:MS switch in the past but couldn't get it to work. The purpose of 
this is to trick Windows setup into thinking it's upgrading from MS-DOS, 
otherwise it puts FreeDOS on a dual boot menu as my "Previous Operating
