According to the following link from IBM, the process we are both 
thinking of is valid, just using different files.

Ya.  MS-DOS < 7.x doesn't understand FAT-32 drives.  -  I think there 
are drivers that you can load to add support for it.  Or you can just 
use MSDOS.SYS, IO.SYS, and COMMAND.COM from Windows 9x.
