I'll bet you a nickel the 'wine error message "unknown DOS version"' is
not not not not a wine error.  It is a typical DOS application
complaint.  I don't have one with that exact error message, but would
you believe "Incorrect DOS version" is a symptom of the same problem?

Let's try using debug.exe from MSDOSE sick.tutu to read a copy of an
MBR:

[whit at giftie windose]$ wine debug.exe mbr
Warning: unprotecting the first 64KB of memory to allow real-mode calls.
         NULL pointer accesses will no longer be caught.

Incorrect DOS version
[whit at giftie windose]$ wine --winver win31 --dosver 6.22 debug.exe mbr

In case you missed that, it is spelled

wine --winver win31 --dosver <x.yy>

where x.yy is the DOS version your app wants to see, FI 6.22 or 3.01
