Boot up your system with DOS 3.1 from drive A, then transfer the
DOS's system files to C: by doing the followings:

-       From A, type:  sys c:
	after system files got transfer to C, do
-	Copy all DOS files from floopy A to the directory in drive C
where you have all the DOS files of the old version.
-	Check the "config.sys" and "autoexec.bat" to make sure all
device drivers and command syntax compatibility of the two versions.
-	Make sure the new "command.com" is replaced if you keep it
in the root directory.

Good luck!
