+Boot from the PC-DOS 7.0/2000 floppy and partition your drive as needed.
+Make sure you 'sys' the drive using //format /s//
 //Warning: I found that formatting a FAT32 partition was not supported and had to do that on another system, though the formatted partition did actually show up fine after being created on another system.//

+==== Add PC-DOS 7.1 System Updates ====
+Get a copy of the newer PC-DOS 7.1 files (they are under 1MB in total) and copy them to a floppy disk under a PCDOS71 folder.
+=== Removing PC-DOS 7.0/2000 Files ===
+<code>
+Delete the 7.0/2000 system files (IBMBIO.COM, IBMDOS.COM, COMMAND.COM) from the formatted hard drive:
+A:\>ATTRIB -S -H -R C:
+A:\>DEL C:\*.*
+</code>
+=== Install PC-DOS 7.1 Files ===
+<code>
+Copy the 7.1 system files to the C: drive. //Make sure you do it in this order!//
+A:\>CD PCDOS71
+A:\PCDOS71>COPY IBMBIO.COM C:
+file(s) copied
+A:\PCDOS71>COPY IBMDOS.COM C:
+file(s) copied
+A:\PCDOS71>COPY COMMAND.COM C:
+file(s) copied
+</code>
+=== Add a DOS Folder ===
+<code>
+Create a DOS directory on C: and copy the 7.1 files into it:
+A:\PCDOS71>MKDIR C:\DOS
+A:\PCDOS71>COPY *.* C:\DOS
+   ...
+XCOPY.EXE
+file(s) copied
+</code>
+You should now have a formatted PC-DOS 7.1 partition with just the new PC-DOS 7.1 system files in C:\DOS.
