This patch repairs a mirroring bug in the sft code of NETWARE 2.15X. The
patch allows the remirror command to copy VIT sectors 22-25 in addition to
the usuall sectors 16 and 17.  The problem is only present on large drives
(600 Meg).

The programs and data in this subdirectory are for patching the net$os.exe
or the net$os.ex1 file.  Use the following procedure:

Before you do anything, be sure all data on the server is backed up.


1) Login as supervisor to the server to be patched and change to the
subdirectory sys:system.

2) Use the FLAG program to set the attributes on net$os.exe to read/write:

          flag net$os.exe rw

4) Copy the files on this floppy to sys:system.

5) Type the following:

          pexe net$os.exe <cr>

4) It will take about 10 seconds for the patches to finish and a message
will come up indicating if the patches were successful or not.

5) An alternative method, is to leave the patch programs in one area and
put a path on the filenames to be patched above.

note: Note the net$os.ex1 file in the netgen area can also be patched
before it is installed by netgen.  If you do this type the following.

          pexe net$os.ex1 <cr>

6) When finished, verify that the modify date has been changed and copy the
newly modified net$os.ex1 back to its area in the netgen subdirectory.  Or
if you modified net$os.exe in sys:system, change the file attributes back
to read only by typing "FLAG NET$OS.EXE RO".

WARNING:  THIS PATCH WILL NOT WORK ON OBJ FILES.
