PM312.NLM replaces any and all previous versions of
PM312.NLM.  

PM312.NLM is the Patch Manager which tracks and manages all
official patches for NetWare 386 v3.12.

Patches for NetWare 386 v3.12 consist of three types: 

     DYNAMIC -- Dynamic patches are implemented as .NLM files that
     can be loaded/unloaded while the server is running.  Unloading
     a dynamic patch will restore the Operating System to its
     original "un-patched" state.  

     SEMI-STATIC -- Semi-static patches can also be loaded while
     the server is running, but they cannot be unloaded.  It is not
     possible to undo the effects of a semi-static patch without
     first downing the server and bringing it back up without
     loading the semi-static patch.  

     STATIC -- A static patch is a DOS executable program that
     modifies the SERVER.EXE file.  This type of patch is applied
     once and its effects are permanent.  It is suggested that a
     backup of the original SERVER.EXE file be made before applying
     a static patch.  (In other words, do not patch the SERVER.EXE
     on your original distribution diskette!)

Dynamic and semi-static patches modify the Operating System in
memory, not on the disk.  This means that dynamic and semi-static
patches must be loaded each time the Operating System is brought up
in order for any 'fixes' to take effect. It is recommended that the
command "LOAD <patch>" be placed in the file server's AUTOEXEC.NCF
file to ensure that the patch is always in effect as soon as the
server is brought up.

In order to see which patches are currently loaded on the system,
type "PATCHES" at the file server command line.  The patches will
then be grouped and displayed according to their type (i.e. -
STATIC, SEMI-STATIC, or DYNAMIC).  Typing "MODULES" at the server
console will show which dynamic patches have been loaded, but will
not show semi-static or static patches.
  
To install PM312.NLM, log into the server as supervisor or
supervisor equivalent and copy PM312.NLM into the SYS:SYSTEM
subdirectory.  The Patch Manager (PM312.NLM) must be loaded before
any dynamic or semi-static patches can be loaded.  If PM312 is not
already loaded, the <patch>.NLM will attempt to locate PM312 and,
if found, will load it automatically.  PM312 only needs to be
loaded once; all NLM patches can then be loaded.  PM312 cannot be
unloaded until all patches that rely on it are first unloaded.
