are included for this revision:

PATCHMAN.DOC (This file)
This version of PATCHMAN replaces any and all previous versions of
PATCHMAN. PATCHMAN v2.01a can only be used with NetWare v3.11+.
NetWare v3.10a requires PATCHMAN v1.20b.

PATCHMAN.NLM is the Patch Manager for which tracks and manages all
official patches for NetWare 386 v3.10+.
Patches for NetWare 386 v3.10+ 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.
The Patch Manager (PATCHMAN.NLM) must be loaded before any dynamic
or semi-static patches can be loaded. If PATCHMAN is not already
loaded, the <patch>.NLM will attempt to locate PATCHMAN and, if
found, will load it automatically. PATCHMAN only needs to be
loaded once; all .NLM patches can then be loaded. PATCHMAN cannot
be unloaded until all patches that rely on it are first unloaded.
