This README file accompanies READFIX.NLM for Netware v3.10 rev.A. The
following files are included for this revision:
READFIX.NLM 721 2-5-91 9:58am
READFIX.DOC (This file)
PATCHMAN.NLM 6550 2-5-91 10:16am (V 1.20b)
PATCHMAN.DOC 3634 2-7-91 10:10am
READFIX is a dynamic patch which is loaded at the file server console as a
NetWare Loadable Module. This patch fixes a problem in NetWare 386 V3.10a
that could cause an invalid error code to be returned to an application
making a file READ operation. This problem was first noticed using the
BTRIEVE NLM.
READFIX requires the latest version of PATCHMAN.NLM (v1.20b) in order to load.
Unlike previous patches, the SERVER.EXE file is never modified by this patch.
READFIX.NLM patches the Operating System in memory, not on the disk. This
means that READFIX must be loaded each time before any "fixes" take effect.
It is recommended that the command "LOAD READFIX" be placed in the server's
AUTOEXEC.NCF file to ensure that the patch is always in effect when the server
is initially brought up.
Since it is an NLM, READFIX can be loaded and unloaded without ever having to
bring the server down. Once loaded, the Operating System is patched and ready
to go. Unloading READFIX will restore the Operating System to its original
"un-patched" state.
Like all NLM-type patches, READFIX requires the Patch Manager (PATCHMAN.NLM) to
be loaded before it can be loaded. If PATCHMAN is not already loaded, READFIX
will attempt to locate PATCHMAN and load it automatically if found. PATCHMAN
only needs to be loaded once. All other patches can load once PATCHMAN is
loaded. PATCHMAN cannot be unloaded until all patches that rely on it are
first unloaded. Typing "PATCHES" at the system command line once PATCHMAN is
loaded will display all patches currently loaded on the file server.
To install READFIX:
1) Simply copy the READFIX.NLM and PATCHMAN.NLM in the same directory as
the other NLM files (SYS:SYSTEM is suggested).
2) Type "LOAD READFIX" at the console. A message will appear saying
that the OPERATING SYSTEM has been successfully patched. From this
point on, all changes are in effect until READFIX is unloaded. If
an error message appears, contact your Netware support provider.
The changes made by this patch will be implemented in all future versions of
NetWare 386. This patch and PATCHMAN.NLM will only operate on NetWare 386
V3.10a. Future versions of NetWare 386 will require a version of PATCHMAN
specific to that release.
