This README file accompanies the FIXOPEN.NLM patch file for NetWare 386 v3.10
Rev A. The following file is included for this patch:

FIXOPEN NLM 2708 08-29-90 4:51p
PATCHMAN NLM 3005 08-29-90 10:38a

FIXOPEN is a dynamic patch that is loaded at the file server console as a
NetWare Loadable Module. This patch fixes a problem in NetWare 386 v3.10a
that would not allow files that were flagged RO to be opened with RW rights
when the Read Only Compatibility mode of the shell was on. This problem was
seen in an application as an error: "File not found" or "Access denied."

Read Only Compatibility = Off is the normal mode of operation and requires
RW rights for applications which open in RW mode. The Read Only
Compatibility parameter in the shell is intended to allow such applications
to open a file when the user only has RO rights.

In order for FIXOPEN to work correctly, it is necessary for the workstations
to be using v3.01 Rev. C of the NetWare shells (NET3.COM or NET4.COM). These
shells have been modified to accommodate the changes implemented by FIXOPEN.
Without this version of the shell, the Read Only Compatibility will have no
effect, allowing any file that is flagged RO to be opened with RW rights,
thus compromising the additional rights security implemented in NetWare 386
v3.10a.

To implement this patch, the NetWare 386 Patch Manager (PATCHMAN.NLM) must
first be loaded.

Three types of patches can be managed with PATCHMAN: dynamic, semi-static,
and static. Dynamic patches are .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 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. A
static patch is a DOS executable program that makes changes to the SERVER.EXE
file. This type of patch is applied once and its effects are permanent. It
is suggested that static patches be applied to a copy of the SERVER.EXE file,
not the original file.

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 " be placed in the
file server's AUTOEXEC.NCF file to ensure that the patch is always in effect
when the server is initially brought up. 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
.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.

To implement this patch:

1) Copy PATCHMAN.NLM and the patch .NLM file to the same directory as the
other NLM files on your system (SYS:SYSTEM is suggested).

2) After the system is brought up, type LOAD PATCHMAN at the console.

3) LOAD the patch .NLM file.

NOTE: 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.
