Table of Contents
This file contains the following information concerning this release
of the TOPS-10 operating system.
2.0 List of files on the Auxilliary tape
3.0 Patch file installation
4.0 Patch descriptions
The purpose of this beware file is to provide field test information
that pertains to the contents of the Auxilliary tape for this load of
the monitor. Unless otherwise specified, the contents of this beware
file provides supplemental information beyond what is stated in
MONITR.BWR which is shipped on the field test tapes. There is one
important difference between the two beware files: MONITR.BWR is
intended to contain items of interest to all customers when the
product is released. AUX.BWR contains field test specific information
of interest to only the field test sites.
For the benefit of sites entering the field test at this time, some
information which had previously been presented in this document will
appear again. Be sure to read both beware files carefully.
2.0 LIST OF FILES ON THE AUXILLIARY TAPE
The following files are included on the Auxilliary tape:
1. AUX.BWR - Beware file for this tape.
2. 361KL.DDT - Patch file for KL10 monitors.
3. 361KS.DDT - Patch file for KS10 monitors.
4. CNFHDW.MAC - Corrections to CONFIG SHOW HARDWARE.

3.0 PATCH FILE INSTALLATION
This Auxilliary tape contains, among other things, two DDT patch
files; one for KL10 monitors and one for KS10 monitors. Before
applying any patch file, be sure to read its contents. Each patch
within the files will be preceded by a comment indicating the purpose
of the patch and what hardware or software options are required for
its installation. For example, in the KL10 file, the LDMP patch
indicates it is necessary to have FTCIDSK turned on. It may be
necessary to edit out certain patches which are not needed in your
Patch files are typically installed using the following procedure:
In the above example, "system" should be replaced by the name of your
monitor and "patch-file" by the name of your patch file name. While
other methods may be employed to patch a monitor, this one has been
used by us exclusively. The formatting of the destributed patch files
assumes this procedure will be used by the field test sites. No other
patch file formats will be distributed.
4.0 PATCH DESCRIPTIONS
This section details the reasons for the various patches contained in
the two patch files.
4.1 BAC STOPCODES AND CORRUPTED HISEGS
Occasionally, a BAC stopcode or a corrupted high segment will result
if the user's job is virtual and the some pages are write-locked by
the monitor. The user may notice the corruption after a save of the
corrupted core image. The corruption will usually appear as empty
(zero'ed) pages on subsequent GETs of the saved image. This patch
corrects the problem.
4.2 CHANGE STRUCTURE
If the CHANGE STRUCTURE option to the startup dialogue is used to
change the structure name, the corresponding HOMLOG entry is not
updated. This patch corrects the problem.

4.3 CI DISK FAILOVER
This patch corrects problems with CI disk failover caused by FILIO
setting the pack status in UNISTS incorrectly.
4.4 DVPHY. UUO
The DVPHY. UUO may fail to find DDBs following recent changes to the
ordering of the DDB chain. The affected DDBs are those for which
there is no prototype (in the AUTCON sense), but which do have an
INTTAB entry. This patch corrects the problem.
4.5 LOST IPCF ACKS
Occasionally, jobs get stuck in event wait for system IPCF for no
apparent reason. Some of them eventually take off again, some do not.
If the job for which the 'stuck' job is waiting does blocking IPCFR.s,
then there is a window after the point at which that job has decided
to give up and enter SL state, but before the sending job can tell
that, during which a packet could arrive and be ignored. If that
target job ever receives a second packet, it will process them both,
but the original job will wait until that time. This is most notably
seen inhouse with MX as the 'stuck' job and FILDAE as the target job.
4.6 SLEEP PROBLEM FOR RCNATC
This patch avoids IME stopcodes caused by the use of the
CONFIG AUTOCONFIGURE command. Calls to SLEEP clobber too many ACs.
4.7 UNL STOPCODES
This patch eliminates random UNL stopcodes which occur when virtual
jobs are being swapped.
There are some deficiencies in the HSC and/or the CI20 microcode which
confuses the monitor while performing large transfers on CI disks.
These problems cannot be programmed around. The LDMP patch breaks
down dump mode transfers in the hopes of not aggravating the disk
subsystem problems. This patch is not guaranteed to work, and has
minimal affects on dump mode transfers only. It has no affect on
buffered mode transfers. This problem has existed in previous

5.1 DTE Reloading
A problem exists in DTESER which necessitates the use of the /PROTOCOL
switch when reloading DTEs. Failure to include this switch on the
DTELDR command file will cause the specified DTE to be reloaded, but
it will not come online.
5.2 CNFHDW.MAC And ORNMAC.MAC
The changes in these files corrects illegal memory references in ORION
when the CONFIG SHOW HARDWARE command is used on a system without
internal channels or cache.
This file contains an updated version of the Software Installation
Guide. While it represents the latest revisions of the manual, it is
not complete. We would appreciate having the manual reviewed.
Comments and corrections may be returned via the QAR system.
The version of MONTAB.MEM supplied on the monitor save-set reflect
7.03 monitors. It contains no 7.04 information.
