SYMPTOM
(02/22/95) ASSIGN.COM (1.05)
Both utilities no longer display invalid (beyond LASTDRIVE) drives
as assigned/substituted.
SOLUTION
Overwrite the ASSIGN.COM file in the NWDOS directory with the new ASSIGN.COM.
SYMPTOM
CHKDSK is not compatible with Stacker 4.0 drives.
(05/08/95) CHKDSK.EXE (1.21)
/B option should now disable all prompts.
If /WP was specified the system would crash in some situations after
CHKDSK terminated and the next app was started.
An invalid pointer was used when Stacker was not found which could
occasionally hang the machine.
SOLUTION
Overwrite the CHKDSK.EXE file in the NWDOS directory with the new CHKDSK.EXE
file. This version of CHKDSK.EXE includes a /NS command line parameter to
instruct CHKDSK to not do internal Stacker checking on a Stacker 4.0 drive.
SYMPTOM
(09/13/94) COMMAND.COM
Using copy on the POWERLAN 3.1 network now works correctly. Has TRUNAME
support which refers to command/path handling.
(01/23/95) COMMAND.COM
Has TRUENAME help support which refers to command/path handling
Removed closing handles 5 and 6 during abort from critical error or INT23
Enabled semicolon(;) to start a comment in a batch job
SET now removes leading blanks, commas, semicolons and equal signs, but
keeps blanks in the variable name (not only in the value).
Changed critical error message dispatcher
Enabled UNC filenames for file processing command. This requires VLMs
dated after Oct 07 1994. There are some limitations when using this on PNW:
a) PNW does not support a primary server (thus if the current drive
is not a PNW drive you can't access some default server without
specifying the server's name).
b) PNW does not support accessing a volume on a server where no
drive/port is mapped/captured to.
c) Accessing \\SERVER\VOLUME with an invalid VOLUME succeeds partially
Made renaming possible for all kinds of directory specifications for the
destination (eg. \, dir\, dir, ..) - worked previously only for DIR
Disabled interpretation of single ! in if condition
(02/17/95) COMMAND.COM
OR within an IF statement was not working.
Command extensions through INT 2F AX=AE01 could return a zero size
command which was still processed. (03/21/94)
(05/08/95) COMMAND.COM
LOGIN_NAME, P_STATION, and STATION pseudo-environment variables
work now without NETX being installed. FULL_NAME however has not
been converted due to the large amount of changes that would
be required here. This makes LOGIN_NAME now working on PNW given
that the current drive is a PNW mapped drive.
In low memory situations a temporary buffer was not freed preventing
commands from succeeding which require memory (mainly COPY). This
addresses a problem with CoorsLink.
SOLUTION
Overwrite the COMMAND.COM file in the root directory with the new COMMAND.COM.
SYMPTOM
(03/21/95) DEBUG.EXE (1.41)
DEBUG no longer destroys root mappings whe started with remote
drive being current.
(05/08/95) DEBUG.EXE (1.42)
I and O commands (in enhanced mode) now support ports outside the PC
range (>=0400h) and size specifiers B, W, and D (the last only on
386+ processors).
SOLUTION
Overwrite the DEBUG.EXE file in the NWDOS directory with the new DEBUG.EXE file.
SYMPTOM
(03/16/94) DPMS (1.1)
DPMS fixes minor problems from the original shipping version.
Note: This vesion may cause a problem with PKUNZIP 2.04g
causing a reboot with DPMS, NWCACHE and (DPMI=ON
and/or MULTI=ON). The temporary workaround is to use this
an older version of DPMS *or* turn off MULTI and DPMI.
Engineering is aware of this issue and is working on a solution.
(9/21/94) DPMS (1.2)
DPMS is incompatible with 386MAX when 386MAX has been configured
with the EMS=0 option. DPMS has been modified to inform the user
to reconfigure 386MAX to use the NOFRAME option instead.
(11/15/94) DPMS.EXE (1.3)
fixes a machine reboot problem seen when MULTI and DPMI are
enabled, NWCACHE is loaded and PKUNZIP is executed.
(01/23/95) DPMS.EXE (1.4)
INT 67 calls are made if running Windows in enhanced mode and
EMM386.EXE's multitasking support is not enabled. As a result
of these changes, code to restore 0E's entry in DPMS'
IDT when quitting Windows should have been removed
and this has now been done.
(02/23/95) DPMS.EXE (1.41)
Reduced memory requirements when running under XMS on 386.
SOLUTION
Overwrite the DPMS.EXE file in the NWDOS directory with the new DPMS.EXE.
SYMPTOM
(07/12/94) EMM386.EXE
This version has a fix to enable CodeView 4.1 to work when DPMI
is enabled. There is still an outstanding problem which occurs
when DPMI is set to OFF and this will be addressed at a later stage.
Other fixes:
o NE2100 causing a DMA failure
o problems with second DMA controllers on ps/2 & comptabiles using
channels 5,6 or 7
(08/10/94) EMM386.EXE
This version of EMM386 fixes a problem with Borland C++ v4
whereby if the multitasker was loaded VCPI memory would not be
freed after BCC32 had been run.
(10/03/94) EMM386.EXE (3.04)
The fix for the DOS 4GW problem. EMM386 now has a new command line option
PIC=ON/OFF if it is set to on VCPI apps will be told the PIC has not been
revectored. Please note that it must be set to OFF for normal operations. It
seems to get all the games working on the single tasking EMM386 but a couple
still fail on the multitasking EMM386 (DOOM 1 and RAPTOR are the two that we
are aware off) If you are running on the multitasking EMM386 DPMI must be off.
The help screen will give full details. A batch file which does the following
before the game is started is recommended:
DPMI OFF
EMM386 PIC=ON
This will set EMM386 and DPMI correctly for games to run.
(10/03/94) EMM386.EXE (3.05)
This fixes a screen corruption problem with the Dell Latitude
when running on the multitasker.
Help put in for NOEMS and NOVCPI. PIC state displayed if changed.
EMM386.EXE 3.07
Both multi and single tasking memory managers had a memory
allocation problem (crashing of the VLMs at load) on EISA machines
having more than 16Mb. Master Of Magic (MicroProse) did not run.
IP is now correctly updated when instructions that cause a GP fault
are traced in a debugger. Accessing DRx registers with DPMI and/or
MULTI turned on (CodeView 4.10) is now possible.
Resizing an XMS block from 0 to a positive size is now possible
under EMM386 MULTI. A problem with this was observed with the
FlashTek DOS Extender. (03/21/95)
Fixed problem with Borland 3.1 IDE debugger. (03/23/95)
(05/08/95) EMM386.EXE (3.08)
Borland's TDX will now work with DPMI=ON.
WordPerfect 6 for DOS will now work on PS/2 machines.
Fixes a problem with DBase 5 rebooting computer.
SOLUTION
Overwrite the EMM386.EXE file in the NWDOS directory with the new EMM386.EXE.
SYMPTOM
(05/08/95) FILELINK.EXE (3.01)
FileLink would display garbage if more than 1000 directory entries
were found in one directory.
FileLink could occasionally appear to hang during file transfers.
SOLUTION
Overwrite FILELINK.EXE in the NWDOS directory with the new FILELINK.EXE
SYMPTOM
(05/10/94) HIMEM.SYS
fixes EMS page frame problems.
(03/29/95) HIMEM.SYS
Fixed problem with corruption of excluded memory.
SOLUTION
Overwrite the HIMEM.SYS file in the NWDOS directory with the new HIMEM.SYS.
SYMPTOM
(08/01/94) IBMDOS.COM
IBMBIO.COM
SHARE.EXE
New IBMDOS and IBMBIO files, fix a problem with VM Boot, where a
program called FSFILTER.SYS is installed, taking over INT 21.
This does not return the SETVER value in AX, so the version
number we get back is invalid. The SETVER version is now poked
into the PSP during the INT 21 call, so if something takes over
INT 21 we do not use the return value as the version number.
Fix to IBMDOS.COM and SHARE fixes a problem where files that were
open on a PNW server could be renamed by a client.
These files are rebuilds, and contain all previous fixes.
***THESE THREE FILES (IBMBIO.COM, IBMDOS.COM AND SHARE.EXE MUST
BE USED TOGETHER - DO NOT MIX WITH OLDER VERSIONS***
Other fixes:
o Accesing a Stacker 4.0 volume would cause EMM386 protection errors to occur
if users had Stacker 4.0 on their hard disk before installing Novell DOS 7.
(3/18/94)
o A double \\ appearing with NetWare 4.x LOGIN.EXE (3/25/94)
o The system sometimes reads beyond the end-of-chain when corrupt directory
entries are encountered.
o The key combinations of ALT-T and ALT-Q not working correctly with the
Colorado Tape Software.
o Problem initializing DCA's IRMA 3270 emulation software. (6/7/94)
o Unable to start a DOS session under OS/2 due to SETVER returning an invalid
version number.
o SETVER returning an invalid version number during a VM boot in which a 3rd
party device driver takes over INT 21.
o Accessing a network path greater than 66 characters when using VLMs. After
trying to to CD, TREE, XDIR, XDEL, etc. the drive mapping appears to be
invalid. (10/06/94)
o Fixed a problem when remote booting where an attempt was made to load the
NWDOS.386 VXD. This fix stops the attempted loading the NWDOS.386 VXD, which
is no longer needed, as it could not be loaded after a remote boot process.
(05/08/95) IBMBIO.COM
INT 2F AH=13 no longer destroys AX (VGACopy crashed due to this).
'SC' memory block signatures are now applied correctly.
DRIVPARMed 1.44Mb drives can now be formatted correctly.
DRIVPARM can now be used for 2.88Mb drives as per doc.
Size of driver to be loaded high now calculated correctly if .EXE
file.
Ctrl-F5 and Ctrl-F8 are now treated the same way as F5/F8 (MS-DOS 6.2
does so).
Keyboard interface now uses enhanced functions on enhanced keyboards.
2.88Mb floppies are now correctly detected even if they are reported
as type 04 instead of 05/06 from BIOS.
Atari floppies can now be read.
FASTOPEN now defaults to 0 as MS-DOS does.
HIINSTALL does no longer prevent correct assignment of MCB owners for
system MCBs after CONFIG.SYS processing.
(11/15/94) IBMDOS.COM (Common to all languages)
This version of IBMDOS.COM contains all previous patches.
(02/05/95) IBMDOS.COM
Load path during EXEC is now parsed to not contain and . and ..
entries; also UNC filenames are now handled correctly here.
Volume label can now be deleted through server function call.
Observed problem Lotus 123 v?.?? not loading.
FCB accesses were not working on SUBSTed or ASSIGNed drives. Users
would get critical errors 'FCB unavailable' when attempting to
access an FCB opened on such a drive. (02/06/95)
On directory searches the volume label bit takes now precedence over
all other bits. Not doing so caused the new CBT install to fail. (02/20/95)
Lantastic 5.0 now works correctly. (03/16/95)
(05/08/95) IBMDOS.COM
Fixed memory allocation problem seen with Borland DPMI apps were
memory was allocated from UMB while UMBs were linked in MCB chain
but memory was allocated from conventional memory only.
FindFirst/FindNext now correctly handles VOLUME attribute set along
with other attributes in search flags.
Free memory blocks in upper memory could be left unconcatenated in
certain situations.
File specifications with embedded redundant backslashes were rejected
on MSCDEX (NWCDEX) but allowed (simply removed) by MS-DOS in the
same situation. This resulted in files not being found by certain
utilities.
SOLUTION
XCOPY the new IBMBIO.COM and IBMDOS.COM to the root directory using the /HR
switch. Then, use ATTRIB -A +R +S +H to give the file the System, Read-only
and Hidden attributes.
Example #1 -- from the command line, issue the following separate commands:
XCOPY A:\IBMBIO.COM C:\IBMBIO.COM /HRV
ATTRIB -A +R +S +H C:\IBMBIO.COM
XCOPY A:\IBMDOS.COM C:\IBMDOS.COM /HRV
ATTRIB -A +R +S +H C:\IBMDOS.COM
SYMPTOM
Loss of characters and speed of transmission issues during serial
communications.
SOLUTION
Use SETFIFO.EXE. This utility allows the user to set FIFO buffers of 1, 4,
8, or 14 bytes. This may solve both speed and loss of characters issues during
serial communications--possible only on a 16550 UART chip.
SYMPTOM
(09/29/94) SHARE.EXE (1.01)
Share will now allow file access if file is read only,existing mode and
requested mode are compatability mode and read only mode. int 21 ax=3d00 is
the DOS call affected.
Added setting of the sharing kernal flag during installation
Added check for zero sharing record offset in SFT entry.
(02/01/95) SHARE.EXE (2.03)
SHARE now allocates lock and file space dynamically which allows
for either /F:60000 or /L:4900. One lock can be traded now for 12
bytes of file space.
MS Access 2.0 required for a large database merge more than the
1024 locks that SHARE was limited to before.
(05/08/95) SHARE.EXE (2.04)
SHARE was crashing on load when NCACHE2 was loaded before and both
were using HMA.
SOLUTION
Overwrite the SHARE.COM file in the NWDOS directory with the new SHARE.COM.
SYMPTOM
(11/18/94) KEYB.COM (2.09)
Code added to:
a) process Ctrl Tab
b) support the Brazilian keyboard.
(02/22/95) KEYB.COM (2.10)
Shift Tab and Ctrl Tab are now both working.
If for national keyboards the AltGr variant of a key is undefined
this is now treated as normal Alt (rather than ignored) to be MS-DOS
compatible. (03/14/95)
(05/08/95) KEYB.COM (2.11)
KEYB was crashing on load when NCACHE2 was loaded before and both
were using HMA.
SOLUTION
Overwrite the KEYB.COM file in the NWDOS directory with the new KEYB.COM.
SYMPTOM
(02/28/95) LOCK.EXE
Pressing Ctrl-Break before or when entering the password does no
longer crash the system if BREAK was set to ON.
SOLUTION
Overwrite the LOCK.EXE file in the NWDOS directory with the new LOCK.EXE.
SYMPTOM
(05/08/95) MEM.EXE (1.09)
Total upper memory is now computed correctly.
MEM was crashing if NCACHE2 was loaded due to corruption of the HMA
free block chain, it is now checking for this.
SOLUTION
Overwrite the MEM.EXE file in the NWDOS directory with the new MEM.EXE.
SYMPTOM
(05/10/94) MEMMAX.COM
Some secondary command processors (such as a DOS shell) can no longer change
the memory state.
(03/21/95) MEMMAX.COM
MEMMAX now can enable/disable upper and video memory without being
run from the master command processor. Specifically this allows
these commands to be used from 3rd party shells like 4DOS.
SOLUTION
Overwrite the MEMMAX.COM file in the NWDOS directory with the new MEMMAX.COM.
SYMPTOM
(03/14/95) NWCACHE.xxx - 14 Mar 1995
With VERIFY = ON statistics were in the range of several giga
requests.
SOLUTION
Overwrite the NWCACHE.xxx files in the NWDOS directory with the new NWCACHE.xxx files.
SYMPTOM
(08/16/94) NWCDEX.EXE
This version includes the following fixes. Implementation of a new (missing)
function INT 2Fh, function 150Fh (Get_Directory_Entry). This was done for an
application called REEL MAGIC. For this application there was also a change
made to INT 2Fh, function 1505h (Read_VTOC) to return a large initialised
buffer. There was a change made to Find_Next which fixed the problem related
to the installation of NetWare 4.1 from the CD. There was also a change made
which stopped the '.' and '..' being displayed in the root. One application
fixed by this was REEL MAGIC.
SYMPTOM
(11/16/94) NWCDEX.EXE
fixes several problems. Speeds up CD ROM access considerably.
On detecting that a disk has changed during a chdir/openfile/get file
attribs/dir entry/findfirst, changes to the root.
On calling Int 21/60, the fully expanded path was previously 'Cdex.
X:\filename'. This has now been changed to \\X.\A.\filename which is what
MSCDEX returns. This former discrepancy was highlighted in BYTE.
Fixes a problem seen when CDs are changed and DPMS is loaded.
Updates a) device info word (drive number is 0 based) and b) device driver
pointer (points to CD's current directoy structure) entries in the SFT so that
they are MSCDEX compatible.
Will not automatically return an error during a chdir/openfile/get file
attribs/dir entry/findfirst operation, if the CD has been changed and the
current directory is the root. If the current directory is a subdir and the
volume has changed, an error is returned.
Fixes a problem seen with the game Critical Path.
Fixes a problem to allow the game MYST to install. This must also be used in
conjunction with the new IBMDOS.COM dated 11/15/94.
Fixes a problem reported with INT 2F / Func. 110C.
(12/13/94) NWCDEX (2.5)
a) fixes a problem seen when a CD file's extension is greater
than 3 characters (maximum of 30 characters possible).
In this case, a findfirst/next would not ignore the additional
characters, and would therefore conclude that the extension
did not match the search extension. Effectively, this meant that
some file's were invisible when a DIR was executed.
This problem was seen on a COREL CD.
b) MSCDEX's INT 2F/1510
(Send device driver request) initialises the subunit field
of the device request header based on the drive number
supplied in CX, whereas NWCDEX does not. NWCDEX.EXE
is now compatible with MSCDEX in this respect.
c) fixes a problem seen when accessing subdirectories on
machines with multiple CD-ROMs (>5).
NWCDEX (2.6)
a) Fixes problem seen with LACERTE Tax Software
b) Modifications made to ensure subfunctions 1105,1116,111B,
110F, and 150F will fail on finding a \\ in the pathname.
(01/23/95) NWCDEX (2.7)
Fixes a problem where handles to the CD-ROM device drivers
remain unneccessarily open after NWCDEX initialization is completed.
SOLUTION
Overwrite the NWCDEX.COM file in the NWDOS directory with the new NWCDEX.COM.
SYMPTOM
(08/15/94) PRINT.COM
A new version of PRINT.COM for all languages. This version fixes a problem of
hanging after the PRT-SCR key has been pressed due to incorrect resoration of
INT 05, INT 00, INT 04, INT 06. It has also been modified to leave TAB
expansion to the printer and the Get_Installed_State is now returned in AL and
not AX.
SOLUTION
Overwrite the PRINT.COM file in the NWDOS directory with the new PRINT.COM.
SYMPTOM
Loss of characters and speed of transmission issues during serial
communications.
SOLUTION
Use SETFIFO.EXE. This utility allows the user to set FIFO buffers of 1, 4, 8,
or 14 bytes. This may solve both speed and loss of characters issues during
serial communications--possible only on a 16550 UART chip.
SYMPTOM
(02/22/95) SUBST.EXE (1.03)
Both utilities no longer display invalid (beyond LASTDRIVE) drives
as assigned/substituted.
SOLUTION
Overwrite the SUBST.EXE in the NWDOS directory with the new SUBST.EXE file.
SYMPTOM
(08/26/94) TASKMGR.EXE (2.01)
This version fixes the problem where if the server were loaded
with taskmanager the SFT file count would not be updated on
termination of taskmgr causing possible file corruption.
(11/17/94) TASKMGR.EXE (2.02)
Fixes a problem with BREQUEST. It will also make Taskmgr more
stable with the network loaded.
Fixed problem with PeachTree V8 hanging. (03/28/95)
Now keeps screen parameters for 80x25, 80x28, 80x43, and 80x50
modes upon load and restores them on exit. (04/24/95)
SOLUTION
Overwrite the TASKMGR.EXE file in the NWDOS directory with the new
TASKMGR.EXE.
SYMPTOM
(10/03/94) TREE.COM (1.61)
Fixes system crash when trying to display paths greater than 66 characters.
SOLUTION
Overwrite the TREE.COM file in the NWDOS directory with the new TREE.COM
SYMPTOM
(10/10/94) XDEL.EXE (1.46)
Fixes 3 problems:
1. System crash when trying to recursively delete paths greater than 66
characters.
2. Current directory removed when recursively deleting from the parent dir
(eg. "xdel .. /sd").
3. Top-level directory not removed when password protected.
SOLUTION
Overwrite the XDEL.EXE file in the NWDOS directory with the new XDEL.EXE
SYMPTOM
(10/03/94) XDIR.EXE (2.06)
Fixes divide-by-zero error when trying to recursively display paths greater
than 66 characters.
SOLUTION
Overwrite the XDIR.EXE file in the NWDOS directory with the new XDIR.EXE
