-----------------------------------------------------------------

SYMPTOM

 -CHKDSK is not compatible with Stacker 4.0 drives.

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

 -Speed issues with the NWCDEX CD-ROM extension driver.

SOLUTION

Overwrite the NWCDEX.EXE file in the NWDOS directory with the new NWCDEX.EXE.
This is the German version of NWCDEX that may help with some speed issues that
are encountered.


SYMPTOM

 -Users may experience minor problems with the DPMS.EXE file that ships with
Novell DOS 7.

SOLUTION

 Overwrite the DPMS.EXE file in the NWDOS directory with the new DPMS.EXE.


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.


SYMPTOMS

 -Minor problems may occur with NE2100 cards.

 -Minor problems may occur with a second DMA controller on PS/2 and compatible
machines when channels 5, 6 or 7 are selected.

 *Problems running CodeView when DPMI is enabled.

 *VCPI memory not being released in Task Manager upon exiting BCC32 from
Borland C++ Version 4.

SOLUTION

 Overwrite the EMM386.EXE file in the NWDOS directory with the new EMM386.EXE
file.


SYMPTOM

 -Some EMS page frame problems may occur with HIMEM.SYS.

SOLUTION

 Overwrite the HIMEM.SYS file in the NWDOS directory with the new HIMEM.SYS
file.


SYMPTOM

 -Some secondary command processors (such as a DOS shell) can change the
memory state.

SOLUTION

 Overwrite the MEMMAX.COM file in the NWDOS directory with the new MEMMAX.COM
file. Only the primary command processor can now change the  memory state.


SYMPTOMS

 -Accessing 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.

 -A double \\ appearing with NetWare 4.x LOGIN.EXE.

  For example: "D:\\filename.ext"

 -The system sometimes reads beyond the end-of-chain when corrup directory
entries are encountered.

 -The key combinations of ALT-T and ALT-Q not working correctly with the
Colorado Tape software.

 -Problem with initializing IRMA 3270 emulation software by DCA.

 *Inability to start a DOS session under OS/2 due to SETVER returning an
invalid version number.

 *SETVER returning an invalid version number during a VM boot in which a 3rd
party device driver takes over INT 21.

*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

 *Files that are open on a PNW server can be renamed by a client station.
      
*SOLUTION

 COPY the new SHARE.EXE to your Novell DOS 7 subdirectory and then 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 as shown in Example #1 above.

 !NOTE:
  IBMBIO.COM, IBMDOS.COM and SHARE.EXE are rebuilds containing all previous
fixes (where applicable.)

  !!!THESE THREE FILES MUST BE USED TOGETHER - DO NOT MIX VERSIONS!!!


*SYMPTOM

 *Machine hangs after the PRT-SCR key has been pressed when PRINT.COM is
loaded.

 *Tabs not being expanded properly with PRINT.COM.

*SOLUTION

 Overwrite PRINT.COM with the new PRINT.COM file.

Installation Instructions:

Make a backup copy of each file being replaced before copying the new file
into that same directory.  The integrity of any file can be verified by
comparing the file's checksum with the above information.  To calculate the
checksum of any file, use the Novell DOS 7 command XDIR <filename.ext> /C 
from the command line.
