NOVELL TECHNICAL INFORMATION DOCUMENT TITLE: Novell DOS 7 Update Files DOCUMENT ID: TID500104 DOCUMENT REVISION: B DATE: 22AUG94 ALERT STATUS: Yellow INFORMATION TYPE: Symptom Solution README FOR: D70U06.EXE NOVELL PRODUCT and VERSION: Novell DOS 7 ABSTRACT: This document contains information regarding the following Novell DOS 7 update files: CHKDSK.EXE, DPMS.EXE, EMM386.EXE, HIMEM.SYS, IBMBIO.COM, IBMDOS.COM, MEMMAX.COM, NWCDEX.EXE, PRINT.COM, SETFIFO.EXE, and SHARE.EXE. Items marked with an asterisk (*) indicates FILES, SYMPTOMS and/or SOLUTIONS which are new to this update. Previously updated files contain all prior fixes. ----------------------------------------------------------------- DISCLAIMER THE ORIGIN OF THIS INFORMATION MAY BE INTERNAL OR EXTERNAL TO NOVELL. NOVELL MAKES EVERY EFFORT WITHIN ITS MEANS TO VERIFY THIS INFORMATION. HOWEVER, THE INFORMATION PROVIDED IN THIS DOCUMENT IS FOR YOUR INFORMATION ONLY. NOVELL MAKES NO EXPLICIT OR IMPLIED CLAIMS TO THE VALIDITY OF THIS INFORMATION. ----------------------------------------------------------------- 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.
