ID:WA Windows 3.0 and QEMM-386 Advanced Troubleshooting Quarterdeck Technical Note # 207 by David Riess QEMM-386 version 5.11 and above supports Windows 3.0 in all of its processing modes: Real, Standard, and 386 Enhanced. This Quarterdeck Technical Note has been written to help you troubleshoot and fix almost all Windows 3.0 problems which relate to the use of QEMM. We have included an example scenario for you to follow in order to make this process as "user friendly" as possible. This procedure will take at least two steps to complete. You will have to skip ahead to different parts of this technote depending on the results of previous steps, so PLEASE FOLLOW ALL INSTRUCTIONS CAREFULLY. Steps A,B,C,D and E are located at the end of this technote. The Quarterdeck Technical Support Staff handles many Windows 3.0 calls every day, ranging from the simple (e.g., "When I try to load Windows from my local drive, I get the Windows graphics logo but nothing else happens and it takes me back to the C prompt") to the difficult (e.g., "I'm running Windows from the network and I load up my spreadsheet program, then I load up my database program. If I print from the spreadsheet program, then switch to my database program the system crashes. This happens randomly, usually once every 3 days."). This technical note follows the identical procedures which our technical support staff uses to troubleshoot Windows 3.0 with QEMM-386. ------------------------------------------------------------------------ EXAMPLE Windows 3.0 PROBLEM SCENARIO : "I've installed QEMM-386 and have run the OPTIMIZE program to load my TSR's and device drivers into high memory. I'm running Windows from my network drive (drive F:). I get into Windows without a problem, except when I load my scanner program I get an 'UAE: Unrecoverable Application Error' error message and my system crashes". SCENARIO ASSUMPTIONS: QEMM has been loaded onto the local C: drive and QEMM is installed in the C:\QEMM subdirectory. Windows 3.0 has been installed on the NETWORK drive in the F:\WINDOWS subdirectory. INSTRUCTIONS: In each of the following steps you will either edit a file or run a program from the DOS prompt. Whenever you see a number followed by a right parenthesis ), perform the action which follows. Comments regarding the action will be followed in brackets []. Look for the ??? at the end of each step, because a question will need to be answered to determine the next STEP to perform. (STEP 1) DETERMINING YOUR QEMM-386 VERSION --------------------------------- Older QEMM versions can cause Windows 3.0 problems. We have modified QEMM in recent versions to accommodate Windows 3.0 features. This step determines which QEMM version you have, and will direct you to the troubleshooting technique needed for solving your Windows 3.0 problem based on your QEMM version. Enter the following 3 commands at the DOS prompt: 1) C: [go to the QEMM disk-drive ] 2) CD\QEMM [go to the QEMM subdirectory ] 3) QEMMREG [Determine what QEMM version you have] Here's an EXAMPLE of what you should see on your screen: Quarterdeck Expanded Memory Manager 386 V5.13 <----------| Copyright (c) 1986-1991 by Quarterdeck Office Systems | Serial number: 000-B6-0000-000000 | Registered to: Power User | ABC COMPUTER USERS | Anywhere, CA USA | | ??? What version of QEMM is installed on your machine: ---------| 4.00 - 5.10 --------------- any Windows 3.0 processing mode : go to STEP A. 5.11 --------------- Windows 3.0 - Real mode problem : go to STEP 5. Windows 3.0 - Standard mode problem : go to STEP 2. Windows 3.0 - Enhanced mode problem : go to STEP 4. 5.12 or 5.13 --------------- Windows 3.0 - Real mode problem : go to STEP 5. Windows 3.0 - Standard mode problem : go to STEP 5. Windows 3.0 - Enhanced mode problem : go to STEP 4. 6.00 or greater --------------- any Windows 3.0 processing mode : go to STEP 3. *** If QEMMREG returns "Bad command or file name", then either you have a very old version of QEMM-386 (in which you should go to STEP A) or you have erased the file QEMMREG.COM from your QEMM directory (in which case you should re-install QEMM-386 on your hard disk and perform STEP 1 again) *** (STEP 2) DETERMINING YOUR WINDOWS VERSION -------------------------------- You are having problems with Windows 3.0 - Standard mode while using QEMM version 5.11. There are currently 2 versions of Windows 3.0 (version 3.0 and 3.0a). This step determines which Windows 3.0 version you have. To determine if a QEMM upgrade is needed, perform the following 3 commands at the DOS prompt: 1) F: [go to the Windows 3.0 drive ] 1) CD\WINDOWS [go to the Windows 3.0 subdirectory ] 2) DIR WIN*.EXE [get a directory of all .EXE files beginning with WIN] There should be 3 or 4 files listed. Here's an EXAMPLE of what you should see on your screen: F:\WINDOWS>DIR WIN*.EXE Volume in drive F has no label Directory of F:\WINDOWS WINFILE EXE 106288 5-01-90 3:00a WINHELP EXE 193552 5-01-90 3:00a WINVER EXE 8704 5-01-90 3:00a 3 File(s) 6795264 bytes free These files will have the same creation date (in this case 5-01-90). ??? If the Windows 3.0 files creation date is 5-01-90, go to STEP 5. ??? If the Windows 3.0 files creation is later than 5-01-90, go to STEP B. (STEP 3) DETERMINING WHETHER STEALTH IS CAUSING A CONFLICT WITH WINDOWS -------------------------------------------------------------- You have QEMM version 6.00 or greater. Quarterdeck has added the STEALTH feature into your version of QEMM in order to create up to 83K more of HIGH- Ram than versions before 6.00! The STealth feature is invoked with the parameter ST:M or ST:F on the "DEVICE=C:\QEMM\QEMM386.SYS ..." line of your CONFIG.SYS file (located in the root directory of your bootup drive). Your Windows problem may be related to the STealth feature of QEMM, provided you have invoked STealth. We will check your CONFIG.SYS file for the ST:x parameter to determine the next troubleshooting STEP for you to take. With a file editor or file viewer, go to the C:\ directory (root directory of your bootup drive) and load the CONFIG.SYS file. Search the DEVICE=C:\QEMM\QEMM386.SYS line for either ST:M or ST:F. ??? If the QEMM386.SYS line DOES NOT have a ST:M or ST:F parameter (not using the STealth feature) and you are having problems in Windows 3.0 - Real or Standard mode, then go to STEP 5. ??? If the QEMM386.SYS line DOES NOT have a ST:M or ST:F parameter (not using the STealth feature) and you are having problems in Windows 3.0 - Enhanced mode, then go to STEP 4. ??? If the QEMM386.SYS line DOES have a ST:M or ST:F parameter (you are using the STealth feature), then proceed below...: We want to remove all STealth-related parameters (ST:M, ST:F, XST=, XSTI=, DBF=, FSTC, FRAME=) to test whether STealth is involved with your Windows 3.0 problem. Here's an example of removing these parameters: DEVICE=C:\QEMM\QEMM386.SYS R:1 RAM ROM X=D000-D3FF ST:M XSTI=10 <--delete--> DEVICE=C:\QEMM\QEMM386.SYS R:1 RAM ROM X=D000-D3FF Edit your CONFIG.SYS file & remove the STealth-related parameters, then re-boot your computer and try to re-create the problem in Windows 3.0. ??? If the problem still exists and your QEMM version is 6.00 only, please go to STEP C. ??? If the problem still exists and your QEMM version is 6.01 or greater and you are having problems in Windows 3.0 - Enhanced mode, then go to STEP 4. ??? If the problem still exists and your QEMM version is 6.01 or greater and you are having problems in Windows 3.0 - Real or Standard mode, then go to STEP 5. ??? If the problem goes away, then your Windows 3.0 problem is due to a conflict with QEMM's STealth feature. NOW, the next step for YOU is to leave this technical note and get the technote STEALTH.TEC to resolve the STealth conflict. You no longer need this technote! The STEALTH.TEC technical note is available: 1) On Compuserve [GO PCVENB, Library 1]. Download STEALT.ZIP. 2) On Genie [IBM PC Roundtable Software Library 9]. Download STEALTH.TXT. 3) On the Quarterdeck BBS [310-314-3227]. Download STEALTH.TEC. 4) On the Quarterdeck Q/FAX [310-314-3214]. Download FAX# 205 (Q/FAX will automatically fax this back to your fax machine instantly!). 5) Call Quarterdeck Technical Support [310-392-9701] and we will gladly fax/mail it to you. (STEP 4) CONFIGURE WINDOWS TO AVOID CONFLICTS WITH QEMM ---------------------------------------------- You are having problems with Windows 3.0 - Enhanced mode and you have a QEMM version greater than 6.01! Windows 3.0 has several configuration files which it loads at startup. We can modify one of these startup files, SYSTEM.INI, to instruct Windows not to conflict with QEMM. The SYSTEM.INI file is at least 60 lines long and is broken up into sections by brackets [ ]. Add OR modify the following two parameters to the [386Enh] section of the SYSTEM.INI file (located in the WINDOWS directory): EMMEXCLUDE=A000-FFFF \______________________ SystemROMBreakPoint=False / | | The following is an EXAMPLE listing of SYSTEM.INI: | | . | . | . | mouse.drv=Logitech serial mouse | display.drv=VGA | system.drv=MS-DOS or PC-DOS System | [386Enh] <---------------------------------| systemrombreakpoint=false ebios=*ebios display=*vddvga . . . Save the SYSTEM.INI file. Now run Windows 3.0 - Enhanced mode and try to re-create the problem. ??? If the problem still exists, go to STEP 5. ??? If the problem goes away, it has been solved. HAVE A GREAT DAY!!!!! (STEP 5) CREATE A CLEAN ENVIRONMENT FOR QEMM ----------------------------------- To determine whether the Windows 3.0 problem is related to QEMM, you have to remove all unnecessary lines from the CONFIG.SYS and AUTOEXEC.BAT files (pertinent to the problem at hand) and then run Windows to see if the problem still exists. First, you need to make back-up copies of your CONFIG.SYS and AUTOEXEC.BAT files (which are located in the root directory) because we are going to modify these files. To make the back-up copies of these files perform the following 4 commands at the DOS prompt: 1) C: 2) CD\ 3) COPY CONFIG.SYS CONFIG.OLD 4) COPY AUTOEXEC.BAT AUTOEXEC.OLD Now, edit your CONFIG.SYS file so that only the lines that are ABSOLUTELY necessary to re-create the Windows problem remain in the CONFIG.SYS file. You need the QEMM386.SYS line and the FILES= line as a minimum, delete every other line unless it is ABSOLUTELY needed to re- create the problem. The following is an example CONFIG.SYS file for our example: #1 DEVICE=C:\QEMM\QEMM386.SYS RAM AROM=C800-CBFF 2 DEVICE=C:\UTIL\CACHE.SYS #3 FILES=25 4 BUFFERS=30 #5 DEVICE=C:\QEMM\LOADHI.SYS /R:2 C:\SCAN\SCANNER.SYS 256 6 DEVICE=C:\DOS\ANSI.SYS 7 DEVICE=C:\FAXING\FAX.SYS #8 SHELL=C:\COMMAND.COM /P /E:768 #9 DEVICE=C:\QEMM\LOADHI.SYS /R:3 C:\NETW\NETWORK.SYS 10 STACKS=0,0 The # indicates lines which are ABSOLUTELY necessary to include in the CONFIG.SYS file in order to re-create the problem. Let's take a look at why (you may want to look at the Windows 3.0 example problem scenario located on the first page of this Technote, again!): line 1) We NEED the QEMM driver to re-create the problem line 2) A disk cache IS NOT necessary to re-create the problem line 3) we NEED to include the FILES= statement line 4) the BUFFERS statement IS NOT needed line 5) the scanner IS part of our problem line 6) ANSI.SYS IS NOT needed to re-create the problem line 7) the fax board has NOTHING to do with the problem line 8) the SHELL= statement tells DOS where the command processor is line 9) we NEED to log on to the network to run Windows line 10) the Stacks statement IS NOT necessary (if you are not sure if a line is absolutely necessary in YOUR CONFIG.SYS or AUTOEXEC.BAT files, you might try deleting it!) This leaves our CONFIG.SYS with DEVICE=C:\QEMM\QEMM386.SYS RAM AROM=C800-CBFF FILES=25 DEVICE=C:\QEMM\LOADHI.SYS /R:2 C:\SCAN\SCANNER.SYS 256 SHELL=C:\COMMAND.COM /P /E:768 DEVICE=C:\QEMM\LOADHI.SYS /R:3 C:\NETW\NETWORK.SYS Now, since the OPTIMIZE program was executed, some of the device drivers have been loaded high and we have to make sure these drivers are loaded low. This is because some device drivers behave incorrectly when loaded high. All we have to do is remove the LOADHI.SYS (and the /R:x parameter if used) from these lines. DEVICE=C:\QEMM\LOADHI.SYS /R:2 C:\SCAN\SCANNER.SYS 256 <------delete---------> DEVICE=C:\SCAN\SCANNER.SYS 256 This leaves our CONFIG.SYS with DEVICE=C:\QEMM\QEMM386.SYS RAM AROM=C800-CBFF FILES=25 DEVICE=C:\SCAN\SCANNER.SYS 256 SHELL=C:\COMMAND.COM /P /E:768 DEVICE=C:\NETW\NETWORK.SYS Modify the QEMM line to look EXACTLY as follows: DEVICE=C:\QEMM\QEMM386.SYS X=A000-C7FF X=F000-FFFF NO NS NT NCF NOSH DO NOT add the 'RAM' parameter to this line! ??? If you have a version of QEMM greater than 6.00 and are using the STealth parameter (ST:M or ST:F), please DO NOT include this parameter at this time. BUT make a mental note of it, as you will add this parameter back to the QEMM386.SYS line in STEP 10. ALSO, you will want to remove any STealth-related parameters at this time (you may not have any of these) : XST= , XSTI=, DBF=, FSTC, FRAME=. If your QEMM386.SYS line previously contained a parameter to EXCLUDE an area of memory such as EXCLUDE= or X= or AROM= or ARAM=, then you should also add this parameter to the end of the QEMM386.SYS line. DO NOT add any INCLUDE= or I= parameters, if you previously had any! In our example, we previously had the AROM=C800-CBFF parameter. Adding this parameter to the above DEVICE line will look like: DEVICE=C:\QEMM\QEMM386.SYS X=A000-C7FF X=F000-FFFF NO NS NT NCF NOSH AROM=C800-CBFF ^ (Please note that the "AROM=" parameter is NOT on the next line, but is on the same line immediately after "NOSH ". Many editors will allow wrap-around of the same line) and boost the FILES= to at least 40 The final CONFIG.SYS looks like: DEVICE=C:\QEMM\QEMM386.SYS X=A000-C7FF X=F000-FFFF NO NS NT NCF NOSH AROM=C800-CBFF FILES=40 DEVICE=C:\SCAN\SCANNER.SYS 256 SHELL=C:\COMMAND.COM /P /E:768 DEVICE=C:\NETW\NETWORK.SYS (Your CONFIG.SYS may only need the QEMM386.SYS and FILES=40 line. Don't worry if your CONFIG.SYS isn't 5 lines long.) Save the CONFIG.SYS and let's modify your AUTOEXEC.BAT file. The only lines which we need to keep are the PROMPT and PATH statements. The following is an example AUTOEXEC.BAT file for our example: 1 ECHO OFF #2 PATH C:\;C:\DOS;C:\UTILS;C:\EDITOR;F:\WINDOWS; 3 C:\QEMM\LOADHI C:\UTIL\FASTKEYB #4 PROMPT $P$G #5 C:\QEMM\LOADHI /R:1 C:\NETW\LOGIN 6 SET TEMP=F:\WINDOWS\TEMP 7 FAXSETUP 125 The # indicates lines which are absolutely necessary to re-create the problem. Here's why: Line 1) the ECHO statement IS NOT necessary Line 2) We NEED the PATH statement Line 3) Keyboard accelerator IS NOT needed Line 4) Prompt statement is for your convenience Line 5) We NEED to access the network Line 6) This SET statement IS NOT necessary Line 7) The FAX board has NOTHING to do with our problem This leaves our AUTOEXEC.BAT as: PATH C:\;C:\DOS;C:\UTILS;C:\EDITOR;F:\WINDOWS; PROMPT $P$G C:\QEMM\LOADHI /R:1 C:\NETW\LOGIN Now, since we have run the OPTIMIZE program, some of our device drivers have been loaded high and we have to make sure these drivers are loaded low. All we have to do is remove the LOADHI from these lines. C:\QEMM\LOADHI /R:1 C:\NETW\LOGIN <----delete-------> C:\NETW\LOGIN This leaves our final AUTOEXEC.BAT with: PATH C:\;C:\DOS;C:\UTILS;C:\EDITOR;F:\WINDOWS; PROMPT $P$G C:\NETW\LOGIN (Your AUTOEXEC.BAT may only need the PATH and PROMPT lines. Don't worry that your AUTOEXEC.BAT isn't 3 or more lines long) Save the AUTOEXEC.BAT file. Now reboot your machine and try to re-create the problem in Windows. ??? If the problem still exists, go to STEP 6. ??? If the problem goes away, go to STEP 8. (STEP 6) USE THE MICROSOFT DRIVERS INSTEAD OF QEMM-386 --------------------------------------------- Since the problem still exists using a clean environment for QEMM, then we have to determine whether the problem is caused by QEMM or is caused by Windows 3.0. We will now modify your CONFIG.SYS to use the Microsoft drivers instead of QEMM and try to re-create the problem. First, make a back-up copy of the "clean environment" version of CONFIG.SYS file by entering the following 3 commands at the DOS prompt: 1) C: 2) CD\ 3) COPY CONFIG.SYS CONFIG.Q We will attempt to re-create the problem by using the Microsoft drivers, HIMEM.SYS and EMM386.SYS (EMM386.EXE if you are using DOS 5.0), which when loaded together are similar to the Extended and Expanded memory features of QEMM. First, you must find where these files are located on your hard-disk (They are most likely found in the C:\WINDOWS, C:\DOS, C:\ directories). Now, edit the CONFIG.SYS and replace these two drivers for the QEMM386.SYS driver (ASSUME that HIMEM.SYS is in the root directory and EMM386.SYS is in the DOS directory) DEVICE=C:\HIMEM.SYS DEVICE=C:\DOS\EMM386.SYS ON 4096 FILES=40 DEVICE=C:\SCAN\SCANNER.SYS 256 SHELL=C:\COMMAND.COM /P /E:768 DEVICE=C:\NETW\NETWORK.SYS Save CONFIG.SYS, reboot, and try to re-create the problem in Windows. ??? If the problem still exists, then we have determined that QEMM is not responsible for the problems you are having in Windows 3.0. The next STEP would be for you to consult your Windows documentation or contact Microsoft Windows Technical Support at (206) 637-7098 or contact the makers of the resident program or driver which is giving you problems in Windows. ??? If the problem goes away, go to STEP 7. (STEP 7) -------- CONFIGURE QEMM-386 SIMILARLY TO THE MICROSOFT DRIVERS ----------------------------------------------------- We want to find out what Microsoft's drivers are doing to make Windows work properly so that we can configure QEMM to emulate the Microsoft drivers. We must use the MANIFEST program to view what the Microsoft drivers are doing. 1) Exit Windows 3.0 or Reboot your computer to get to the DOS prompt 2) C:\QEMM\MFT.EXE [type this at the DOS prompt to start MANIFEST] The following is an EXAMPLE of the first screen in MANIFEST: Quarterdeck MANIFEST | Overview CONFIG AUTOEXEC Adapters CMOS | | Processor 80386 First Meg | Video Adapter VGA | BIOS Phoenix Expanded | BIOS Date 01/15/88 | Coprocessor None Extended | Keyboard Enhanced | Parallel Ports 2 DOS | Serial Ports 2 | Hints | | Exit | Total Available | Conventional Memory 640K 520K | Expanded Memory 4000K 1520K | Extended Memory 4096K 0K | F1=Help F2=Print | Hit the down-arrow key once (this will give you the First Meg/Overview screen). The box in the center of the screen will look as follows: You will see a screen similar to this: Memory Area Size Description 0000 - 003F 1K Interrupt Area 0040 - 004F 0.3K BIOS Data Area 0050 - 006F 0.5K System Data 0070 - 0FB0 61K DOS 0FB1 - 21F8 73K Program Area 21F9 - 9FFF 504K [Available] Conventional memory ends at 640K A000 - AFFF 64K VGA Graphics B000 - B7FF 32K Unused B800 - BFFF 32K VGA Text C000 - C7FF 32K Video ROM C800 - CFFF 32K Unused D000 - DFFF 64K Page Frame <----------------------------| E000 - EFFF 64K Unused | F000 - FFFF 64K System ROM | | | Look for the Page Frame, we must use the QEMM parameter FRAME= ---| to emulate where the Page Frame is located when using the Microsoft drivers. (Notice that the Page Frame above starts at D000) Hit the ESCAPE key twice to exit MANIFEST and perform the following 4 commands at the DOS prompt: 1) C: 2) CD\ 3) RENAME CONFIG.SYS CONFIG.M [Save the CONFIG.SYS w/Microsoft drivers] 4) COPY CONFIG.Q CONFIG.SYS [Bring back the STEP-5 CONFIG.SYS ] Add the following parameters to the end of the QEMM386.SYS line of your CONFIG.SYS file: X=0000-3FFF NX NR NRH NOVDS FRAME=XXXX ^^^^ (XXXX is the starting memory area of the Page Frame when using the Microsoft drivers on your machine. In this EXAMPLE, FRAME=D000) The QEMM386.SYS line for this EXAMPLE now looks like: DEVICE=C:\QEMM\QEMM386.SYS X=A000-C7FF X=F000-FFFF NO NS NT NCF NOSH AROM=C800-CBFF X=0000-3FFF NX NR NRH NOVDS FRAME=D000 Reboot and try to re-create the problem in Windows. ??? If the problem still exists , then go to STEP D. ??? If the problem goes away, then go to STEP 8. (STEP 8) CREATING HIGH-RAM FOR QEMM -------------------------- We have properly configured QEMM to work with Windows without High RAM. We must add the RAM parameter to end of the QEMM386.SYS line in your CONFIG.SYS to create High RAM. Edit your CONFIG.SYS file and add RAM to the end of the QEMM386.SYS line (DEVICE=C:\QEMM\QEMM386.SYS ... RAM). Reboot your machine and try to re-create the problem in Windows. ??? If the problem re-occurs, then go to STEP 9. ??? If the problem does not occur, then proceed below: In STEP 5, we added the following parameters to the QEMM386.SYS line: X=A000-C7FF X=F000-FFFF NO NS NT NCF NOSH. We will attempt to recover some/all of the HIGH-Ram which we eXcluded. Edit the DEVICE=C:\QEMM\QEMM386.SYS... line of the CONFIG.SYS file and delete (ONE parameter AT A TIME) the following 3 parameters: X=A000-C7FF, X=F000-FFFF, NCF. If removing the X=A000-C7FF parameter does not cause the problem to re-occur, then you don't need this parameter. However if the problem does re-occur, then the parameter needs to be kept. Try this for the other 2 parameters! ??? If the problem still doesn't occur and you WERE using the STealth feature (ST:M or ST:F) from QEMM version 6.00 or greater, then go to STEP 10. ??? If the problem still doesn't occur and you WERE NOT using the STealth feature (ST:M or ST:F) from QEMM version 6.00 or greater, then go to STEP E. (STEP 9) ELIMINATING HIGH-RAM CONFLICTS ------------------------------ It appears that there is a conflict between one of your adapters and QEMM. QEMM is not recognizing that your adapter is there and QEMM is mapping memory on top of the adapter memory. We must exclude all High RAM areas to test this hypothesis and if indeed this is the case, we will systematically narrow down what area really needs to be excluded! 1) C:\QEMM\MFT.EXE [type this at the DOS prompt to start MANIFEST] The following is an EXAMPLE of the first screen in MANIFEST: Quarterdeck MANIFEST | Overview CONFIG AUTOEXEC Adapters CMOS | | Processor 80386 First Meg | Video Adapter VGA | BIOS Phoenix Expanded | BIOS Date 01/15/88 | Coprocessor None Extended | Keyboard Enhanced | Parallel Ports 2 DOS | Serial Ports 2 | Hints | | Exit | Total Available | Conventional Memory 640K 520K | Expanded Memory 4000K 1520K | Extended Memory 4096K 0K | F1=Help F2=Print | Hit the down-arrow key once (this will give you the First Meg/Overview screen). The box in the center of the screen will look as follows: You will see a screen similar to this: Memory Area Size Description 0000 - 003F 1K Interrupt Area 0040 - 004F 0.3K BIOS Data Area 0050 - 006F 0.5K System Data 0070 - 0FB0 61K DOS 0FB1 - 21F8 73K Program Area 21F9 - 9FFF 504K [Available] Conventional memory ends at 640K A000 - AFFF 64K VGA Graphics B000 - B7FF 32K Unused B800 - BFFF 32K VGA Text C000 - C7FF 32K Video ROM C800 - CFFF 32K High RAM <------------| D000 - DFFF 64K Page Frame | E000 - EFFF 64K High RAM <------------| F000 - FFFF 64K System ROM | | | | We want to eXclude all High RAM areas! -------| We do this by using the EXCLUDE= (X= for short) parameter to QEMM. For this example, we have two High RAM areas to exclude: from C800-CFFF and E000-EFFF. The corresponding parameters to ADD to end of the QEMM386.SYS line in the CONFIG.SYS file would be: X=C800-CFFF X=E000-EFFF Add as many X= parameters as needed to your CONFIG.SYS to exclude as many High RAM areas that your machine has. - - - Also consider the following: Do you have a SCSI hard-disk controller and/or a bus-mastering device? If so, perform the following: Locate the DOS driver SMARTDRV.SYS (could be in your C:\DOS , C:\WINDOWS, C:\ directory) and add the following line to your CONFIG.SYS file: DEVICE=C:\WINDOWS\SMARTDRV.SYS 256 256 - - - reboot your machine and try to re-create the problem in Windows. ??? If the problem occurs, then go to STEP D. ??? if the problem goes away, then we know there was a memory conflict and we should now try to narrow down which address range in High RAM has been causing the conflict. This will allow you to get back as much High-RAM as possible! Usually when there is a conflict in memory, there is a 16K area that needs to be excluded and we should now narrow down the eXclusion of High-RAM areas in question. EXAMPLE: We have excluded C800-CFFF which is a 32K area and E000-EFFF which is a 64K area. These numbers are in Hexidecimal (base 16) and may confuse you! (You can access a technical-note on Hexidecimal numbers by calling our Q/FAX line @ 310-314-3214 to download technical-note number 190 to your own fax machine) These 2 areas comprise of 6 different 16K areas (C800-CBFF, CC00-CFFF, E000-E3FF, E400-E7FF, E800-EBFF, EC00- EFFF). To narrow down the area, we would use the X= parameter, trying all six combination, one at a time! More than likely, five out of the six combinations will cause the problem to occur, but one out of the six will resolve the problem. ??? When you have determined which area needed to be excluded, and you WERE using the STealth feature (ST:M or ST:F) from QEMM version 6.00 or greater, then go to STEP 10. ??? When you have determined which area needed to be excluded, and you WERE NOT using the STealth feature (ST:M or ST:F) from QEMM version 6.00 or greater, then go to STEP E. (STEP 10) ADDING THE STEALTH PARAMETER BACK --------------------------------- We have properly configured QEMM to work with Windows 3.0 with High RAM. We must now add the STealth (and any STealth-related) parameter to the end of the QEMM386.SYS line in your CONFIG.SYS to enable STealth. Edit your CONFIG.SYS file and add ST:M or ST:F (and any STealth-related parameter that was ORIGINALLY on your QEMM386.SYS line) to the end of the QEMM386.SYS line: DEVICE=C:\QEMM\QEMM386.SYS ... RAM ST:x [other STealth parameters???]. Reboot your machine and try to re-create the problem in Windows. ??? If the problem still doesn't occur, then go to STEP E. ??? If the problem does re-occur, then your Windows 3.0 problem is due to a conflict with QEMM's STealth feature. NOW, the next step FOR YOU is to leave this technical note (for now) and get the technote STEALTH.TEC to resolve the STealth conflict. The STEALTH.TEC technical-note is available: 1) On Compuserve [GO PCVENB, Library 1]. Download STEALT.ZIP. 2) On Genie [IBM PC Roundtable Software Library 9]. Download STEALTH.TXT. 3) On the Quarterdeck BBS [310-314-3227]. Download STEALTH.TEC. 4) On the Quarterdeck Q/FAX [310-314-3214]. Download FAX# 205 ( Q/FAX will automatically fax this back to your fax machine instantly!). 5) Call Quarterdeck Technical Support [310-392-2701] & we will gladly fax/mail it to you. Once you have resolved the STealth-related problem with the current CONFIG.SYS, then go to STEP E. ------------------------------------------------------------------------ (STEP - A) ---------- You have an older version of QEMM-386 which does not support Windows 3.0 and may contact the Quarterdeck Upgrade Department at (800) 354-3222 or (310) 314-3222 for upgrade requests. Please note that we will upgrade your QEMM-386 to the most recent version ONLY if you have already registered your product! (STEP - B) ---------- Standard mode is not supported for Windows 3.0a with QEMM-386 version 5.11; you may contact the Quarterdeck Upgrade Department at (800) 354-3222 or (310) 314-3222 for upgrade requests. HOWEVER, we do have a patch called WIN300A.PAT which will modify your existing QEMM-386 files to work around the problem (WIN300A.PAT can be accessed on our BBS [310-314-3227], on Compuserve [GO PCVENB , Library 1], on Genie [IBM PC Roundtable Software Library 9] as WIN300A.TXT, or we can fax/mail you this patch when you call technical support). Please note that this patch should only be considered a temporary work-around until your upgrade arrives! (STEP - C) ---------- You have QEMM version 6.00 and there is a known conflict with QEMM and Windows 3.0 when either 1) you are using an application in Windows which uses EMS (expanded memory) or 2) you are loading a device driver or TSR which accesses EMS before entering Windows. Under these circumstances, you will need to upgrade to a QEMM version of 6.01 or greater and may contact the Quarterdeck Upgrade Department at (800) 354-3222 or (310) 314-3222 for upgrade requests. If neither Windows nor any loaded drivers are accessing EMS, then upgrading WILL NOT RESOLVE your Windows problem. If this is the case, please go back to STEP 4 and continue with this technote! PLEASE NOTE: If you are not sure if Windows or any loaded driver is accessing EMS, do not automatically assume that upgrading will resolve your problem. Follow the rest of this technote anyways (because if EMS is not causing the problem, you will waste time upgrading and still have the Windows problem and will still have to continue with this technote!) (STEP - D) ---------- The problem you are having requires further troubleshooting techniques and investigation. Call our Technical Support line at (310) 392-9701 for further assistance. When you call, please have available the following files available: Your original CONFIG.SYS and AUTOEXEC.BAT files CONFIG.SYS (QEMM386.SYS and FILES=) AUTOEXEC.BAT (PATH and PROMPT) CONFIG.Q (only if you have gone thru STEP 6) CONFIG.M (only if you have gone thru STEP 7) (STEP - E) ---------- CONGRATULATIONS, you have successfully configured QEMM-386 and Windows 3.0 to work together! Enter the following 6 commands at the DOS prompt: 1) C: 2) CD\ 3) RENAME AUTOEXEC.BAT AUTOEXEC.Q 4) COPY CONFIG.SYS CONFIG.Q 5) COPY CONFIG.OLD CONFIG.SYS [Bring back your original file] 6) COPY AUTOEXEC.OLD AUTOEXEC.BAT [Bring back your original file] Edit the CONFIG.SYS file and replace the original QEMM386.SYS line with the one you have created by using this technical note (now in CONFIG.Q) and make sure FILES= to at least 40! Reboot the machine and try to re-create the problem in Windows. ??? If the problem is still no longer occurring, the problem is solved. HAVE A GREAT DAY!!! ??? If the problem now occurs, then we know that there is a command line either in your CONFIG.SYS or AUTOEXEC.BAT that has been causing the problem with Windows. To determine which file the command line is in, we will bring back the AUTOEXEC.BAT (Path and Prompt) that we previously created in STEP 5: Enter the following 4 commands at the DOS prompt: 1) C: 2) CD\ 3) COPY AUTOEXEC.BAT AUTOEXEC.OLD 4) COPY AUTOEXEC.Q AUTOEXEC.BAT Reboot your machine and try to re-create the problem in Windows. ??? If the problem still exists, than we know that the command line which is giving us problems is located in the CONFIG.SYS file and if the problem goes away, the command line is in the original AUTOEXEC.BAT file. Now you must systematically determine which command line is giving you trouble! Try deleting one line at a time (if you have a long CONFIG.SYS or AUTOEXEC.BAT file try deleting 2-3 lines at a time) until you find out which line is causing the problem. When you finally determine which line is causing the problem: 1) If the device driver or TSR is loaded into High-RAM, use the procedure in STEP 4 to load it low and see if this corrects the problem. 2) Read the manual or call the technical support of the product which you are loading to determine where the problem might lie. 3) If a TSR or device driver has a parameter that tells it to load/use XMS or EMS, then have it load/use conventional memory instead. 4) Call Quarterdeck Technical Support to determine DOS command problems. 5) JUST GET RID OF THAT LINE! ************************************************************************ *This technical note may be copied and distributed freely as long as it* *is distributed in its entirety and it is not distributed for profit. * * Copyright (C) 1991 by Quarterdeck Office Systems * ************************ E N D O F F I L E *************************
