- "Shell to DOS from Windows running under OS/2 2.0"
-
- The following is quoted from the OS/2 2.0 README file.
-
- "o Windows programs cannot start DOS sessions or
- DOS programs."
-
- IBM says you can't run Windows apps. in OS/2 2.0 that shell to DOS.
-
- I say you can!
-
- Do you NEED to shell to DOS from Windows under OS/2???
- There is a little Windows zip file utility and some WinBatch stuff
- I like to use, but sometimes they shell to DOS. Now I (and you)
- can use these and many other programs that shell to DOS from
- Windows when in OS/2. NO REBOOTING TO USE THEM!
-
- What do you end up with? Windows 3.0 in Real Mode (Large Frame
- EMS) that can shell to DOS. I end up with 540k+ (550k+ using DRDOS)
- free conventional memory after after starting a DOS session
- from Windows 3.0 under OS/2.
-
- It's a fairly easy 6 part procedure.
-
- 1) Backup your files
- 2) Create a DOS *.IMG file (can use a boot floppy instead)
- 3) Model the IMG config.sys & autoexec.bat files after the
- below examples. Use your particular directory/drive names.
- 4) Adjust settings for the IMG file
- 5) Edit the Windows 3.0 system.ini file
- 6) Run it (WIN /R)
-
- I have not patched any of the OS/2, Windows, or DOS files; I use
- the 3-30-92 OS/2 kernel, but have downloaded a couple of other
- fixes (REXX, com & floppy, VEMM, and Trident video drivers).
-
- What do you need?
-
- You need Microsoft Windows 3.0 and Win3 needs to be started from
- a DOS *.IMG file (MS DOS 5 and DR DOS 6 both work) or Drive A:
- DOS. It also helps to have 4DOS.COM (shareware) replace COMMAND.COM
- as 4DOS can load conventional, XMS, EMS or swap to disk if needed.
- 4DOS gives me almost 10k more of 1st 640k than COMMAND.COM.
-
- I have both MSDOS.IMG and DRDOS.IMG files I use. The only
- difference seems to be that DEVICEHIGH= (HIDEVICE) doesn't
- seem to work on the DRDOS.IMG; the files load low with every
- combination I've tried.
-
- The following refers to a MSDOS.IMG file but can be used for
- DRDOS as well.
-
- Create your IMG file as per OS/2 online instructions.
- To save hard drive space use the smallest floppy available to create
- your IMG file. I dusted off an old single-side 1D floppy (160k) for
- my IMG files. Do they still make 160k floppies?
-
- Sample IMG config.sys:
-
- DEVICE=FSFILTER.SYS
- DEVICE=F:\OS2\MDOS\HIMEM.SYS
- DEVICE=F:\OS2\MDOS\EMM386.SYS
- REM Next line for DRDOS IMG
- REM DEVICE=C:\DOS\HIDOS.SYS /B=FFFF
- DOS=HIGH,UMB
- REM Do not use \os2\mdos\COMMAND.COM supplied with OS/2
- REM SHELL=C:\COMMAND.COM C:\ /P /E:1024
- SHELL=F:\4D\4DOS.COM F:\4D @F:\4D\MSDOSIMG.INI /P
- REM May use fewer files
- FILES=99
- REM Use HIBUFFERS for DRDOS
- BUFFERS=25
- DEVICEHIGH=F:\OS2\MDOS\ANSI.SYS
-
- Sample IMG autoexec.bat:
- (If you mention WINOS2 in your PATH, place your Windows 3.0
- directory before it; your true DOS should be before \os2\mdos)
-
- @ECHO OFF
- SET PCTOOLS=D:\PCT\DATA
- SET TEMP=E:\TEMP
- SET TMP=E:\TEMP
- REM Next line I use for WinBatch
- SET IMGFIL=YES
- REM Next line is for 4DOS
- SET _CDPATH=D:\QHS;D:\;D:\WIN;E:\;F:\;C:\;D:\OV;D:\WS;F:\OS2;D:\;F:\OS2\MDOS;
- PATH F:\4D;C:\DD;D:\WIN;C:\DOS;D:\WP;D:\XL;D:\OV;D:\WS;D:\CC;D:\CC\CAM;D:\PCT;
- REM Next 2 lines activate my numlock and capslock that OS/2 turns off
- NUMLOCK
- CAPSLOCK
- PROMPT $i$E[1;32mTime $T$_Date $D$E[1;31m [MSDOS IMG] $P$G$E[0;1m
- F:\OS2\MDOS\MOUSE
- REM Next 2 lines are for 4DOS
- ALIAS /P /R F:\4D\ALIASMSD.TXT
- HISTORY /R F:\4D\HISTQHS.TXT
- F:
- ECHO Edit IMG files now if needed.
- ECHO Enter FSACCESS A: for "normal" A: drive access.
-
- My "settings" for MSDOS.IMG include DOS full screen DOS_RMSIZE 640,
- KBD_CRTL_BYPASS CTRL_ESC, EMS_FRAME_LOCATION AUTO,
- EMS_MEMORY_LIMIT 2048, XMS_MEMORY_LIMIT 2048,
- DOS_STARTUP_DRIVE F:\OS2\MSDOS.IMG, DOS_UMB ON, DOS_HIGH ON.
-
- Lastly, you need to make a slight change to the Windows 3.0
- system.ini file if you want to use your mouse. In the [BOOT]
- section there is the line: mouse.drv=mouse.drv
-
- REM the line by placing a semicolon ";" in front of it.
-
- ;mouse.drv=mouse.drv
-
- Add the line:
-
- mouse.drv=<your drive>:\os2\mdos\winos2\system\mouse.drv
-
- Use the full path as above. DO NOT overwrite your "normal"
- Windows mouse.drv by copying the file from OS/2 (read on).
-
- Doing the above system.ini editing substitutes the winos2 driver
- for the the Windows 3.0 mouse driver. The above assumes a standard
- Microsoft compatable mouse. Note, if you later decide to boot
- DOS and want to run Windows 3.0, REM out ";" the winos2 driver
- and unREM the regular Windows 3.0 driver. Windows 3.0 may not start
- under DOS if the winos2 driver is used.
- Addendum (revised 08-05-92)
-
- DR DOS USERS: Include both HIDOS=ON and DOS=LOW,UMB in your
- IMG config.sys. You'll add almost 8k to your
- available 1st 640k in the session.
-
- ***Potential problem areas & solutions.***
-
- ALL USERS: The mouse command in the IMG autoexec.bat is
- required for mouse use. This is in addition
- to editing Windows 3.0 system.ini.
-
- In the IMG file autoexec.bat, set your TEMP
- (TMP) environment to some drive and/or
- directory other than where your OS/2 swappath
- is. Check your OS/2 config.sys. You'll find
- a line similar to:
- SWAPPATH=E:\ 2048 2048
- In the above example OS/2 is swapping to the
- root directory on E drive. For this example you'd
- set your IMG file TEMP environment somewhere other
- than the root directory of E.
- SET TEMP=E:\TEMP works in my IMG file autoexec.bat.
-
- If you have 2048k or less free on the SWAPPATH drive
- (referring to above example), set the IMG's TEMP to
- a different drive.
-
- In Windows 3.0 SYSTEM.INI there is a section: [NonWindowsApp]
- You may or may not have any entries in the section. If,
- however, there is an entry that begins
- swapdisk=
- be sure it does not point to the SWAPPATH directory.
- Swapdisk= tells windows where to swap non-windows apps.
- when in standard and REAL modes. The Windows default
- (no entry) is the TEMP environment or the Windows directory
- if there is no TEMP environment. You may need to REM
- the line (use a semicolon ";" as instructed earlier).
- See sysini.txt.
-
- In Windows 3.0 WIN.INI the [windows] section may
- contain the line: swapdisk=
- This is in addition to the SYSTEM.INI entry.
- This entry should indicate the same path as the
- SYSTEM.INI notation. If there is no SYSTEM.INI
- entry or you used the REM ";" suggestion, then the
- WIN.INI should be:
- swapdisk=
- (nothing after "=")
-
- OS/2 config.sys should include DOS=HIGH,UMB;
- RMSIZE=640; along with all the v*.sys statements OS/2 adds.
- Be sure your OS/2 config.sys loads vemm.sys & vxms.sys.
-
- You might also add the line:
- SET COMSPEC=<your command processor>
- to your IMG autoexec.bat. Refer to your MSDOS or
- DRDOS user's guides for more info on SET, SHELL,
- and COMSPEC.
-
- Files & Dates
-
- The procedure works without using any "fixes" that have been released
- (OS/2 2.0 with all files dated 3-30-92). This is sometimes
- called the GA version. Below are some IBM "fixes" that the author
- has downloaded and tried/uses. The procedure also works with the
- following replacing the initial GA version files. Others may be added
- to the list as they are downloaded and tried.

- VCOM.SYS 4-24-92
- VEMM.SYS 4-21-92
- VSVGA.SYS 4-20-92
-
- Windows 3.0 files are all 5-1-90 with the exception of Trident
- video support: 386grabber=tvga.gr3 6-18-90
- display.drv=t640.drv 3-11-91 (256 color VGA)
-
-
- This zip file was created by a Windows program that starts PKZIP.EXE
- version 1.1 (a DOS program) to do the zipping. It was done using
- the procedure as described above.
-
- This zip was uploaded to CompuServe using CIM.EXE
- (CompuServe Information Manager), a DOS program started
- from Windows 3.0 under OS/2 2.0 using this procedure.
-
- If you'd like a 160k IMG file for OS/2 and can't make one
- yourself, mail a bootable floppy (msdos.sys, io.sys, & command.com
- for MS DOS; ibmbio.com, ibmdos.com, & command.com for DR DOS) up to
- 1.44meg to the below address. Also include the file fsfilter.sys.
- There is a $5.50 fee (check or money order) per IMG for this
- service which includes return by US mail of your floppy with the
- 160k IMG file on it. I'll include NUMLOCK.COM & CAPSLOCK.COM.
-
- Mail fees (check or money order), floppies, name, address to:
