- HELP WITH CREATING A DOS VMB
- ----------------------------
-
- Creating a DOS 5.0 Image file for OS/2 2.0
- ------------------------------------------
-
- This information is provided as *general guidelines* for creating
- a VIRTUAL MACHINE BOOT ("VMB") from an Image file. Please
- consult OS/2's online help under "Image File" for more information if
- necessary. Your configuration may vary...
- -----------------------------------------------------------------
- You will need to have a DOS 5.0 bootable diskette with the FORMAT
- command in its PATH statement in AUTOEXEC.BAT, or DOS 5.0 installed
- on your hard disk drive also with FORMAT command in its PATH.
-
- 1. Create a bootable 360k or 720k diskette with DOS 5.0. You can
- use high density 1.44mb disk if you wish, but each image file
- you create will equal the size of the diskette you use. By
- using a 360K diskette, your image files will only be 368K in
- size. (You will need to boot with a DOS 5 diskette, and then
- use the FORMAT command with the /S parameter - see your DOS
- manual's FORMAT command information for assistance if
- necessary). You can also create a bootable diskette if you
- have DOS 5.0 installed on your system. Boot up from pure DOS 5.0,
- insert a blank formatted diskette in drive A, and from your DOS root
- directory type "SYS A:".
-
- 2. Boot up in OS/2 and copy all of the following files to the bootable diskette:
-
- From: Filename:
-
- \OS2\MDOS ANSI.SYS
- \OS2\MDOS FSFILTER.SYS
- \OS2\MDOS EMM386.SYS
- \OS2\MDOS HIMEM.SYS
- \OS2\MDOS MOUSE.COM
-
-
- 3. Create with a text editor a CONFIG.SYS file on the Bootable diskette
- like the following: (assumes you have a c:\dos directory - if not "MD DOS"
- from the root directory).
-
- device=himem.sys
- device=emm386.sys
- dos=high,umb
- devicehigh=fsfilter.sys
- devicehigh=ansi.sys
- files=40
- buffers=30
-
-
- 4. Create an AUTOEXEC.BAT file on the bootable diskette *like* the
- following:
-
- echo off
- lh mouse NOTE: (lh = LH)
- path c:\;c:\dos
- prompt $p$g
- c:
- cd \dos
- dos5-img.bat
-
- The last line of the AUTOEXEC.BAT file will load a batch file
- named DOS5-IMG.BAT in the \DOS subdirectory. Use this batch
- file to continue executaion of other programs or utilities.
- See step 5 for a sample batch file.
-
-
- 5. Create a batch file in the \DOS subdirectory named DOS5-IMG.BAT
- similiar to the following:
-
- echo off
- \os2\mdos\fsaccess a:
-
- The second line of this batch file will release access to the
- image file. Otherwise the DOS session thinks the image file
- is drive A, and you will not have access to the physical
- drive A on your system.
-
-
- 6. Open an OS/2 window, and change to your DOS subdirectory,
- type:
- cd \DOS <enter>
- VMDISK A: DOS5.IMG <enter>
-
- This will create an image of the diskette you created in
- steps 1 through 5. The image file will be named DOS5.IMG and
- will be located in the \DOS subdirectory.
-
-
- 7. Exit the OS/2 Window, and return to the Desktop.
-
-
- 8. Create a DOS Window object:
-
- a. Open the " OS/2 System " folder.
-
- b. Double click on the "Command Prompts" icon.
-
- c. Copy the DOS Window icon to the Desktop by holding down
- the CTRL key and dragging the icon to the Desktop.
-
- d. Close the "Command Prompts" and the "OS/2 System" folder.
-
-
- 9. Change the DOS Settings for the DOS Window icon:
-
- a. Select the "DOS Window" icon by clicking on it once.
-
- b. Bring up its menu by clicking the right mouse button once.
-
- c. Click on the ARROW on the "OPEN" line.
-
- d. Select "Settings".
-
- e. In the "DOS Window - Settings" notebook, select "Session".
-
- f. Select "DOS Settings".
-
- g. Change the following settings:
-
- 1. DOS_HIGH to: ON
- 2. DOS_SHELL to: C:\DOS\COMMAND.COM C:\DOS\ /p
- 3. DOS_STARTUP_DRIVE to: C:\DOS\DOS5.IMG
-
- Note:
- If your pc has a LAN adapter, or other board that uses RAM
- memory, add the range it uses to the MEM_EXCLUDE_REGIONS
- settings (ie, C800-CC00 for my Ethernet adapter).
-
-
- There may be other settings you wish to change, but don't
- do it yet. Get the DOS Window up and working first, then
- you can make other necessary changes.
-
-
- 10. Save the settings you changed, and exit the notebook.
-
- 11. Time to test all this stuff out. Double click on your new
- DOS 5 Window, and you there you are!
-
-
- If you have problems with the above steps, please double check
- all your file and directory names, especially the ones in the
- "DOS Settings". If you need more assistance, open the Master Help
- Index and choose Search Topics, and then enter Starting from an
- Image File in the box, scroll down to the DOS section and double
- click on the Starting from an Image File and read the information
- presented there. Good luck!
