DOS 6.2 CONFIG.SYS Menu's for Dummies
or How to make multiple configurations run on your computer.
Several people on CompuServe Tandy and IBM forums have asked how to
utilize the DOS 6.2 menu commands in the CONFIG.SYS and AUTOEXEC.BAT
files to create multiple configuration selections for the computer.
Since MicroSoft in their push to conserve paper <G> put most of the
information how to do this in the Help command 'On-Line', and not in the
'hard-copy' manual, it's hard to create your new CONFIG.SYS and AUTO-
EXEC.BAT files and access the 'Help' at the same time.
Of course, you can PRINT out the various help files that refer to the
various menu commands, but an example in front of you, is worth more than
the hassle of going between the manual, DOS Help command and re-entering
your ASCII text editor, to create a working file.
I. Definitions of CONFIG.SYS command items for multiple configurations:
(All taken straight form DOS 6.2 HELP text file.)
DOS 6.2's 'HELP' note <Multi-Config Commands> states:
"A single CONFIG.SYS file can define several different system con-
figurations. To define multiple configurations, you use the following
special CONFIG.SYS commands: "
<Menucolor>
<Menudefault>
<Menuitem>
NOTE: the additional commands <Include> and <Submenu> are not included
in this 'BASIC' example.
Definitions:
A. [menu]: header block tells the booting system that multiple
configurations are included in the CONFIG.SYS file. This is
always the first item at the start of the CONFIG.SYS file.
B. Menucolor: is a command to create color information for the menu screen.
syntax
menucolor=x[,y]
where x= color of text. Valid values from 0 to 15
where y= Optional color of background. Valid values from 0 to 15.
If not included default color is black background
color values:
0 Black 5 Magenta 10 Bright green 15 Bright white
1 Blue 6 Brown 11 Bright cyan
2 Green 7 White 12 Bright red
3 Cyan 8 Gray 13 Bright magenta
4 Red 9 Bright Blue 14 Yellow
NOTE: according to DOS 6.2 values from 8 to 15 on some systems
will cause the screen to blink. Always test before making a final
color statement.
example: menucolor=15,1 (Bright white text on Blue background)
C. Menudefault: is a command that specifies to the system the default
configuration that the computer uses if no selection is
made during startup after a specified time. This command
can only be used within the menu block of the CONFIG.SYS
file. If it is not included the default is set to
menu-item 1.
syntax
menudefault=blockname[,timeout]
blockname is the name of the default selection to be run.
[,timeout] is the optional amount of time the system counts down
from waiting for a key selection. If the timeout is reached
without a valid key selection the default selection is
automatically selected. Valid values are from 0 to 90 seconds
example: menudefault=Home, 15 (Home menuitem is selected after
15 seconds countdown delay.)
D. Menuitem: defines an item in the startup menu. It is used only
within the menu block of the CONFIG.SYS file. Maximum
number of Menuitems is 9. Each Menuitem is a choice that
appears on screen when the system boots up. Each is the
EXACT title of a choice block that follows the menu block
syntax
menuitem=blockname[,menu_text]
blockname is the EXACT title of the associated configuration
block. The configuration block must be defined elsewhere in the
CONFIG.SYS file. If it is selected from the menu, MS-DOS carries
out the commands in the block as well as any commands listed in
the CONFIG.SYS file before the [menu] block and and commands
contained in the [common] header block. NOTE: if MS-DOS cannot
find a block with the specified (EXACT) name the name will not
appear on the startup menu. Maximum length of the block name is
70 characters. Excluded characters are (/), (\), (,), (;), (=)
and ([,]).
,menu_text specifies the EXACT text MS-DOS will display for this
menu item. If not specified MS-DOS will display the menu block
name as the menu item. Maximum of 70 characters with all
printable characters available.
example: menuitem=Home, Home Ram Drive C: External Drive D:
(defines the Home menu block and what is displayed on
the configuration menu screen for this block.
II. Procedure for creating CONFIG.SYS Menu file:
A. Define what configurations you require for your computer.
Examples are:
1. Different users, Single option:
Do different users of the computer require different
configurations? ie: Does Joe require networking and Jane
doesn't. Does Jane need only to start Windows, Does Jack only
require a statistical program to run. Each of these decisions
can create a menuitem option for the menu.
2. Different options, Single user:
Do you require the computer to start different programs or
does the requirements for various programs require diferent
resources (Memory, Drivers, etc) ie:
Portables connected at home to devices or equipment you
don't take on the road.
A Database program that requires different devices that your
word processor program doesn't need.
That BIG game you play requires more memory than your normal
configuration has available.
Again, each of these choices creates a menuitem option.
3. Different users, Multiple options:
Do your different users require different options at
different times? Although I didn't have this problem you can
either create menuitems with different titles for the same
user. ie: Jane-WP, Jane-DB, Joe-1, Joe-2, for example, or use
the Submenu command for nested configurations within a
menuitem. I haven't touched on this command because, I haven't
used it. Other 'experts' can probably provide the expertise to
use this command.
B. Determine the resources required for each menuitem.
On a separate piece of paper for each menu choice, determine
what resources and CONFIG.SYS file commands are needed for each
choice you require.
After you are satisfied that the required items are listed,
place the choices next to each other and compare the items to
find common items that the entire menu can use. Any Common items
can be placed in to a menuitem labeled Common and deleted from the
other menuitem blocks.
Also decide the title of the menu choice that you want to appear
on the Menu screen, It should be descriptive enough so you can
quickly decide which configuration you want to run.
C. Test your configuration blocks.
Once you decide what each configuration should contain, make
sure that each will operate by making temporary CONFIG.SYS and
AUTOEXEC.BAT files to test each choice. This should insure that
they operate without problem, before you combine them in large
files that can be hard to 'Debug'.
NOTE: Don't do this to your CONFIG.SYS and AUTOEXEC.BAT files
that run you computer now, either save you present files so you
can go back to your current configuration, or create a 'Boot
diskette' with all the required resoures and use it to 'cut and
paste' until you are satisfied. Once you have created your final
CONFIG.SYS and AUTOEXEC.BAT files then you can copy them to your
normal boot harddrive or diskette.
HINT: Since it's easy to 'loose' root files when making changes
to your CONFIG.SYS and AUTOEXEC.BAT files, the safest thing that
I've found to prevent this is to create a "Backup" directory
with copies of the curent CONFIG.SYS and AUTOEXEC.BAT files
placed in it, along with any other files that you want to
protect. (COMMAND.COM, Batch files, etc.)
D. Asssembling CONFIG.SYS
Everything checks out? Now comes the 'hard' part putting the
files together so that they work. Place your configuration
blocks in the order you want them to appear on the menu screen
and then start your ASCII word processor or DOS's edit program.
(Look at figs 1.1 and 1.2 for my examples)
Lines 1 thru 9: define the menu screen
line 1: menu block header
line 2 thru 7: define the menu choices and what is printed on
screen. NOTE: The bock item name must be the exact
spelling of the menu block you want to run.
line 8: menucolor tells the system what colors to use on the
screen.
line 9: menudefault what menu choice to use if I don't select a
choice within 30 seconds.
Lines 10, 15, 22,28,33,38: separates the configuration blocks
from each other.
Lines 11,16,23,29,34,39: Are the configuration block headers.
Their spelling must agree with the
choices in the menu header block
above.
Lines 11 thru 14: Common configuration block. What common
resources are common to all possible choices
for systems configurations.
Lines 16 thru 21: Sample config block. What I want the Normal
configuration to use. Note: the LASTDRIVE=K
command is because I use the SUBST command
to identify certain directories as virtual
drives in this configuration.
Happy with your CONFIG.SYS file? OK, save it and then verify
it's ok by testing on your 'scratch diskette', then when you're
finally satisfied save it, and go on to the AUTOEXEC.BAT file.
III. Autoexec.Bat file creation
Now the system will boot up to a selected configuration.
However, you may want to have a certain program start once a
configuration is set. You must write your AUTOEXEC.BAT file to
select the proper commands to run the progam based upon what
configuration you selected. Fortunately, the batch command
GOTO allows this to be done easily. Using the new environment
variable %config%, the AUTOEXEC.BAT looks into the operating
configuration and then selects the correct commands to run.
A. Procedure for creating AUTOEX.BAT file.
1. Decide options you want.
Again, look at what commands you need to run, once each of
the configurations created in the CONFIG.SYS file is selected.
a. Commands common to all choices.
(run these before your menu choices)
b. Windows start up
c. Game choice
d. Comms program (Any Telecommunications software program)
(CompuServe, TE Works, for example)
e. Files copied to Ram Drive
(Some users place frequently used programs on a Ram
Drive to speed up access time.)
f. Commands needed (set prompt for example)
(Set Environment commands are the most obvious)
Each of the above optional choices creates a block in the AUTO-
EXEC.BAT file that must agree in syntax to the environment variable
%menuitem% created in the CONFIG.SYS choice selection.
2. Create menu items on paper.
This sets the sequence you want followed in each choice.
NOTE: The title of the choice 'MUST' match the title of the
configuration block in the CONFIG.SYS file that it is used
with. (see example)
When you copy them to your AUTOEXEC.BAT file, each section
must be separated from the others by a blank line.
3. Test you selections.
Using the same process you used to test your configuration
blocks in the CONFIG.SYS file, test the blocks to insure
they operate correctly before assembling the final AUTO-
EXEC.BAT file.
4. Assemble your AUTOEXEC.BAT file
Once you have verified the blocks work and have placed them
in the order you want. Use your ASCII word processor or DOS's
EDIT to create your AUTOEXEC.BAT file. Remember:
a. That the line "goto %config%" must be included before the
start of the menu choices so the batch file will look into
the environment to see which choice to select.
b. Each title must agree with a configuration block title
ie: :Normal, :Home, :Game, :Comms for example.
Otherwise it will not run.
c. Each choice must be separated by a blank line and must
include the command "goto end" as the last line of each
section. This allows the batch file to automatically end
once all the commands are run by the selected menuitem.
d. The last line in the AUTOEXEC.BAT file must be ":End",
or the batch file will not stop automatically.
Included examples:
Fig 1.1 and 1.2 are CONFIG.SYS and AUTOEXEC.BAT files for a TANDY
1400 dual 3 1/2" floppy drive laptop, with an external 5 1/4" floppy
drive.
Since my Tandy does not allow the CompuServe pgms and an external
drive to co-exist due to memory limitations and the fact that the ex-
ternal floppy is not present when traveling, or when running certain
games, I developed the configurations shown to select the configuration
I need at different times.
Hey, it's an old computer, it works and is paid for, what more do
you want? The basic information will work even on a Pentium class
multi $ special, as long as you have DOS 6.2 loaded.
The only commands that were touched on are the menu items for the
CONFIG.SYS file, and certain commands required in the AUTOEXEC.BAT file,
you should be familiar with all other commands by now.
For clarity each line of the CONFIG.SYS and AUTOEXEC.BAT is numbered
and these numbers should be not be used in actual files. Notes about each
line are separated by "+ +" and should not be included in your files.
1. Menu choices made:
A. On all selections common items required:
load SETVERS, MOUSE and ANSI drivers
B. Home configuration items:
Ram Drive C:
load various DOS files into Ram Drive root directory and certain batch
and small .EXE and .COM files into a subdirectory on the ram drive
external Drive D:
defines the external disk drive as drive D: the configuration
block will load the device driver and identify the drive as the D:
drive
C. GAME1 configuration:
no ram drive
make external floppy drive C:
D. GAME2 configuration:
no ram drive
no external floppy drive
E. COMMS configuration:
no ram drive
no external floppy drive
maximum memory to run large pgme files such as CompuServe
NOTE: This is a slightly different configuration than GAME2.
F. Road configuration:
ram drive as C: drive
load various DOS files into Ram Drive root directory and certain batch
and small .EXE and .COM files into a subdirectory on the ram drive

-----------------------------------------------------------------
NOTE: To those who would like to use multiple configurations, and
haven't upgraded to MS-DOS 6.x, You can operate by creating several
difffernt CONFIG.SYS and AUTOEXEC.BAT files with different titles and
creating a batch file to copy a selected configuration to the CONFIG.SYS
and AUTOEXEC.BAT files that will operate the next time you reboot.
For example using the choices above:
Normal: Ramdrive & External drive= CON1.txt & Auto1.txt
Games1: External drive= CON2.txt & Auto2.txt
Comms: No Ram Drive, External Drive= CON3.txt & Auto3.txt
Your menu choices are:
1. Normal
2. Games1
3. Comms
The choices as selected will copy:
1: CON1.txt to CONFIG.SYS, Auto1.txt to AUTOEXEC.BAT
2: CON2.txt to CONFIG.SYS, Auto2.txt to AUTOEXEC.BAT
3: CON3.txt to CONFIG.SYS, Auto3.txt to AUTOEXEC.BAT
When you 'reboot' the computer starts in the configuration you
selected.
