SYMPTOM

SAMPLES OF POSSIBLE DR DOS CONFIGURATION FILES

ISSUE/PROBLEM

DR DOS has greatly enhanced CONFIG and BATCH commands. This document
provides examples of how these various commands can be used.

SOLUTION

Only the basic ideas are outlined in each example. The rest of the file
can be filled in with your own ideas.

EXAMPLE 1 - The use of GOTO in the CONFIG file.

?"Do you want to run QEMM (y/n)? " goto QEMM
?"Do you want to run MemoryMAX (y/n)? " goto DRDOS

:QEMM
DEVICE=c:\QTR_DECK\QEMM386.SYS
DEVICE=C:\DRDOS\HIDOS.SYS /B=FFFF
(additional QEMM driver lines go here...)
goto COMMON

:DRDOS
hidos=on
DEVICE=C:\DRDOS\EMM386.SYS /F=AUTO...
...

:COMMON
files=40
hibuffers=20
...

The GOTO statement is used to proceed directly to a label. This function
works like the GOTO statement found in batch file processing.

EXAMPLE 2 - The use of CHAIN in the CONFIG file.

This example shows that you can link to other files that hold your
configurations for each system setup. In the following CONFIG.SYS file,
the two lines direct the configuration process to the files: QCONFIG and
MCONFIG.SYS. The appropriate FILES, BUFFERS, etc. information is contained
within those files and not within the main CONFIG.SYS file. If the
response to both questions is no, a default configuration begins. The
RETURN command cannot be used to return to the parent CONFIG file.

?"Do you want to run QEMM (y/n)? " chain=QCONFIG.SYS
?"Do you want to run MemoryMAX (y/n)? " chain=MCONFIG.SYS
files=40
hibuffers=20
...


EXAMPLE 3 - Using SWITCH/RETURN and labels.

Processing pauses on the SWITCH command until an option is chosen. The
appropriate option is selected by choosing a number. The SWITCH command
then goes to the corresponding label. In the example below 1 selects the
label :NOLIM, 2 selects the label :512K and so forth. The RETURN command
will return processing to the line after SWITCH. Notice the use of the
ECHO statement for setting up the menu options.

ECHO =        Choose how much Extended Memory you want to convert
ECHO =            to LIM Memory for this session.
ECHO =
ECHO =          1 (or ENTER)    No LIM Memory
ECHO =          2               512K of Memory
ECHO =          3               1024K of Memory
ECHO =          4               2048K of Memory
ECHO =
ECHO =         Make your selection...

SWITCH NOLIM, 512K, 1024K, 2048K
GOTO DEFAULTS

:NOLIM
DEVICE=C:\DRDOS\EMM386.SYS /F=NONE /K=AUTO /B=FFFF /R=AUTO RETURN

:512K
DEVICE=C:\DRDOS\EMM386.SYS /F=AUTO /K=512 /B=FFFF /R=AUTO
RETURN

:1024K
DEVICE=C:\DRDOS\EMM386.SYS /F=AUTO /K=1024 /B=FFFF /R=AUTO RETURN

:2048K
DEVICE=C:\DRDOS\EMM386.SYS /F=AUTO /K=2048 /B=FFFF /R=AUTO RETURN
:DEFAULTS
SHELL=C:\COMMAND.COM \C: /P /E:512
HIDOS=ON
HIBUFFERS=20
FILES=30
etc...


EXAMPLE 4 - How to use environment variables in the CONFIG

The use of variables in the CONFIG is not quite the same as in batch
files. Because the command processor (COMMAND.COM) is not loaded until
after CONFIG processing, environment variables are only stored. These
variables are then passed to the command processor where they can be
tested and processed through the AUTOEXEC.BAT or other batch files. It is
not possible to test an environment variable in the CONFIG. The CLS, CPOS,
EXIT and SET commands are featured in this example.

:DEFAULTS
SHELL=C:\COMMAND.COM \C: /P /E:512
HIDOS=ON
HIBUFFERS=20
FILES=30
etc....

ECHO =         Choose which TSRs and Utilities you want loaded
ECHO =               at BOOT time for this session.
ECHO =
ECHO =         1 (or ENTER)   None... just continue
ECHO =         2              Mouse & Cursor Drivers
ECHO =         3              Keyboard "Speeder"
ECHO =         4              Novell Network
ECHO =         5              Done with selections
ECHO =
ECHO =         Make your selection...

:MORE
CPOS 10,33
SWITCH NOTHING, CURSMOUS, SPEEDKEY, NOVELL, DONE
GOTO MORE

:DONE
:NOTHING
CLS
EXIT

:CURSMOUS
SET THINGS=ON
RETURN

:SPEEDKEY
SET SPEEDKEY=ON
RETURN

:NOVELL
SET NETWORK=ON
RETURN

The AUTOEXEC.BAT shown below picks up the environment variables.

The AUTOEXEC.BAT file now allows testing of the environment variables and
executes commands based upon the conditionals illustrated below:

@ECHO OFF
:drdosbeg
VERIFY OFF
PATH C:\;C:\DRDOS;C:\BATS;C:\TOOLS;C:\WINDOWS
if "%things%"=="on" prompt $e[s$e[0;70H$e[1;36m$t$e[u$e[1;36mDR
     DOS6$p$g$e[2;32m
if not "%things%"=="on" PROMPT [DR DOS] $P$G
SET TEMP=C:\TEMP
IF NOT "%TEMP%"=="" MD %TEMP% >NUL
if "%things%"=="on" HILOAD MOUSE
if "%things%"=="on" HILOAD CURSOR /s10
if "%speedkey%"=="on" c:\drdos\mode con:rate=30 delay=1
if "%network%"=="on" hiload c:\lan\ipx
if "%network%"=="on" hiload c:\lan\net3
:drdosend


OTHER EXAMPLES
1) Selecting different configuration options from the CONFIG.SYS file
using the ? key.

?SHELL=C:\COMMAND.COM C:\ /P /E:512
?SHELL=C:\COMMAND.COM C:\ /P /E:1024
?BREAK=OFF
?BREAK=ON
BUFFERS=20
FILES=20
?HISTORY=ON, 256, ON, OFF, OFF
?DEVICE=C:\DRDOS\ANSI.SYS

2) Selecting different AUTOEXEC.BAT's from CONFIG.SYS using the ? and the
Shell statement.

In the Shell statement the /P switch can be followed by a filename. When
present, the named file will be executed instead of the AUTOEXEC.BAT. The
named file must have a .BAT extension and cannot exceed 11 characters
including path.

?"Default Autoexec? (y/n) "SHELL=C:\COMMAND.COM C:\ /P /E:256
?"Alternate Autoexec? (y/n) "SHELL=C:\COMMAND.COM C:\
        /P:ALTERNAT.BAT /E:256

3) Selecting and using different configuration files from CONFIG.SYS at
bootup.

?"Do you want to run Windows? (y/n) " chain = WCONFIG.SYS
?"Do you want to use QEMM? (y/n) " chain = QCONFIG.SYS
?"Do you want to use MemoryMAX? (y/n) " chain = MCONFIG.SYS
?"Do you want to use 386MAX? (y/n) " chain = 386CONF.SYS

Each line is printed on the screen and you are asked to load/run the
chained configuration file. Each configuration file is a complete
CONFIG.SYS type file with all of the appropriate options.

4) The above configuration using "menu" choices with SWITCH.

Note how the "SET environment" variables can be used and tested for
different AUTOEXEC type files in this example.

CONFIG.SYS

ECHO =    1  For Windows Configuration
ECHO =    2  For QEMM Configuration
ECHO =    3  For DR DOS MemoryMAX Configuration
ECHO =    4  For 386MAX Configuration
ECHO =    5  For no Configuration... just exit
SWITCH win, qemm, memm, 386m, none
:none

set autoexec=norm
exit

:win
set autoexec=win
chain=wconfig.sys

:qemm
set autoexec=qemm
chain=qconfig.sys

:memm
set autoexec=memm
chain=mconfig.sys

:386m
set autoexec=386m
chain=386conf.sys

AUTOEXEC.BAT

@echo off
PATH C:\DRDOS;C:\;C:\UTIL;
VERIFY OFF
PROMPT $P$G
DISKMAP C: D:
IF "%autoexec%"=="norm" goto DRDOSEXIT
SHARE /L:40
IF "%autoexec%"=="win" SUPERPCK /EM /L:2048
IF "%autoexec%"=="qemm" CALL QEMM.BAT
IF "%autoexec%"=="memm" SUPERPCK  /A /L:2048
IF "%autoexec%"=="386m" CALL 386.BAT
:DRDOSEXIT

5) Using ANSI

ANSI escape sequences can be used in batch file processing to create
colorful menus. Below is an example of a menu that uses the SWITCH command
and ANSI escape sequences to create a menu.  ANSI.SYS must be loaded in
the CONFIG.SYS to allow for cursor positioning and colors. The first
character after the Echo statement is an ASCII 27 or escape character.
This character may be displayed differently on some printers and monitors
(in fact if you have ANSI loaded you will never see the character when
typed to the screen). To type this character using the DR DOS Editor type
CTRL-P then the ESC key. An alternate method is to type CTRL_Q N and then
type the number 27. Within Editor the ESC character will appear as: ^[ .
If you have downloaded this document from CompuServe or the Novell Host
System the escape sequences have been left intact and you can use the DR
DOS Editor to block out the Echo statements to a file. Then, if ANSI is
loaded when the file is typed to the screen you should see white letters
on a magenta background.

For additional information on ANSI.SYS and escape sequences refer to page
399 of the DR DOS Users Guide.
