Advanced - FreeDOS specific - CONFIG.SYS processing
a new command DOSDATA=UMB
DOSDATA=UMB loads some FreeDOS specific stuff in Upper Memory Blocks,
like the RAM that FILESHIGH, LASTDRIVEHIGH, and STACKSHIGH occupy
a new command ECHO
ECHO does ECHO its argument (surprised ?-) and is executed at
the time the DEVICE= lines are executed.
use it similarly to
ECHO loading driver 1
device=Driver1.sys
ECHO driver1 successfully loaded
a new command called EECHO is also available, for echo-ing ANSI Escape Sequences
(redefines keyboard input for example).
Configuring your DOS system for use:
------------------------------------
When booting DOS, you will find it only supports a subset of
the devices available on many computers. To support additional
devices and advanced features, device specific driver and
memory resident software most be loaded. This allows the
kernel to be easily extended to support hardware not presently
available and take better advantage of installed hardware
without wasting resources on computers lacking it. This
software is generally loaded during the kernel initialization
phase, with details describing what to load expressed in the
file CONFIG.SYS. The FreeDOS kernel will first look for a
file named FDCONFIG.SYS, should it exist, it will will be used
instead of CONFIG.SYS; this allows the FreeDOS kernel to coexist
and be configured differently than another DOS kernel. There
are additional options available to adjust other aspects of the
kernel's behaviour. Note: some options listed below are FreeDOS
specific and will not work when using other/older DOS kernels.
Below is list of all documented FreeDOS config.sys supported
options; additional undocumented options may exist but are not
meant for normal usage.
an undocumented command SCREEN=xx
SCREEN= switches into videomode xxx (INT10/11xx/000)
useful
SCREEN=0x11 -- 28 lines
SCREEN=0x12 -- 43/50 lines (on EGA/VGA)
BREAK
Usage: break=on|off
Set extended Control-C/Control-Break checking to on [default] or off.
When set to on, the kernel will perform the check (and invoke current
handler if pressed) prior to most int 21h calls. When set to off,
the kernel only performs the check on I/O calls using standard streams.
e.g. break=off
BUFFERS
BUFFERSHIGH
Usage: buffers=nn[,n] where nn is in range 1-99 & n is in range 1-8
Memory buffers used by the kernel; primary[,secondary]
The secondary buffer option is available for compatibility with
other DOS kernels, but is ignored by the FreeDOS kernel.
e.g. buffers=20
COUNTRY
Usage: country=nnn[,[mmm][,[d:][path]file]]
Only limited country=nnn support is presently available.
Enables/sets international features of DOS
nnn is country code (001==US)
mmm is code page (437 is default, 850 is updated form, 1252 for Windows)
[drive][path]file specifies file with country specific data
e.g. country=001,850,C:\FDOS\BIN\COUNTRY.SYS
DEVICE
Usage: device=[d:][path]file [options]
Load the device driver specified by d:path\file (into conventional
[low 640KB] memory). The options are for the driver itself; refer
to documentation that came with your particular device for supported
options and their usage.
e.g. device=himem.sys
DEVICEHIGH
Usage: devicehigh=[d:][path]file [options]
This is just like device= statement, except it attempts to load
the device driver into high memory first (failing that it should
load it in conventional memory).
Note: The order you load devices may have a large impact on amount
of free memory available. In general try to load large (in memory
usage) programs into high memory first.
Important: You should have a high memory manager such as FDXMS or
Himem installed (prior device=FDXMS.SYS or device=HIMEM.SYS) before
using this option.
e.g. devicehigh=atapicdd.sys /D:FDCD0001
DOS
Usage: dos=high|low,umb|noumb
Indicates whether the kernel should try to load itself into
high memory or only conventional (low), and whether to link
upper memory blocks in with normal memory or not.
Note: only one set need be given, ie dos=high and dos=noumb are ok.
Important: if you specify dos=high[,umb|noumb] then you must also
load a high memory manager (first), ie FDXMS or HIMEM
e.g. dos=high,umb
or dos=low,noumb
DOSDATA
Usage: dosdata=umb
Try to load kernel data into Upper Memory Blocks; effectively
same as using the <name>HIGH variant of kernel parameters,
such as fileshigh, lastdrivehigh, and stackshigh (does not
effect drivers loaded using device= or install=).
e.g. dosdata=umb
ECHO
Usage: ECHO Message to be displayed to user.
ECHO displays (echos) its arguments to the console during
config.sys processing when device drivers are loaded (when
DEVICE= lines are executed).
e.g.
ECHO loading driver 1
device=Driver1.sys
ECHO driver1 successfully loaded
EECHO
Usage: EECHO Message with ANSI Escape Sequence
EECHO allows for echo-ing ANSI Escape Sequences
(redefines keyboard input for example). Use a dollar sign ($)
to represent the ANSI Escape character. Note: requires an
ansi driver loaded prior to use.
FCBS
Usage: fcbs=nnn
where nnn is in range 1-255
Sets the number of File Control Blocks to reserve room for.
As file control blocks have been replaced by file handles
(see files) most applications will not need this value adjusted.
e.g. fcbs=4
FILES
FILESHIGH
Usage: files=nnn
where nnn is in range 8-255 (default 8)
Specifies how many files allowed open at once (reserves
memory necessary to support opening this many files).
Note: there are other restrictions, so a given program
may not be able to actually open this many
A good number is 20, though some programs suggest/require
30, 40, or even 255
e.g. files=20
INSTALL
INSTALLHIGH
Usage: install=[d:][path]file [options]
Load the program specified by d:path\file. Generally used to
load TSR (terminate and stay resident) programs with a minimal
environment block. The options are for the program itself; refer
to documentation that came with your particular software for
supported options and usage.
e.g. install=nansi.com
LASTDRIVE
LASTDRIVEHIGH
Usage: lastdrive=x
where x is last drive letter available for use; A-Z
e.g. lastdrive=z
NUMLOCK
Usage: numlock=on|off
Set the keyboard number lock to on or off.
e.g. numlock=off
REM
Usage: rem Your remarks!
This provides the ability to place comments within the configuration
file. The text following the rem until the end of the line is
reached are ignored. This may also be used to temporarily disable
loading a particular device or other option.
SCREEN
Usage: screen=xx
Switches into videomode xxx (INT10/11xx/000)
where xx should be 0x11 for 28 lines or 0x12 for 43/50 (EGA/VGA) lines
SET
Usage: set ENVVAR=value
Sets the environment variable to provided value.
e.g. set HOME=C:\home\me
SHELL
SHELLHIGH
Usage: shell=[d:][path]file [options]
Indicates the shell to use; often used to alter COMMAND.COM's behavior.
Note: it is command.com that processes AUTOEXEC.BAT; by using the
shell option, you can get command.com to process a differently named
file (such as FDAUTO.BAT for coexisting with another DOS using different
configuration options) or run a completely different command interpreter
such as 4DOS or a (unix) sh variant.
e.g. shell=C:\COMMAND.COM /E:256 /P
STACKS
STACKSHIGH
Usage: stacks=nn,nnn
where nn is in range 0,8-64 and nnn is in range 32-512
Changes number of stacks available
nn is number of different stacks and nnn is size in bytes of each one
e.g. stacks=16,256
SWITCHAR
Usage: switchar=c
Sets the default switchar to character c. Where c is a single character
that is used to indicate a command line parameter is an option switch.
The default is a forward slash (/). Note: This simply sets the value
returned by a get switchar query, it will not effect programs that use
hardcoded switch characters.
e.g. switchar=-
VERSION
Usage: version=x.y
FreeDOS specific command to specify what DOS version to report.
e.g. version=6.2
the following advanced config.sys processing options are available:
Advanced - FreeDOS specific CONFIG.SYS menu processing:
-------------------------------------------------------

FILES=20
DEVICE=MyNetWorkDriver.sys

Although this is definitively worse then MSDOS menuing possibilities,
IMHO it's better then nothing.
Although this is different than MSDOS menuing possibilities, it
allows for selecting from multiple options during bootup while
remaining simple. It, however, does not allow for multi-level
menuing based configuration schemes.
It's also possible to combine menu options, to avoid writing thing every
time again.
