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).
|
||
|
||
|
||
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)
|
||
|
||
|
||
|
||
the following advanced config.sys processing options are available:
|
||
|
||
normal
|
||
FILES=20
|
||
DEVICE=MyNetWorkDriver.sys
|
||
|
||
'?' - ALWAYS ask if a single line shall be executed
|
||
|
||
FILES=20
|
||
?DEVICE=MyNetWorkDriver.sys
|
||
|
||
|
||
'!' - NEVER ask if a single line shall be executed, even if single stepping
|
||
|
||
!FILES=20
|
||
!DOS=HIGH,UMB
|
||
!BUFFERS=30
|
||
DEVICE=MyNetWorkDriver.sys
|
||
|
||
|
||
|
||
configuration management - you may compose several configurations,
|
||
using following special commands:
|
||
|
||
MENU
|
||
MENU select your configuration
|
||
MENU
|
||
MENU use (0) for basic configuration
|
||
MENU use (1) for CDROM operation
|
||
MENU use (2) for NETWORK configuration
|
||
MENU
|
||
MENUDEFAULT=0,1 ( configuration 0, wait 1 second)
|
||
|
||
|
||
1? rem CDROM
|
||
1? device=CDROM.SYS
|
||
|
||
2? rem NETWORK
|
||
2? device=MyNetworkDriver.SYS
|
||
|
||
|
||
Although this is definitively worse then MSDOS menuing possibilities,
|
||
IMHO it's better then nothing.
|
||
|
||
It's also possible to combine menu options, to avoid writing thing every
|
||
time again.
|
||
constructions like 0?devicehigh?=cdrom.sys are also possible
|
||
("if menu option 0 chosen, ask if you want to load this driver")
|
||
|
||
the selected configuration can be determined in AUTOEXEC.BAT in the
|
||
environment variable CONFIG like
|
||
|
||
if %CONFIG% == 0 echo configuration 0 selected
|
||
|
||
however, if you have no menu's in config.sys, then %config% has no value,
|
||
thus resulting in "IF == 0 echo configuration 0 selected."
|
||
(which causes syntax errors as there's nothing on the left side of == )
|
||
|
||
That's why you better use something like:
|
||
if [%config%]==[0] echo configuration 0 selected. -or-
|
||
if "%config%"=="0" echo configuration 0 selected.
|
||
|
||
then if there is no menu you have: "IF []==[0] echo configuration 0 selected."
|
||
(which will of course output nothing)
|
||
|
||
thus my config.sys now looks like
|
||
|
||
|
||
!files=20
|
||
!dos=high,umb
|
||
!break=off
|
||
!buffers=30
|
||
!screen=0x12
|
||
!lastdrive=z
|
||
!shellhigh=a:\command.com /p /e:512 /MSG
|
||
|
||
MENU
|
||
MENU 0 - SoftIce+HIMEM+Network (default)
|
||
MENU 1 - SoftIce+HIMEM
|
||
MENU 2 - HIMEM+EMM386
|
||
MENU
|
||
MENUDEFAULT=0,0
|
||
|
||
|
||
01? DEVICE=C:\NUMEGA\S-ICE.EXE /TRA 3000 /SYM 400
|
||
012?DEVICE=himem.exe
|
||
01? DEVICE=UMBPCI.SYS
|
||
2? DEVICE=EMM386.EXE NOEMS
|
||
|
||
0?device=c:\ntclient\ifshlp.sys
|
||
|
||
DEVICE=ATAPICDD.SYS /D:MSCD000
|

||
Full Screen Menus (thanks to Rune Espeseth)
|
||
|
||
Use MENUCOLOR=foreground[,background] to obtain a full screen menu
|
||
where you can use the arrow keys. Example (note that box drawing
|
||
characters are used that look strange in other character sets):
|
||
|
||
REM *** This is the FreeDos Config.sys ***
|
||
REM *** executed before autoexec.bat ***
|
||
|
||
REM *** Set white foreground, red background ***
|
||
menucolor=7,4
|
||
|
||
files=20
|
||
buffers=20
