Command: menudefault
MENUDEFAULT sets a time delayed default option for a config.sys /
fdconfig.sys menu.
MENUDEFAULT is a CONFIG.SYS / FDCONFIG.SYS command.
Syntax:
menudefault=defaultoption,delay
Options:
delay delay time in seconds
defaultoption used standard option if delay time is over
Comments:
MENUDEFAULT sets a time delayed default option for a CONFIG.SYS /
FDCONFIG.SYS menu: If no key has been pressed during 'delay' seconds,
the default choice is activated. Pressing a key stops the countdown,
the kernel will wait infinitely for the user to make a selection. Note
that some virtual machines like Bochs can have broken (too fast) timing.
MENUDEFAULT is a command internal to kernel.sys and needs no other file
in order to work.
Examples:
Example 1:
IN CONFIG.SYS / FDCONFIG.SYS (on a diskette):
menucolor 15,1
MENU Choose wisely:
MENU
MENU 0) normal driver (himemx and jemm386)
MENU 1) alternative driver (jemmex)
MENUDEFAULT=0,5
0?DEVICE=A:\himemx.exe
0?DEVICE=A:\jemm386.exe
1?DEVICE=A:\jemmex.exe
The menu will wait 5 seconds. If no key is pressed in this time,
option 0 is selected automatically. Menucolor 15,1 changes the
colour to white text on blue background.
0 chooses himemx.exe and jemm386.exe,
1 chooses jemmex.exe
Example 2:
IN CONFIG.SYS / FDCONFIG.SYS:
!COUNTRY=049,858,C:\FREEDOS\BIN\country.sys (german setting)
!LASTDRIVE=Z
!BUFFERS=20 (!=will be executed under all circumstances)
!FILES=40 (!=will be executed under all circumstances)
!MENUCOLOR=7,0 (!=will be executed under all circumstances)
MENUDEFAULT=1,5
MENU 1 - Load FreeDOS with JEMM386 (no EMS, max RAM free)
MENU 2 - Load FreeDOS with JEMM386 (Expanded Memory)
MENU 3 - Load FreeDOS low with some drivers (Safe Mode)
MENU 4 - Load FreeDOS without drivers (Emergency Mode)
12?DOS=HIGH (will be processed when pressing 1/2)
12?DOS=UMB (will be processed when pressing 1/2)
12?DOSDATA=UMB (will be processed when pressing 1/2)
123?DEVICE=C:\FREEDOS\BIN\himemx.exe ( " " " 1/2/3)
1?DEVICE=C:\FREEDOS\BIN\jemm386.exe NOEMS X=TEST I=TEST I=B000-B7FF
NOVME NOINVLPG (will be processed when user presses 1)
2?DEVICE=C:\FREEDOS\BIN\jemm386.exe X=TEST I=TEST I=B000-B7FF NOVME
NOINVLPG (will be processed when user presses 2)
34?SHELL=C:\FREEDOS\BIN\command.com C:\FREEDOS\BIN /E:1024
/P=C:\FDAUTO.BAT (will be processed when pressing 3/4)
12?SHELLHIGH=C:\FREEDOS\BIN\command.com C:\FREEDOS\BIN /E:1024
/P=C:\FDAUTO.BAT (will be processed when pressing 1/2)
;1234?BREAK=OFF (set to REM, nothing happens)
REM 1234?DEVICE=C:\blahblah.sys (set to REM, nothing happens)
IN AUTOEXEC.BAT / FDAUTO.BAT:
Depending if you have chosen "1", "2", "3" or "4" in CONFIG.SYS
your AUTOEXEC.BAT / FDAUTO.BAT can execute different routines, e.g.:
IF "%config%"=="1" goto :BAT_ROUTINE1
IF "%config%"=="2" goto :BAT_ROUTINE2
IF "%config%"=="3" goto :BAT_ROUTINE3
IF "%config%"=="4" goto :BAT_ROUTINE4
goto :END
:BAT_ROUTINE1
execute commands for routine1
goto: END
:BAT_ROUTINE2
execute commands for routine2
goto: END
:BAT_ROUTINE3
execute commands for routine3
goto: END
:BAT_ROUTINE4
execute commands for routine4
goto: END
:END
