Here is what I use:

---------- \batch\boot.bat ----------


@echo off

:start
if "_%1" == "_" goto sayit
if not exist \boot\%1\autoexec.bat goto error
if not exist \boot\%1\config.sys goto error
copy \boot\%1\autoexec.bat \ >nul
copy \boot\%1\config.sys \ >nul
if "_%2" == "_next" goto done
echo last boot was %1 >\boot\lastboot.txt
reboot
echo ERROR - reboot failed
goto done

:sayit
type \boot\lastboot.txt
goto done

:error
echo %0 %1:  ERROR
goto done

:done

------------- debug script reboot.dbg to create \bin\reboot.com -----------

------------ that's all ---------------

First, say "reboot <reboot.dbg".

Then create a subdirectory \boot
Then create \boot\xxx where \xxx is each configuration
Then put appropriate autoexec.bat and config.sys files in each \boot\xxx

Then type "boot xxx" to boot configuration xxx immediately
Or type "reboot xxx next" to boot configuration xxx at the next boot
Or type "boot" to find out what configuration you booted last.
