CONFIG.NT

REM Windows MS-DOS Startup File

REM

REM CONFIG.SYS vs CONFIG.NT

REM CONFIG.SYS is not used to initialize the MS-DOS environment.

REM CONFIG.NT is used to initialize the MS-DOS environment unless a

REM different startup file is specified in an application's PIF.

REM

REM ECHOCONFIG

REM By default, no information is displayed when the MS-DOS environment

REM is initialized. To display CONFIG.NT/AUTOEXEC.NT information, add

REM the command echoconfig to CONFIG.NT or other startup file.

REM

REM NTCMDPROMPT

REM When you return to the command prompt from a TSR or while running an

REM MS-DOS-based application, Windows runs COMMAND.COM. This allows the

REM TSR to remain active. To run CMD.EXE, the Windows command prompt,

REM rather than COMMAND.COM, add the command ntcmdprompt to CONFIG.NT or

REM other startup file.

REM

REM DOSONLY

REM By default, you can start any type of application when running

REM COMMAND.COM. If you start an application other than an MS-DOS-based

REM application, any running TSR may be disrupted. To ensure that only

REM MS-DOS-based applications can be started, add the command dosonly to

REM CONFIG.NT or other startup file.

REM

REM EMM

REM You can use EMM command line to configure EMM(Expanded Memory Manager).

REM The syntax is:

REM

REM EMM = [A=AltRegSets] [B=BaseSegment] [RAM]

REM

REM     AltRegSets

REM         specifies the total Alternative Mapping Register Sets you

REM         want the system to support. 1 <= AltRegSets <= 255. The

REM         default value is 8.

REM     BaseSegment

REM         specifies the starting segment address in the Dos conventional

REM         memory you want the system to allocate for EMM page frames.

REM         The value must be given in Hexdecimal.

REM         0x1000 <= BaseSegment <= 0x4000. The value is rounded down to

REM         16KB boundary. The default value is 0x4000

REM     RAM

REM         specifies that the system should only allocate 64Kb address

REM         space from the Upper Memory Block(UMB) area for EMM page frames

REM         and leave the rests(if available) to be used by DOS to support

REM         loadhigh and devicehigh commands. The system, by default, would

REM         allocate all possible and available UMB for page frames.

REM

REM     The EMM size is determined by pif file(either the one associated

REM     with your application or _default.pif). If the size from PIF file

REM     is zero, EMM will be disabled and the EMM line will be ignored.
