    Five years ago my hard drive crashed and I was unable to get Skymap to work properly.  I reviewed previous posts and believe that the file is working OK.
    The screen view looks normal but when I select F10 to plot the star map there is a slight pause and the screen reverts back to the normal Windows XP screen.  The
    program just ends.
    I assumed that perhaps the default directory was incorrect but it appears to be correct.  I do not know if there is a critical file located outside my default directory that was not installed properly.
    When I use instead of ansi.sys in the config.nt file, I get an error message about loading a 16 bit application and it still does not work.
    I start Skymap by clicking on the MS-DOS batch file icon which is as follows:
    My autoexec.nt file is as follows (windows\system32 directory):
    @echo off
    REM AUTOEXEC.BAT is not used to initialize the MS-DOS environment.
    REM AUTOEXEC.NT is used to initialize the MS-DOS environment unless a
    REM different startup file is specified in an application's PIF.
    REM Install CD ROM extensions
    lh %SystemRoot%\system32\mscdexnt.exe
    REM Install network redirector (load before dosx.exe)
    lh %SystemRoot%\system32\redir
    REM Install DPMI support
    lh %SystemRoot%\system32\dosx
    REM The following line enables Sound Blaster 2.0 support on NTVDM.
    REM The command for setting the BLASTER environment is as follows:
    REM    SET BLASTER=A220 I5 D1 P330
    REM    where:
    REM        A    specifies the sound blaster's base I/O port
    REM        I    specifies the interrupt request line
    REM        D    specifies the 8-bit DMA channel
    REM        P    specifies the MPU-401 base I/O port
    REM        T    specifies the type of sound blaster card
    REM                 1 - Sound Blaster 1.5
    REM                 2 - Sound Blaster Pro I
    REM                 3 - Sound Blaster 2.0
    REM                 4 - Sound Blaster Pro II
    REM                 6 - SOund Blaster 16/AWE 32/32/64
    REM    The default value is A220 I5 D1 T3 and P330.  If any of the switches is
    REM    left unspecified, the default value will be used. (NOTE, since all the
    REM    ports are virtualized, the information provided here does not have to
    REM    match the real hardware setting.)  NTVDM supports Sound Blaster 2.0 only.
    REM    The T switch must be set to 3, if specified.
    SET BLASTER=A220 I5 D1 P330 T3
    REM To disable the sound blaster 2.0 support on NTVDM, specify an invalid
    REM SB base I/O port address.  For example:
    REM DEVICEHIGH C:\Windows\system32\
    My config.nt file is as follows:
    REM Windows MS-DOS Startup File
    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 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 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 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 You can use EMM command line to configure EMM(Expanded Memory Manager).
    REM The syntax is:
    REM EMM = [A=AltRegSets] [B=BaseSegment] [RAM]
    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     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.
    REM dos=high, umb
    REM device=%SystemRoot%\system32\himem.sys
    REM device=%SystemRoot%\system32\ansi.sys
    REM devicehigh=C:\Windows\system32\ansi.sys
    REM files=40
    dos=high, umb
