Excluding Support for MS-DOS and Windows 16-bit Applications

To exclude the files needed to support for MS-DOS and Windows 16-bit applications, you must modify the INITIAL.INF file, commenting out the routine that modifies the Registry key for MS-DOS and Windows 16-bit support.If the supporting files are excluded but this routine is not commented out, Setup will report an error. Lines should be commented out using the semicolon (;) as shown in the following example:

;vdmconfig =+ ; shell "subroutn.inf" PushBillboard STATUSDLG $(Billboard5) ; Debug-Output "SETUP.INF: Configuring the DOS Subsystem." ; ifstr(i) $(!STF_WIN31UPGRADE) == NO ; shell "registry.inf" AppendToSystemPath "%SystemRoot%" ; endif ; read-syms ConfigSysAppend ; read-syms AutoexecBatAppend ; LibraryProcedure STATUS,$(!LIBHANDLE),VdmFixup $(AddOnConfig) $(AddOnBatch) ; ifstr(i) $(STATUS) == ERROR ; shell "subroutn.inf" PopBillboard ; EndWait ; read-syms NonFatalError2$(!STF_LANGUAGE) ; shell "subroutn.inf" SetupMessage $(!STF_LANGUAGE) NONFATAL $(NonFatal) ; StartWait ; endif ; ifstr(i) $(!STF_PLATFORM) == $(!PlatformID_Mips) ; set wowfile = krnl286 ; else ; set wowfile = krnl386 ; endif ; shell "registry.inf" MakeWOWEntry $(wowfile)

Next, comment out the following files from the TXTSETUP.SIF, INITIAL.INF and DOSNET.INF files so the files that support MS-DOS and Windows 16-bit applications will not be installed. If you are upgrading from an earlier version of Windows NT in which MS-DOS and Windows 16-bit applications were used, list these same files in the [Files.DeleteOnUpgrade] section of the TXTSETUP.SIF file. Lines in this section use the following format:

file, dir

where file is the filename and dir is the code number that is assigned (in the [WinntDirectories] section) to the directory in which the file is found.

1 These files are listed twice in the INITIAL.INF file. Be sure to remove both occurrences of each to avoid receiving an error message from Setup.
