The information in this article applies to:

  • Microsoft Windows NT Advanced Server version 3.1

SUMMARY

Page 272 of the Windows NT System Guide (page 277 of the Windows NT Advanced Server System Guide) includes LOADHIGH (LH) in a list of 16-bit Windows and MS-DOS subsystem commands. All of the listed commands are accepted when run from Command Prompt except LOADHIGH. If you attempt to use LOADHIGH from either CMD.EXE or the COMMAND.COM that comes with Windows NT, the following error message will appear: 

   The name specified is not recognized as an internal or external
   command, operable program or batch file.
LOADHIGH does work correctly if you use it in the AUTOEXEC.NT or equivalent startup file.

MORE INFORMATION

To use the LOADHIGH command in Windows NT, the following must be true:

  • The DOS=UMB command must be included in the CONFIG.NT or equivalent startup file.
  • The extended-memory manager, HIMEM.SYS, must be installed. Use the DEVICE command in the CONFIG.NT or equivalent startup file to install HIMEM.SYS.

When the LOADHIGH command is used to load a program, Windows NT attempts to load the program into the upper memory area (UMA). If there is insufficient free space in the UMA, Windows NT loads the program into conventional memory. Windows NT does not indicate which memory area is used.

NOTE: The MEM command can be used to determine where the program has been loaded.
