Loadhigh
Loads a program into the upper memory area (UMA). Loading a program into the UMA leaves more room in conventional memory for other programs. Use the systemroot\System32\Config.nt file, or the equivalent startup file specified in a program's program information file (PIF), to specify the programs to load high.
Syntax
loadhigh [Drive**:**][Path] FileName [parameters]
Parameters
[ Drive : ][ Path ] FileName : Specifies the location and name of the program you want to load. Filename is required.
parameters : Specifies any command line information required by the program.
/? : Displays help at the command prompt.
Remarks
Windows XP does not use this command. It is accepted only for compatibility with MS-DOS files.
To use the loadhigh command, you must include the dos=umb command in your Config.nt or equivalent startup file. For more information about the dos=umb command, see dos in Related Topics.
Before you can load a program into the upper memory area, you must install the Himem.sys extended memory manager. Use the device command in your Config.nt or equivalent startup file to install Himem.sys.
If you use the loadhigh command to load a program, Windows XP attempts to load it into the UMA. If there is insufficient space in the UMA, the program is loaded into conventional memory; the memory area used is not indicated.
The most convenient way to use the loadhigh command is to include it in your Autoexec.nt or equivalent startup file.
Examples
To load a driver into the high memory area (HMA), include the following line in your Autoexec.nt or equivalent startup file:
lh %systemroot% \system32\dosx
