SUMMARY
When some programs exit, or shell out to MS-DOS, they need to reload the command interpreter, COMMAND.COM. To make the process of reloading the command interpreter more efficient, you can place COMMAND.COM on a RAMDrive. To do this, follow these steps:


 * 1) In your AUTOEXEC.BAT batch file, copy the file COMMAND.COM to the RAMDrive.
 * 2) Set the COMSPEC environment variable to point to the copy of COMMAND.COM on the RAMDrive.
 * 3) Set the PATH environment variable to include COMMAND.COM's location on the RAMDrive.



MORE INFORMATION
The following is an example of copying COMMAND.COM to a RAMDrive called E:   COPY C:\COMMAND.COM E:\ SET COMSPEC=E:\COMMAND.COM SET PATH=E:\;... <--- Fill in the rest of your PATH
