SUMMARY
Pages 550-551 of the &quot;Microsoft Windows User Guide&quot; version 3.1 incorrectly indicate that the EMM386.EXE memory manager can be used to give MS-DOS applications expanded memory in standard mode.

However, in standard mode, EMM386.EXE is disabled.

MORE INFORMATION
Page 550 incorrectly states:

"You can run the [MS-DOS] application in standard mode, using EMM386.EXE to simulate expanded memory." Page 551 incorrectly tells you how to set up EMM386.EXE for use with MS-DOS applications in &quot;standard mode&quot; that use expanded memory:

Add a command line for EMM386.EXE to your CONFIG.SYS file.

  ... device=c:\windows\emm386.exe 512 This command line is supposed to allow EMM386.EXE to set up 512K of RAM memory as expanded memory for use with MS-DOS applications requiring expanded memory. However, this does not work. If you shell out to MS-DOS and run the MEM command (MS-DOS 4.01 and 5.0) or run MSD.EXE, you will see that there is no expanded memory available.

MS-DOS applications can use EMM386.EXE for expanded memory when Windows is not running.
