7.2 Documentation Corrections

The following is a correction to the Microsoft MS-DOS Getting Started manual:

Page 66 (steps 6 and 7 of the procedure):

To determine whether you have the correct version of EMM386.EXE, disregard the file dates (as stated in steps 6 and 7 of the procedure). Instead, to check which version of EMM386 you are using:

    Quit Windows, if you are using it.
    Type EMM386 at the command prompt.

    MS-DOS displays the version of EMM386 you are using.
    If the message indicates you are using version 4.33 or later, you are using the correct version. If you are using a version earlier than 4.33, expand and copy the newer version included with MS-DOS 5.0 by following step 7 of the procedure in Getting Started.
Page 77 (Lotus 1-2-3 version 3.1 won't start)

The information in this section also applies to Lotus 1-2-3 version 3.0.

The following are corrections to the Microsoft MS-DOS User's Guide and Reference:

If you can't use the FORMAT command to format an unformatted disk, try using the /u switch.

MIRROR Command:

You cannot use the MIRROR command with a network drive or any drive you created by using the ASSIGN, SUBST, or JOIN command.


Do not use the UNDELETE command in the following circumstances:
    When other programs are active.
    With the LOAD= command or the Shift+Enter key combination in Windows or MS-DOS Shell.
    With Task Swapper in MS-DOS Shell.

The UNFORMAT /p switch is not compatible with the /j switch.

RAMDRIVE.SYS Device Driver:

Valid values for the RAMDrive DiskSize parameter are 4 through 32767.

The following is a correction to the command-line Help:

COMP /? Help:

Online help for the COMP command /d switch should state that the default format is hexadecimal.
