The following information was taken from the Microsoft MS-DOS 5 Upgrade README.TXT file.



7.1 New CV.COM for CodeView

Users of CodeView versions 3.0 to 3.13 should use the program CV.COM to start CodeView. For more details, see the section on CodeView in the file APPNOTES.TXT.

7.2 Documentation Corrections

The following are corrections to the "Microsoft MS-DOS User's Guide and Reference": COMP /? Help:
Online help for the COMP command /d switch should state that the default format is hexadecimal.

EXPAND Command:
The example in Chapter 4 of the "Microsoft MS-DOS Getting Started" guide refers to the wrong installation and upgrade disks. The disk referred to as Disk 1 should be Disk 2; the disk referred to as Disk 2 should be Disk 3.

FORMAT Command:
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.
    With Task Swapper in MS-DOS Shell.
The UNFORMAT /p switch is not compatible with the /j switch.

7.3 Hercules Display Adapter (MSHERC.COM)

If you use MS-DOS Editor or QBasic with a Hercules display adapter, run MSHERC.COM before you run either program.

7.4 QBasic "On Error" Command

Online help for Microsoft QBasic incorrectly states that ON ERROR RESUME NEXT is a valid statement. The correct syntax is as follows:


7.5 SMARTDrive and Third-Party Partitions

If your system includes a third-party disk partition and you try to use SMARTDrive, you may receive a message stating that you cannot load SMARTDrive.

You can force SMARTDrive to load by specifying the /p switch. However, doing so may corrupt your hard disk if either of the following conditions is true:
    Your hard disk contains more than 1024 cylinders.
    Your hard disk is not supported by the system's ROM BIOS.
If you have partitions created by using third-party disk-partitioning software, use SMARTDrive ONLY if you are sure your hard disk contains 1024 or fewer cylinders AND it is supported directly by the system's ROM BIOS.
