If you have different versions of COMMAND.COM, MSDOS.SYS, and IO.SYS
on your computer, the following error message may appear when you boot
your machine:
Incorrect DOS Version
To work around this problem, you need to boot from an MS-DOS boot
disk, for example, the MS-DOS Uninstall disk.
RESOLUTION
To verify the versions of MSDOS.SYS and IO.SYS, type VER at the command prompt, then type COMMAND to verify the version of the command
interpreter.
If VER and COMMAND do not report identical versions and manufacturers,
you must reinstall the operating system so that COMMAND.COM and the
system files have the same version number and are from the same
manufacturer.
