The information in this article applies to:
- Microsoft MS-DOS operating system version 6.0
-------------------------------------------------------------------------------
SYMPTOMS
========
If you remove MS-DOS 6 Upgrade using the Uninstall disk you created during
installation, IO.SYS and MSDOS.SYS still have the MS-DOS 6 file sizes (the
original date and time are correct).
CAUSE
=====
This situation occurs because Uninstall overwrites the MS-DOS 6 IO.SYS and
MSDOS.SYS files with the previous versions of IO.SYS and MSDOS.SYS but does not
delete the MS-DOS 6 files first (nor does it truncate the files after
overwriting them).
MORE INFORMATION
================
Although this problem occurs with other versions of MS-DOS, the following table
only shows the files sizes before and after installation and uninstall with
MS-DOS 5.0 and MS-DOS 6.0.
