File Manager Brings over Wrong Hidden Files

 * }

Q84218

-

The information in this article applies to:


 * Microsoft Windows versions 3.1, 3.11
 * Microsoft MS-DOS operating system versions 5.0, 6.0

-

SUMMARY
When you use Windows' File Manager to format a floppy system disk on a computer that originally had IBM DOS installed and was upgraded to MS-DOS 5.0 or 6.0, the correct MS-DOS COMMAND.COM is copied over, and the incorrect IBMBIO.COM and IBMDOS.COM files may be copied to the system disk instead of the MS-DOS 5.0 or 6.0 files MSDOS.SYS and IO.SYS.

WORKAROUND
There are two workarounds to this problem:


 * Remove the two hidden IBM files from the root directory of the hard drive.
 * Format the system disks outside of Windows. The MS-DOS SYS.COM does not get confused by the hidden files.

MORE INFORMATION
When an IBM DOS system is upgraded to MS-DOS 5.0, the IBM hidden files are left on the hard drive because it is difficult to know if these files belong to IBM DOS or IBM OS/2. The IBM OS/2 files take up too much space to be copied to the MS-DOS 5.0 uninstall disk.
