 Problem:  User gets "Invalid disk change reading drive A:" after
           changing diskettes for an error message and with SHARE loaded.

 Solution: IBMDOS.COM

    SHARE is loaded and a user inserts a write-protected diskette in a disk
    drive.  User receives an error message.  User now inserts a different
    diskette and receives an error message requesting the previous diskette
    based on the different volume labels.  User cannot insert a different
    diskette.  Even a 'dir #:'  command will display the error.

    IBMDOS has been modified so that when a different diskette is inserted
    no error message will be displayed and it is accessible.

 This file is supplied and supported by IBM.


To use the new IBMDOS.COM file, follow the procedure below:

If a disk compression product (such as SuperStor/DS) is being used
------------------------------------------------------------------

A) Unhide the existing IBMDOS.COM in the root of the boot drive with the
   ATTRIB command.  If you have compressed drive C, also unhide the
   IBMDOS.COM in the root of drive C.

   Ex:   ATTRIB -r -h -s \IBMDOS.COM

B) COPY the current IBMDOS.COM to a safe place.

   Ex:   MD  \SAVE
         COPY \IBMDOS.COM \SAVE

C) COPY the new IBMDOS.COM on top of the old one, in all locations you
   unhid IBMDOS.COM.

   Ex:   COPY A:\IBMDOS.COM  \

D) Re-hide the new IBMDOS.COM file with the ATTRIB command in all locations.

   Ex:   ATTRIB +r +h +s \IBMDOS.COM

E) Reboot the machine, you're done.


If a compression product is *NOT* being used
--------------------------------------------
Same as above, but you only have to update C:\IBMDOS.COM.
