                       Patch for IBM DOS 6.0 and CDD 3.0

Our thanks to IBM for the quick response and their help!


There are two ways to fix the problem with running Clarion3 with IBM DOS 6.0

       ͻ
        Ŀ 
         Method 1.  
         
       ͼ

1) Replace the IBMDOS.COM with the update from this zip file.

   This is the version of IBMDOS.COM that's shipping in the latest
   version of the IBM DOS disk compression update package.

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

If a disk compression product (such as STACKER) is being used
-------------------------------------------------------------

A) Unhide the existing IBMDOS.COM in the root of the boot drive *AND*
   in the root of the compressed drive with the ATTRIB command.

   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 both the root of the
   boot drive and the root of the compressed drive.

   Ex:   COPY A:\IBMDOS.COM  C:\
         COPY A:\IBMDOS.COM  D:\  (if Stacker mapped boot drive as D:)

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

   Ex:   ATTRIB +r +h +s C:\IBMDOS.COM
         ATTRIB +r +h +s D:\IBMDOS.COM (if Stacker mapped boot drive as D:)

E) Reboot the machine, you're done.

If a compression product is *NOT* being used
--------------------------------------------
Same as above, but you can ignore the references to D:\IBMDOS.COM

         Method 2.  
         
       ͼ

2) A small TSR - FIXCLAR3.COM

To use the TSR, just run it before starting CLARION3 (i.e. put it into
either CDD.BAT or your AUTOEXEC.BAT file).

The TSR is smart enough to not install itself if the problem doesn't exist,
and will not load itself multiple times.
It also relocates itself up into the PSP to minimize it's memory footprint.
