stored with your originals.

3.  From the subdirectory (or diskette) where the IBMDOS.326 file is
currently located type:

     XCOPY IBMDOS.326 C:\IBMDOS.COM /R  <press enter>

		REMEMBER:  If you have compressed your C: drive you will also need to

APPLICATION SPECIFICS KNOWN TO DATE:

Wizardry 7 - Crusaders of the Dark Savant  -  apply this patch.

Vshield                                    -  apply this patch.

F15 - Strike Eagle III                     -  apply this patch and use
MEMMAX -U in Autoexec.bat


NOTE:

After installing this patch there are some other applications that may
return "Packed file corrupt" errors.  This may sound like a severe problem
but all you need to do is type MEMMAX -L prior to starting the application.
 The easiest way to do this is create a batch file that will turn off lower
memory (MEMMAX -L) for the application in question and then turn it back on
(MEMMAX +L) once you have exited that application. Word Perfect, for
example, will occasionally need this adjustment if used with this patch. 
The solution would be the following batch file:

MEMMAX -L
WP
MEMMAX +L

If you encounter any other applications that require the adjustment
mentioned above, please either call (800-638-9273) or fax (408-649-8209)
this information to the attention of the PATCH DEPARTMENT as we are
tracking this for our Engineering Staff.
