- This patch allows the user to unprotect PrintMaster, published recently
- (1985) by Unison World, Inc. The following steps assume that DEBUG.COM
- and the file PMMAIN.EXE are on the default disk drive. If not, add
- a drive specifier (A:, B:, C:, etc.) to the file names shown below.
- The procedure is as follows:
-
- REN PMMAIN.EXE PMMAIN
- DEBUG PMMAIN
- S 0000 FFFE CD 13 (This should return an address in the form
- xxxx:6C73, where xxxx is the current code segment. If the
- second part of the address is not 6C73, you have a different
- version, and this patch probably will not work. If it is
- 6C73, proceed with the following steps.)
- E 6C73 90 90
- E 6C7A 90
- W
- Q
- REN PMMAIN PMMAIN.EXE
-
- The version you have now created will run from an unprotected
- floppy in drive A, but since some of the file names used by the
- program are hard coded to be on drive A, there is another step to be
- performed before it can be run from the hard disk or RAM disk.
- The DOS command ASSIGN A=C must be executed (assuming the hard disk
- or RAM disk is drive C). This will direct all calls for drive A to
- drive C, where the program and its files are.
