- UPDATES
-
-
- 1.0 Initial release of this program.
-
- 1.1 Bugfix. Found to be non-compatible with SCSI
- hard drives. Version 1.0 saved a hidden control
- file to the root directory of drive C. The
- program needed to access this file to remove
- itself. When the SCSI hard drive would not boot
- it became impossible for the user to access the
- hard drive without reformating or contacting me.
- Version 1.1 solves this problem nicely by
- restricting it's operation to drive A. It saves
- a non-hidden encrypted control file. This file
- is needed for removal, please make backups and
- store in a safe place.
-
- 1.2 Bugfix. If the disk in drive A were full
- (unlikely, but possible), the program would
- continue installation even though the control
- file was not properly saved. This version
- corrects the problem. Tightened code, modified
- control file signature to prevent the reading of
- previous versions control files.
