- HOW TO UNPROTECT "SpssPc" (tm)
- WITHOUT PROGRAM MODIFICATIONS
-
- If you wish to run "SpssPc" (ver. 1.1) from a hard disk, but
- are annoyed by the requirement for having the original disk 1 in
- drive A, then read on....
-
- Part of this ARC file is the program "SPSSFIX.COM". All you
- have to do is to include this program in your "autoexec" file when
- running SpssPc. For instance, your "autoexec.bat" might look like
- this:
-
- DATE
- TIME
- SPSSFIX
- (rest of autoexec.bat)
- .
- .
- .
-
- That's all there is to it. SpssPC will no longer look for the
- key disk in drive A.
-
- How does SPSSFIX.COM work?
-
- The protection logic for SpssPC is quite simple. On side 0, track 0E
- (hex) SpssPC searches for several "weird" sectors. SpssPC screens
- the disk I/O calls and when it sees a request for track 0E, it
- sends back a return code indicating that the sectors on this track
- were successfully found.
-
- Note: this program was written for SpssPC version 1.1. It may not
- work with subsequent versions if the protection scheme has been
- changed.
-
- A request:
-
- If you find this program of value and wish to encourage the
- availability of similar programs in the future, then you may wish
