Here is how to unprotect the new version of ProKey (version 3.0,
which is copy-protected):
1. PLACE A WRITE-PROTECT TAB ON THE PROKEY DISTRIBUTION DISK!!!
2. Put the Prokey distribution disk in B: and DOS disk in A:
3. Make b: the default drive
4. Type A:debug pkload.com
Follow the DEBUG Script below:
-g 3ffc [you type this]
AX=0100 BX=3FE1 CX=0000 DX=03F4 SP=FFFE BP=41CA SI=0920 DI=0110

****NOW CHANGE DISKS IN DRIVE B:--USE A FORMATTED BLANK DISK.****
-w [you type this]
Writing 40CA bytes
-q [you type this]
ProKey is now unprotected. You may now manually copy all
remaining files from the ProKey distribution disk onto your fresh
disk in B:. The resulting PKLOAD.COM will start normally, and
may even be copied onto a hard disk and run from there without
the bother of putting the distribution disk into one of the
floppy drives!!!
