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
DS=0B4F ES=0B4F SS=0B4F CS=0B4F IP=3FFC NV UP EI PL NZ NA PO NC
-r cx [you type this]
CX 0000
:40ca [you type this]
****NOW CHANGE DISKS IN DRIVE B:--USE A FORMATTED BLANK DISK.****
-w [you type this]
Writing 40CA bytes
-q [you type this]
**************************************************************
**************************************************************
LAYOUT.COM is protected in the same way as PKLOAD.COM.
To "adjust" LAYOUT.COM, use the same procedure as for PKLOAD,
EXCEPT: Change A:debug pkload.com to A:debug layout.com
Change G 3ffc to G 1f8f
Change 40ca (setting CX) to 205d
That's it!
