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]
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!!!
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!
