10 Here is how to unprotect the new version of ProKey (version 3.0,
20 which is copy-protected):
30 1. PLACE A WRITE-PROTECT TAB ON THE PROKEY DISTRIBUTION DISK!!!
40 2. Put the Prokey distribution disk in B: and DOS disk in A:
50 3. Make b: the default drive
60 4. Type A:debug pkload.com
70 Follow the DEBUG Script below:
80 -g 3ffc [you type this]
90 AX=0100 BX=3FE1 CX=0000 DX=03F4 SP=FFFE BP=41CA SI=0920 DI=0110
100 DS=0B4F ES=0B4F SS=0B4F CS=0B4F IP=3FFC NV UP EI PL NZ NA PO NC
110 -r cx [you type this]
120 CX 0000
130 :40ca [you type this]
140 ****NOW CHANGE DISKS IN DRIVE B:--USE A FORMATTED BLANK DISK.****
150 -w [you type this]
160 Writing 40CA bytes
170 -q [you type this]
180 ProKey is now unprotected. You may now manually copy all
190 remaining files from the PRokey distribution disk. The resulting
200 PKLOAD.COM will start normally--even from a winchester disk, without
210 requiring the distribution disk to be inserted in a drive!
220
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!
