I agree with the view of the person above!

If you don't mind, can you publicly disclose the specific modification method?

Is there a logic lock available for download? I'm really interested in researching it.

The following is a quote from kevinet on 2003-6-21 20:37:06:
Is there a download for the logic lock? I really want to study it.


Is it for real or for simulation?

anson: I really haven't taken an apprentice yet, hee hee~~ But my current level is still far from the real masters! For example, the Dark-Destroy moderator is more familiar with ASM and program debugging, while I only know the basics in these aspects..

Moderator Wengier, stop being modest~~
Just from the two points of you streamlining IO.sys and modifying IO.sys to bypass the logic lock, it's obvious that your ASM skills are no ordinary!

Those with the moderator's IO.SYS file are not afraid now. Please teach, what is the difference between a real logic lock and a simulated logic lock, thank you

It should be a very small program (I don't know the difference between a real logic lock and a simulated logic lock. If possible, I want to study the real one. I hope the moderator has the key program). I want to study how it works.
Everyone must never use it for illegal purposes.

Actually, the "real" logic lock and the "simulated" logic lock are essentially the same. It's just that the former is "genuine" (KV300L++), and the latter is "pirated" (demo version). But the "genuine" one is very hard to find, while the "pirated" one can still be found.

Can the moderator publicly disclose the modification method for reversing the logical lock in IO.SYS?
