assistant: Un giorno, Martin Preuss oso' discutere su Re: Copy Protect (naive quest....
But it's very easy to crack!
It doesn't exist a uncrackable copy protection!
My idea of an effective copy protection is that it takes a lot of time
to crack my software so people prefer to buy the original than
wait for a year or more for a free cracked version !

Write your reply.

assistant: Surely you must be joking.  I found this book utterly useless for a
newcomer.  Although the book clearly states in its Preface that the book
if for beginners without prior Assembly experience, nothing could be
further from the truth.  Much of the book is a reference--which wouldn't
make much since to a newcomer--and the rest is nothing more than code
fragments.  Even most of the C callable routines from TASM using the
simplified model directive, doesn't work correctly.  This is because it
is used in the wrong place!
If the newbie is planning on using TASM, I'd surely recommend Tom Swan's
Mastering Turbo Assembler.  This book will give him all the details of
the language and at the same time provide him with usable functions
(string library, etc.) that all assembly language programmers will/can
us at some point in time.  I'd also recommend Harley Hahn's Assembly
Inside & Out to accompany Tom's book.  It will provide code pseudo-code
for utilizing for/loop, while, do/until, if, if/else, if/else ladder,
and using a switch decision block.
If the guy is real lucky, he might be able to find a copy of Robert
LaFore's, Assembly Language Primer for the IBM PC/XT.  This book will
introduce him with using DOS DEBUG first, then moving on to MASM.
I'll agree with you on this one.  I seem to prefer the books more so than
spending hours reading a computer screen.  After all, you can't take
your computer too the bathroom and read too easily.
All-in-all, I think I'd recommend buying Borland C++ 3.1, since it comes
with an excellent C/C++ compiler, Assembler, Debugger, and Profiler.
Borland may even sell this still.  If not, I'm sure there are users
selling theirs around...

assistant: I wish things were that way!!!
I wish all languages were just the bare-bones compilers they should be, or at
least had standard versions that were just bare-bones. (bare-bones-C,
bare-bones-Pascal, etc..)
Since everything else is just a library call away, why not sell seperate
libraries?
It makes no sense to me.. many compilers have been CRIPPLED by the choices
made for the "standard library" .. short-sighted twits at borland and
microsoft.
They could sell bare-bones-C for $60, sell the "official" libraries for
another $120 .. special libraries for another $120 .. upgraded libraries as
well as upgraded compilers .. more bucks.. more bucks.. more bucks..
And more power for the users, as well..

Write your reply.

assistant: FISUBR is a math coprocessor instruction.
   MASM reference guide says:
   FSUBR/FSUBRP/FISUBR
   Subtract Reversed
   Subtracts the destination operand from the source operand and returns
   the result in the destination operand. If two registers are
   specified, one must be ST. If a memory operand is specified, the result
   replaces the value in ST. Memory operands can be 32- or 64-bit real
   numbers of 16- or 32-bit integers. If no operand is specified, ST (1)
   is subtracted from ST and the stack is popped, returning the difference
   in ST. For FSUBRP, the source must be ST; the difference (source minus
   destination) is returned in the destination register and ST is popped.

Write your reply.

assistant: I wrote something just like this (albeit for 5.25" diskette drives) back in
1984 or so, as a demonstration of how useless a certain major diskette
manufacturer's copy protection program was.
Regrettably, that code (.ASM, of course) is packed way way _way_ deep in my
Fibber McGee closet (which dates me, I guess, just like the code) .. and I
_really_ don't wanna drag it out.
Unless this is really really important.
But basically, this is what you do:
Hook INT 13, Service 2 (Read disk sectors).
  If they're NOT trying to read your drive, jump on to the old BIOS function.
  If the read is for your sector:
    If it's more than just your sector, you call the old BIOS function and
let it do the read.  However, you return an error (CF set).  And you set an
internal error flag.
  If it's just for your sector, don't even call the old BIOS function.  Just
return error and set internal error flag.
  If they try to read something _else_, you clear that internal error flag
and let the BIOS handle the call just like always.
Ditto, with INT 13, Service 3 (Write disk sectors).
Ditto with INT 13, Service 4 (Verify disk sectors).  You call the BIOS
function to do the work for you.  If it returns no errors, then you fake an
error (dropping the "number of sectors verified" by one and setting CF and
your internal error flag.
Naturally they're gonna try INT 13, Service 1 (Disk Status), when they get
that read, write, or verify error report, to find out just what happened.  If
it's your drive, and if the internal error flag is set, you return 4, "Sector
not found".  Otherwise you clear the internal error flag and let the BIOS
handle the call.

Which obviously calls for the "do what I meant, not what I told you"

Hmmm...strange.  Just doing a `dir' shouldn't affect the contents of the
disk at all.  The only thing I can think of is somehow the buffering
and/or caching is causing the anomoly.  I'm only guess, but from the
sounds of things, you could probably ask DOS to search for the first
file on the disk and ignore the result to prevent the anomoly from
happening.  If this works, I'd _definitely_ add a comment about why the
extra code is there and what it accomplishes.
Ah, in that case you must be using TASM.
Well, yes, that would likely come in handy now that you mention it.
