I've created little program in Delphi to get the Bios SN.
The code is:

BiosSerialNo := String(Pchar(Ptr($FEC71)));

And this work both in Win98 and Win2000.

How come stealthFIGHTER's Delphi program worked if you can't access the bios memory area in 2000?

That sounds weird to me. It shouldn't be possible. I'd be glad to
give his program a test run...

I wonder why the application gives me totally incorrect values...
and why, when looking at the executable with a hex editor, I find
those same totally incorrect values in there. Could it be that the
application indeed does not read the bios, hmmm? ;).

I can't upload (slow) any picture to show you that this program works under Win2000 (on my PC) (note: this progr. is coded under Win98 with Delphi 3).

Well, it doesn't crash here. But it shows incorrect values. Values that
seem to be compiled into the app, not dynamically fetched.

There's probably no gaurantee that your BIOS has
it's S/N at the very same address as SF. Why
you're getting values from the .exe, ????

BIOS strings are at pretty standard positions on all recent hardware
(where "recent" is probably as old as early 90s). Now, I could theoretically
take the .exe to my kid brothers' PC that runs 98se, and see if it
has the same values there (meaning the exe is a hoax). Dunno if
I can be bothered though :).

This f@cking prog. really doesn't work under Win2000 :(. I've installed my D3 under Win2000 and compiled the source again and wtf > Access violation blah... . So as f0dder said the exe has probably the bios-info compiled in it.

My mistake.

procedure MainBoardBiosInformation;
MainBoardBiosName := String(Pchar(Ptr($FE061)));
MainBoardBiosCopyright := String(Pchar(Ptr($FE091)));
MainBoardBiosDate := String(Pchar(Ptr($FFFF5)));
MainBoardBiosSerialNo := String(Pchar(Ptr($FEC71)));
MainBoardBiosName := 'Unsupported';
MainBoardBiosCopyright := 'Unsupported';
MainBoardBiosDate := 'Unsupported';
MainBoardBiosSerialNo := 'Unsupported';

Didnt somebody just say that area of memory is protected? no?
